Tight new fibre-optic testing limits needed for higher bandwidth apps

Posted on : August 15, 2014

With the ratification of 40 and 100 Gbps ethernet fibre standards, optical requirements are tighter than ever before. Yet testing methods have not caught up.

Also consider with the introduction of 10Gbps over ethernet, the maximum power loss budget for multimode fibre links has dropped significantly, and it is clear changes in testing standards are essential and urgent.

While an accuracy of 0.5 to 1dB might have been tolerable in the past, it is not acceptable with the 10Gbps or higher standards, especially as the demand for 1.5dB maximum power loss with OM4 fibers for 40 and 100Gbps applications requires precise test equipment and test procedures.

ISO/IEC 14763-3 was launched in 2006, with amendments added in 2010, in order to reflect the new tighter budget in test methods and equipment. The major changes are:

  • Launch and tail test cords with controlled end-faces.
  • Reference connectors with very low loss.
  • 1-and 3-test cord methods for reference setting with LSPM devices.
  • 2-test cord methods are not acceptable.
  • Introduction of encircled flux for accuracy of multimode light source.
  • Detailed procedures of LSPM and OTDR devices.
The main reason for these changes is accuracy and reliability. With a budget of 1.5dB for 40/100Gbps, a test tolerance of 1dB is not acceptable and testing with outdated or inaccurate equipment/methods doesn’t make sense.
 
In the end, both 1 and 3-test cord methods of reference setting provide standards-compliant results.

Synergy Telecoms courses cover testing of fibre as well as copper and utilising latest processes and technologies and latest industry info.

Different devices and technologies within a modern home or business rely on a fast broadband connection, which NBN will provide.

Homeowners need to ensure the contractors they use to perform work on their telecommunications systems are accredited for those types of installations.

From 1 July 2014, specialist cabling such as DATA cabling, Coaxial Cabling, Optical Fibre and some others require technicians to hold specialist endorsements on their Open Cable licence. At Synergy Telecoms we have courses to cater for these requirements – call us to find out the best suitable courses for your.

Fibre to the node or fibre to the premises?

Posted on : June 25, 2014

At the Home or Business Premises

What impact will this have on cabling within the residential premises?

Probably not a lot as in most cases the customers who are made aware and do need the full benefit of high speed networking throughout their premises will have category 5e or 6 cabling installed at build stage or by retrofitting. Fibre in the average premises would not be of benefit in fact it would create its own problems,

Consider this. The Fibre To The Premises network is single mode fibre terminating at the premises on an NTD. In this case the NTD is also a media converter, converting light energy to electrical energy, ready for the standard RJ45 (equipment plug). Now if you had some silly idea to go fibre in the premises with the inherent fibre high loss connectors over short distances. Your fibre media would be multimode, not single mode. You would have to supply a media converter and power to convert the FTTP NTD electrical energy back to light energy. This does not make sense. High speed data cable under 100 metres will have all you would ever need for your LAN up to 1 gig (or 10 gig) without power. And no, you cannot just plug your fibre into the FTTH (NBN etc) fibre for a lot of technical and regulatory reasons.

The other users who are not so interested in all this jargon and future stuff, will just keep using their existing cable/s whether it be cat 3 or cat 5 etc and would have access similar to what they have now.  

As the demand for bandwidth continues to grow there will be more and more consumers upgrading their premises to category 6 cabling and if they have not pre-wired their premises they will need to either retrofit cables or live with the limitations of WiFi and PLC type technologies.

 

Difference between FTTN and FTTP

What is the difference and what impact will it have on your business or personal communications?
The most commonly used technology by Telcos to connect to the premises follows:

Copper
Traditionally in nearly every suburb a carrier builds a telephone exchange which would connect to their existing network and extend telecommunications services to all the residential and commercial premises and in some cases weird locations like traffic lights, speed cameras and various monitoring equipment and or other locations that are not normally considered as premises.
https://gallery.mailchimp.com/ac0a0e233355f14c4da9dbd4b/images/Figure1.png

Figure 1. Traditional copper customer access network

You can see the “main cable” with its “main pairs” leaving from the telephone exchange to the pillar (in a street or on a corner near you) The “distribution cable” carries the “O pairs” to the house and telephone inside the premises. From the pit and joint in the street outside or near to the premises, the connection is provided by using twisted pair copper cable. This section is called the “lead-in” cable.

