Keep up to date with our progress for Janet6 - the new Janet infrastructure - as we move through to the design, build and roll-out stages of the project.

Well, it's been some time since I wrote on this blog so I thought I'd give you a little update on where we are.  The engineering guys have been working hard across the country to roll-out of the core of Janet6.  W/C 20 May commissioning of this part of the network was completed and they are now going through a process called 'snagging' which involves labelling the fibres correctly, installing/replacing patch leads etc.

So it’s been a while since my last blog update (apologies for that), and the main reason for this is that we’ve all been fairly busy recently!

Recent highlights include:

Sat in the bar of a dual-carriageway stained Norwich hotel, trying to digest the bland tasteless chilli con carne they had on offer (note to chef: more chilli powder does not equal more taste), nothing much to do other than catch up on emails and ask the barman no less than 4 times to put football on the TV, I may as well do a quick blog update.

To expand on Rachel’s blog entry from last week: we’re now the proud owners of ≈2400km of dark fibre that makes up the Janet6 core. This is the central ‘ladder’ structure that runs up the country and consists of key points of presence in London, Bristol, Birmingham, Nottingham, Leeds, Manchester, Glasgow and Edinburgh, and plenty more inbetween. The core of the network then extends out to the regional fibre infrastructure and connects to the 18 regional networks, so it’s clearly an integral part of Janet.

I haven't been on this blog for a while, but I thought this was worth a mention.  On Wednesday this week (6 Feb) we formally accepted the Janet6 core fibre and PoP infrastructure from SSET.  This is pretty significant as we are ahead of time, so well done to all of the guys who have been working hard to make this possible!  It's only phase 1 of the acceptance process I'm told, but it's a great start!  

Next will be the fibre instrastucture from the core to the the regional network entry points, then the central infrastucture will be fully in place.

In the latest issue of Janet News that is about to hit all good desks (and maybe a few of the rest of you too), I’ve written a little bit about some of the technologies that will be deployed at the transmission level in Janet6 – Wavelength Selective Switches, Coherent Detection, and probably the shortest description of Dual Polarisation Quadrature Phase Shift Keying that has ever been seen.  There are many other components at various layers that will make up Janet6, and I’m going to start below the ground and work my way up.

The location for writing this week’s blog update (I admit they’re starting to stray from being weekly at the moment) is a pub that sits in the shadow of the Centre Point building in central London. Part of the scope of the Janet6 project is to provide fibre connectivity to a group of ‘Strategic Research Facilities’, these are Janet customer sites from the research sector that have a specific demand for high capacity network connectivity.

Once a month at Janet we have a company meeting during which different people from different parts of the company are invited to speak about their particular area of expertise. Having worked at Janet for over 10 years I’d somehow managed to avoid this duty, until today. It was my turn to give an update on the Janet6 project, something I should clearly know a bit about, and this is the subject of this week’s photo. More relevant to the Janet community is that the talk I gave today is a vastly scaled down version of what you’ll be able to hear about at Networkshop this year (see below).

Very little to report this week (as you can imagine) - the office is almost empty, there's no milk in the fridge, and any pressing work items were dealt with last week. Today will consist of finishing off a few bits of admin, tidying up, getting things lined up for the new year, and then heading out for lunch with my extended family.

Blog Article

It has been pointed out to me by someone from the upper echelons of the Janet family that a blog post that doesn't contain a photo is now considered something of a disappointment, so a colleague kindly snapped me hard at work this afternoon.
