Fibre infrastructure and CWDM developments

The most interesting things I saw at IBC last week were not software updates or new 4k workflow tools (save us from "workflow tools"!) but some developments from our good friends at Barnfind. Their current CWDM products top-out at 18-wavelengths on a single fibre, and if you need to pack more signals (synchronous broadcast; HD/SDi, [...]

Barnfind’s high-speed data router and optical CWDM for TV infrastructure

Root6’s SI dept spent a few days last week in Norway as the guest of Barnfind in Sandefjord. Norway seems to be a lovely country if not a tad expensive (£24 for a round of three pints).  Barnfind are a small company whose engineers used to be with Nevion – you’ve probably come across their [...]

Measuring fibre cabling and the problem of encircled flux loss

  Last week I went on a very interesting training day courtesy of Nexans – data cable & parts supplier. I went looking forward to learning all about the new standards surrounding catagory-8 cabling for 40 and 56 Gigabit ethernet (a massive 1600Mhz of bandwidth down a twisted pair cable!) and the new GG45 connector; [...]

Cladding vs. Core Alignment fusion splicers

For seven years we've been using Tritec Fase II fusion splicers; we have two kits composing the splicers themselves (camera or microscope inspection), clevers and finishing ovens for the splice-protectors. If you're in the business of bespoke fibre then fusion splicing really is the only way to go as you get superior performance in termination [...]

Beware the fibre contamination!

These are two pictures taken down my hand-held fibre microscope - you can see the core and buffer of two examples of fibres that were spliced maybe three months ago in a new building. I suspect builder/decorator dust contamination and even though they have had their cover-pieces on they aren't air-tight and so we're now [...]

Graded Index fibre optics

In fibre optics, a graded-index or gradient-index fibre is an optical fibre whose core has a refractive index that decreases with increasing radial distance from the fibre axis (the imaginary central axis running down the length of the fibre). Because parts of the core closer to the fibre axis have a higher refractive index than [...]

Video and high-speed networks – article in Broadcast Engineering Magazine

Read the article on BE's site; As video data rates increase, installation engineers must become as familiar with fibre as they are with coax. Many types of fibre and twisted-pair copper must be purchased pre-terminated. Runs of 3Gb/s in copper require special attention to cable type if long runs are required. It may be necessary [...]