 

The main cable you see in Figure 1 can be a 100 pair or a larger cable from the telephone exchange to the pillar. From the pillar a cable runs along the street from pit to pit, these pits can be seen on the side walk between houses. This cable could be a 10, 30 or 50 pair cable. Then, from the pit, a 2 pair cable runs into the premises and terminates on a telephone socket.

In most cases the cable running from pit to pit is enclosed in a conduit and the two pair cable to the premises is also in a conduit up to a termination box “wall box” on the side of the house.
What is the difference between the Fibre to the Premises (FTTP) and Fibre to the Node (FTTN) besides the obvious, the name?

FTTP (Premises) is based on running fibre from the point of presence of the carrier all the way to the premises. In most existing suburbs the point of presence will be the existing telephone exchange. Whilst there are some options as to how you run the fibre cable to the premises, this article will only look at GPON as this is the network architecture chosen by Telstra, Transact and NBN co.
https://gallery.mailchimp.com/ac0a0e233355f14c4da9dbd4b/images/Figure2.png

Figure 2 FTTP (Premises)

In the FTTP architecture there is a fibre cable which connects to an Optical Line Terminal Unit in the telephone exchange and at the other end to a fibre splitter in the Fibre Distribution Hub (FDH). The splitter takes one fibre from the OLT and converts it into 32 individual fibres on the local cable which connects to a multiport. From the multiport there is a drop cable that connects to the Optical Network Termination (ONT) which in the case of NBN co is referred to as the NTD (Network Termination Device). This is the NBP (Network Boundary Point). GPON technology requires power at the exchange and in the premises. The FDH is passive, no power required.

FTTN (Node) on the other hand is based on running fibre to the Node (similar location to the pillar), then from the node to the premises using the existing (or upgraded) copper cable already in situ. In this case the fibre goes from the carrier’s point of presence which in most cases will be the existing local telephone exchange. The fibre terminates on the node. The node is an active device so power is provided. This will require running an alternate power backup to cater for black outs.

One large benefit of FTTN is the fibre infrastructure already exists to the node in many newer locations. These installations have already taken place over the past 15 to 20 years by Telstra. Thus saving a whole lot of duplication (and money).

From the node to the premises, the existing (or upgraded) copper cable is used. The technology on the copper side of the node will be the same DSL service. This normally runs at around 8 to 12 Megs download speed with a reasonable bandwidth to do just about anything over the net.

This does not take into account the “black spot” areas of very low grade copper and joints. However it would appear the NBN Co, so far, have not looked at these areas in their early role out, favoring other areas other than black spot, for some reason. For example some areas of Prospect NSW have a speed of around half a Meg download. This is not good enough. So we will see how soon this area gets a fibre or copper upgrade. The technical people are looking at up to 50 Meg by copper in the street, in the future.

The reason for the increase in speed is simply because the distance from the node to the home has been significantly reduced so the impact of the physical limitations of twisted copper pair is reduced by reducing the length of the cable. It should be noted that in many cases customers can choose to have fibre installed at their own cost, instead of using the existing copper to ensure the highest speeds are available for their businesses.

Smart Wiring-Telecommunications

Smart Wired© is a symbol owned by the ICAA (International Copper Association Australia) a body promoting the use of copper across industry, including telecommunications. Some time ago the industry bodies were quick to see the advantages of using the smart wired logos (above) and many technicians, engineers, cablers and electricians are unaware that the consumer guide, installer handbook and a code of practice for cablers on home wiring can be used in telecommunications.

ACMA mandated endorsements/specialist competencies for broadband will be able to use the smart wired quick guides (for consumers to help plans), installer handbook and code to sign off their work with the smart wired logo, as well as providing the mandatory ACMA TCA1 forms. www.registeredcablers.com.au

How importaint is Fast Speed Broadband to you?

Posted on : March 18, 2014

Houses without broadband could be worth as much as 20% less than comparable properties with a good connection, according to experts who say superfast speeds are increasingly important to prospective homebuyers.

With soaring numbers going online to perform everyday tasks or to work from home, a robust connection is considered so vital that the propertysearch website Rightmove has added a broadband speed checker button to every one of its listings, alongside details of transport links and schools. Estate agents report that rising numbers of buyers are willing to pull out of a deal if broadband is not available in that area.

Speed of your Broadband connection also relies on the quality of cabling inside your home or business. As a technician you need to give your client right advice on what is required to have a reliable internet connection.

