Today's network bandwidth demand is being enabled by advanced DSP engines. Increasing deployed bandwidth is accomplished through two factors; a pure baud rate / data rate increase per channel and an adaptability to accommodate many different and changing network topologies.  To enable the flexibility required in todays network, these DSP’s not only adapt in real time to a wide range of network impairments (i.e. loss, noise, distance, dispersion), but also report the values they are compensating for.  This dramatically simplifies network planning and monitoring. 

Tools of the trade

Keely Portway takes a look at what fibre engineers consider to be the most essential characteristics for test and measurement equipment, and how vendors are designing-out complexity to meet this demand

On with the show for OFC

The Optical Fiber Communication Conference and Exhibition (OFC 2020) will go ahead as planned, amidst concerns over the Coronavirus.
