We in :Net are very lucky to have SmartOptics with us on our side.
We were in the same situation this year as last year, desperate in need for WDM optical transceivers, and a couple of phone calls later they confirmed availability on the wavelengths we needed and that they wanted to be a part of TG yet again.
And because they regard TG as very awesome, we already started talking about what we can do for TG15. How cool isn’t that? π
You didn’t read last years article? Who are SmartOptics you say? SmartOptics is a awesome company specializing in high quality optical transceivers and WDM systems. One of their newest products that we in :Net is totally in awe over is the new embedded WDM system T-series platform;
http://www.smartoptics.com/products/active-wdm/t-series/
This is a 1RU WDM system which supports 10Gig, 40Gig and coherent 100Gbps, that scales up to a 2000km reach (T-9910-C) and without the need for additional DWDM equipment. Aside from the obvious benefit from the pizza box design, the system is modular with hot-swappable redundant PSU’s and fan module.
For more detailed information about the T-series system and pictures;

Coherent 100G on one pair of fiber cable is possible through something called super-channel: http://en.wikipedia.org/wiki/Super-channel – defined in the standard OTU4, which can be very easily described by this picture:

We have been working on improving the infrastructure inside of Vikingskipet.
We started with documenting a lot of cable runs at TG13, and we have between TG13 and TG14 been laying plans for how to make the situation better for not only TG14, but for years to come.
One part of the planning was to visit Vikingskipet and map the cable runs in January, to see how and where things are – and to better map the needs.
After that we had a design meeting which led to the design we landed on:
(This is not the final version.)
Based on the design we could calculate how much equipment we needed. And we started to call around to find the best prices. When we landed on a minimum cost of the installation, we got the cost approved in the budget and we could start ordering the equipment.
Quickly after the first and most important batch of equipment arrived (the two cable drums), and we could travel up to Hamar to start the installation.
We have completed the first of two weekends of installation. In the first weekend we completed all the cable runs, and everything is ready for the next weekend – when we will weld the fiber optics (with pigtails) and install them in duplexes into ODF’s.
The longest run around the hall is 633 meters of G12 fiber (6 pairs) and the most traffic intensive run are 353 meters of G48 (24 pairs) – 986 meters in total, only short of 14 meters on 1k meters. Everything is single mode.
I recommend you to read a bit here if you don’t know what fiber optic cables are:
http://en.wikipedia.org/wiki/Optical_fiber_cable
This is what a typical ODF looks like:
The blue “connectors” is called fiber adapters.
The small cables beneath is the actual fiber, and they are welded onto pigtails:
Which is connected into the fiber adapter, which also could be called a extender.
The reason why we say G12 (6 pairs) is because most fiber optic installations there’s one single fiber for Rx (receive) and one single fiber for Tx (transmit). There are possibilities to actually run Rx and Tx on one single fiber – the method uses different wavelength for Rx and Tx which requires special optical transceivers which can translate this.
There’s a lot of different form factors for optical transceivers, but the most common today is called SFP (+) – the form factor is SFP and the + indicates that it is 10Gig ready:
In our setup we have mostly SFP+ and we are running single mode 10G transceivers between all of our nodes.
Most of the permanent infrastructure we already have is either old multi mode, or too few single mode pairs.
With this improvement we are able to run a more redundant setup, we can run more 10Gig connections between more places and will give us much more flexibility.
Also worth mentioning is that we have purchased MPO cables, which is a G12 single mode cable with one single connector in both ends where you connect cassettes with connectors (they work as a mini-ODF):
(The MPO cable with MPO connectors to the left and to the right the cassettes).
We will drop these cables from the bridge in the top (roof), this way can we do the cabling down to our distribution and core equipment in no time – at the same time as the cabling is not disturbing anyone.
Beneath are pictures from the first trip to Vikingskipet, where we pulled all the cables through Vikingskipet. Next time is welding time! π

Tech:Net has visited Vikingskipet for a cable inspection…
We reveal some of our… less important findings:
The OSI (Open Source Interconnection) 7 Layer Model is 30 years old, but still highly applicable. If you don’t know it; read about it and learn it! Or maybe time for a little refresh, even if you already know about it? π

We got the call from Cisco who let us know that they want to continue sponsoring us with their AWESOME network equipment… which makes it possible for us to build an awesome network for everybody attending TG14 π

We are legally late out with the goodiebag this year. :/
Hope you nice people can forgive us for that π

Thanks to all of you who were interested in the VPN.
We wished that this could have been a reality, that would have been cool.
But alas, our speculations and wishes became this years aprils fool π
We love you all! π
It’s over one year until next TG:

Hang in there! We will keep you posted… π