It is a recommended norm to install Structured (DATA) Network cabling inside the home to allow for current and emerging technologies – you need to ensure you are qualified and licenced to perform this work for your Customer. ACMA Open cable licence will only let you endorse installation up to Category 3 level (telephony cable). From July 2014 it will be mandatory to hold Endorsements on your licence to perform specialised work – eg Structured Cable, Coaxial Cable, Optical Fibre and other.

Call our office for an obligation free consultation to ensure your qualifications are up to date!

ESSENTIAL WORK PRACTICES JUNE

DEADLINE FAST APPROACHING!

Posted on : May 5, 2014

On 1 July 2012, the Australian Communications and Media Authority (the ACMA) amended the regulatory requirements applicable to registered cablers. These amendments take effect from 1 July 2014 and apply to all registered cablers undertaking specialised cabling work within customer premises.
 
From 1 July 2014, registered cablers must have the applicable endorsements, or have attained the applicable competencies, in order to undertake any type of specialised cabling work.
 
Specialised cabling work is any installation, maintenance or repair work involving any of the following types of telecommunications customer cable;
 

  1. Broadband (data or co-axial cable in a lift or the home/small office environment); or
  2. Structured (data cable such as Cat 5 or Cat 6); or
  3. Optical-fibre cable; or
  4. Co-axial cable.

 
Registered cablers who have previously attained endorsements for Cat 5, Fibre and Co-axial cabling are not required to attain any additional competencies because these endorsements are equivalent to the new Structured, Optical-fibre and Co-axial competencies respectively. Registered cablers, who do not have the applicable endorsements or have not yet attained the applicable competencies, have until 30 June 2014 to do so.
 
Background
 
The amendments mandated new competency requirements effective from 1 July 2012 with a 2 year phase-in period. The amendments were made to ensure that registered cablers have the appropriate skills required to undertake specialised cabling work for the current and emerging customer cabling environment.
 
Prior to 1 July 2014, the ACMA’s Cabling Provider Rules (CPRs) only required that a person had to have the appropriate cabling registration (Open, Restricted, or Lift), issued by one of the five registrars, to undertake telecommunications customer cabling work – that is, it was not mandatory for them to have any endorsements or competencies.
 
After 1 July 2014, in addition to having the appropriate cabling registration, it is now mandatory for a registered cabler to have the applicable endorsements or competencies in order for them to undertake the specialised customer cabling work indicated above.
 
Failure to attain the applicable competencies does not mean that your cabling registration will cease to be valid. However if a registered cabler does not have the applicable endorsements or competencies it will limit the scope of cabling work they are permitted to perform.
 
The amendments have no effect on the aerial and underground requirements, as such they were not specifically mentioned. A registered cabler is required to hold the appropriate competencies, or endorsements, for any work including aerial and underground they will be undertaking after 1 July 2014.
 
Registered cablers are only required to have an endorsement, or a competency, for the type of cabling work they will be performing.  If they will only be performing structured (data) cabling work they will only be required to have a Cat 5 endorsement or a Structured competency. Similarly, they will only be required to have a Co-axial or an Optical fibre endorsement or competency if they will be performing these types of cabling work.

Qualifications – are you keeping up with the times?

Posted on : April 1, 2014

Based on our article over at Aquatel on smart home growth, future proofing and keeping up to date with your licenses is very important to provide your clients with the best solutions.

It is your responsibility as a technician to advise customer on the best practices and recommended cable systems in use today. Do you still install a beige 2 pair phone cable throughout your customer’s home? Did you know that it is now a recommended standard to install Structured Cable system throughout the premises whether it’s residential or commercial building?

As an industry professional, it is your duty to do the right thing by the customer and install the system that customer will be able to use now AND in the near future, plus they will keep coming back to you knowing you won’t sell and install outdated systems and technologies.

What you do need to ensure is that you are Qualified to perform this work. From July 2014, ACMA Open Cable licence will not be enough – you must hold appropriate endorsements for the work you perform. Structured (DATA) cabling will require you to have Structured Cable endorsement on your Open Cable Licence.

If you are not sure what qualifications you need for the work you perform, or need to upgrade and do extra training, give us a call!
Remember, you only have until July 2014, don’t get left out!

Fibre to the Node Trial

Posted on : April 1, 2014

To rent, not buy.

NBN Co has confirmed it is in discussions with Telstra to lease access to the telco’s copper network to trial fibre-to-the-node technology in several areas of NSW and Victoria.

