Posted on 14th January 2019 by Russell Trafford-Jones

From the NANOG conference (North American Network Operators’ Group), Richard A Steenbergen tells us everything we need to know about fibre optics; essential knowledge in today’s network-centric world – though fibre has been in frequent use in broadcast for a long time.

Whether this is new to you, or you’ve been using fibre for ages, you’re sure to get something out this detailed look at optics covering:

How fibre works (the basics, fibre types and limitations, etc)
Optical power (understanding dBm, loss, using light meters, etc)
Working with optics (choosing the right type, designing optical networks, etc)
DWDM (how it works, muxes, OADMs and ROADMs, amps, etc)
Dispersion and other impairments (what is it, why do we care, how do we fix it)
Optical Myths (can I hurt myself looking into fibre, can I overload my optic, etc)
An update on the latest state-of-the-art optical technologies and trends.
