From The Top: An update from Neil

Back in 1996, CityLink signed up INL (now Fairfax) as our first commercial customer. They needed to connect two offices in separate CBD buildings with LAN speeds, so CityLink installed a dedicated dark fibre network, and the rest is history.Neil de Wit

Today CityLink's FibreLink dark fibre service interconnects hundreds of buildings for dozens of customers. Its open access and simplicity (remember, it's just fibre), allows LANs to be interconnected without us getting in the way and interfering with your bandwidth needs.

From the earliest times, our business and technical staff have been ensuring that CBD's have an abundance of choices for high speed business access through our fibre infrastructure and believe it is mission critical for the city.

Now, our Government, under the BII project is looking to install dedicated fibre everywhere. Exciting stuff, and remember, we did it first.

The long and the short of FibreLINK

CityLink delivered the first FibreLINK service in 1995! Back then it was a revolutionary service, and today it is still making a huge impact with our customers. FibreLINK, which delivers an unlit optical fibre circuit, is still CityLink's most popular service because it offers customers freedom, reliability, security and performance.

Reliability and security are an inherent benefit of FibreLINK because data is not being switched, routed, or tunneled over a service provider's network - instead customers receive a dedicated purpose built point-to-point fibre circuit for their exclusive use.

FibreLINK also offers total freedom over the choice of technology, protocols and the optics that light up the fibre optic circuit. The performance of FibreLINK is unparalleled because an optical fibre circuit has almost unlimited bandwidth potential.

Actrix socks it to the big boys thanks to FibreLINK

Established in 1989, Actrix Networks Limited is one of those classic Kiwi success stories - you know the kind - where someone with a good idea starts a business in their garage and grows it to the point where it's a serious player in its market.

In this case, Actrix wasn't simply one of the first ISPs in New Zealand; they were actually one of the first in the world - fifth, in fact. Back in 1989, when most of us old enough to remember were lusting after a chance to use a PC with a brand-new Intel 486 processor, the founders of Actrix were dreaming about the internet and the technology that powered it.George

With 20 years in the business under their belt, Actrix has thrived where others have tried and failed. George Reedy, Group General Manager for Actrix, says that their success is thanks to a very high level of technical expertise and an above-the-call-of-duty approach to customer service. "It was about getting the technology nailed, right from the very start, and we are very proud of our customer service record. These things are fundamental to our operation, and not just something we pay lip service to."

Actrix's long-standing relationship with CityLink has been a big part of their drive to use the right technology and provide great service. "We were one of CityLink's first ever customers," explains George. "Back in 1995, Wellington City Council's vision for boosting the local economy included the idea that Wellington be a ‘connected' city. We believed in the same thing - after all, our clients were generally Wellington-based businesses with large bandwidth needs. CityLink was able to offer a reliable and ‘wide' network of fibre. We got behind them and haven't looked back since."

Actrix use FibreLINK, which is one of CityLink's core offerings which provides a dual fibre network, and Actrix attach their own technology to power it up.
"We use FibreLINK a lot. It meets our needs, security-wise, and we get all the bandwidth we require. For many of our customers, data security is crucial. We get paranoid on their behalf, which is exactly what they expect of us," George says.

"Our customers are wildly diverse, with little in common, except for the fact that they are bandwidth hungry. Whether it's e-commerce, huge data flows, social networking, or web development, the uniting feature of our customers is that they do business on the internet, and we can provide them with a reliable, safe and flexible service, with oodles of bandwidth, thanks to FibreLINK."

Of course, just because CityLink is the only significant supplier of high quality data networks in Wellington today, doesn't mean that Actrix have stayed with us simply because they don't have a choice. "We choose CityLink because they are very good with fibre technology, as well being exceptionally easy to do business with," George explains.

"No one else provides the same level of service. On the very rare occasions that an issue arises, CityLink's staff are here, in our office, working with our technical people to provide a solution. That kind of relationship is priceless."

Tech Talk: Practically Utilising the Bandwidth Potential of FibreLINK

It is often said that the bandwidth capabilities of fibre optics are almost unlimited - but really how unlimited is it? It is thought that the ultimate achievable capacity of an optical fibre is 12,500Gbps (12.5Tbps); however there are no transmission systems capable of delivering this massive capacity today.

There are two ways to practically and economically maximise the utilisation of fibre optics today; increase the speed of the transmission optics, and the use of optical Wave Division Multiplexing (WDM) systems to give multiple parallel channels.

Transmission optics for Ethernet networking are readily available up to 10Gbps bandwidth. The IEEE, the body that oversees the development of Ethernet standards, is currently working on 40Gbps and 100Gbps transmission standards. 40Gbps transmission systems are already available for some other telecommunications systems such as Synchronous Digital Heirarchy (SDH).

WDM is a method for multiple optical transmission systems to share a single fibre by transmitting different colours (wavelengths). Course WDM (CWDM) mux/demux units and coloured optics are becoming affordable as a way to increase bandwidth or to use a single pair of fibres to support multiple different transmission systems. CWDM defines 18 channels between 1270nm and 1610nm, each of which can carry up to 2.5Gbps. CityLink has been asked by a number of customers if they can use CWDM on their FibreLINK service? In general, the answer is "yes, but there are a number of factors that must be considered".