The contract would fall outside the existing $11 billion definitive agreements between the two organisations, and would allow NBN Co to pilot a FTTN build in Umina on the NSW Central Coast and Epping in North Melbourne.

NBN Co is expected to rent, rather than purchase the copper – the government-owned wholesaler said today it did not expect there to be a “value transfer” involved at the end of the Telstra negotiations.

Communications Minister Malcolm Turnbull has previously said he expected Telstra to hand over access or ownership of its last-mile copper for FTTN for no additional cost.

NBN Co plans to build two small scale copper serving area modules, “erecting kerbside node cabinets which will connect [NBN fibre] to spare copper pairs in the Telstra pillar”. Neither sites were to receive FTTP in the next year under the previous plan, according to an NBN Co spokesman.

NBN RSPs will be invited to participate in the trial and help test whether Telstra’s copper network – which has faced criticism over quality and maintenance concerns – can be used to provide high-speed broadband. The trial will cover up to 200 locations across both regions.

NBN Co is also independently currently trialling fibre-to-the-basement throughout several suburbs in Melbourne, rolling fibre to nodes in communications rooms of apartment and office blocks in Carlton, Brunswick and Parkville. The trial has produced download speeds of 108Mbps and upload speeds of 48Mbps.

Under Communications Minister Malcolm Turnbull’s new multi-technology mix model for the NBN, customers will be connected by the most “economically efficient technology” for each location.

NBN Co said today it expects to begin transitioning to the new model from next year.

“The company is determined to stabilise and improve the efficiency of the rollout, and to help provide ongoing certainty for the Australian construction industry. As a consequence, the existing fibre to the premises (FTTP) rollout in the fixed-line footprint will continue throughout calendar 2014,” it said today.

“Accordingly construction orders continue to be issued and FTTP deployment continues to areas in line with the company’s current guidance for FY14, on top of the 351,046 premises already passed by fibre as at 31 December 2013.”

NBN Co will provide more details on the transition in its corporate plan, due later this year.

It also confirmed today it is currently renegotiating existing contracts with contractor partners. It said the discussions were “business as usual” to issue new work packages and would not involve entirely new contracts.

In its first half-yearly results presentation today, NBN Co revealed a 50 percent increase in capital expenditure to $1.2 billion for the six months to December 31 2013 – a result of “continued expansion of the network” compared to the six months to December 2012.

Operating expenses grew 50 percent to $500 million, and revenue came in 63 percent higher to $48 million for the half.

Revenue was boosted by a fourfold increase in telecommunications earnings, which grew to $21.8 million.

NBN Co posted an operating loss of $715 million, compared to the $430 million loss it posted at the end of 2012. NBN Co does not expect to post profit for the next few years during its construction phase.

Assets (including pits, ducts and pipes) grew 118 percent to $7.7 million, and the total number of users on the NBN grew to 131,000 from 34,500 in the last half of 2013. Around 80,000 of those are fibre users.

NBN Co’s total average revenue per user rose to $36.50.

Employee expenses grew 23 percent to $189 million, a result of a 32 percent boost in headcount to 2949. The company had around 3450 workers working on the build of the NBN at the end of 2013.

New Fibre Requirements

Posted on : October 2, 2013

The recent publication of AS/NZS 3080:2013 brings with it some much needed clarity for the ICT community with the inclusion of Amendments 1 and 2, and the injection of some new requirements.
The overall document has leapt from 132 pages (2003) to 200 pages as a result of this.

As AS/NZS 3080 is a direct descendant of ISO/IEC 11801, all additional requirements, and further guidance of the parent document specific to Australia and New Zealand, are captured in Appendix ZA as per the previous edition.

Most changes and updates are predominantly focussed around Optical Fibre, with the only significant Copper addition being that of the dreaded alien crosstalk requirements for copper classes EA and FA (alien crosstalk of Class F is considered to be as good as the alien crosstalk performance for class EA). Thankfully for installers and customers alike, the requirement for this time consuming test sequence is addressed within the new Standard. It states that if cable manufacturers can better the values for coupling attenuation as stated in 6.4.15.1, then the requirement is met by design (of the cable) therefore negating the need for AXT testing. Of course, it’s not just a case of saying that the cable outperforms the requirements – it has to be backed up by a Statement of Conformance from that cable vendor which is based on laboratory reports.
