Infinera goes multi-terabit with its latest photonic IC

In his new book, The Great Acceleration, Robert Colvile discusses how things we do are speeding up.

In 1845 it took U.S. President James Polk six months to send a message to California. Just 15 years later Abraham Lincoln's inaugural address could travel the same distance in under eight days, using the Pony Express. But the use of ponies for transcontinental communications was shortlived once the electrical telegraph took hold. [1]

The relentless progress in information transfer, enabled by chip advances and Moore's law, is taken largely for granted. Less noticed is the progress being made in integrated photonic chips, most notably by Infinera.

PMC unveils OTN framer for IP core and edge routers

PMC-Sierra’s latest Optical Transport Network (OTN) framer chip for IP core and edge routers doubles throughput to 240 gigabit.

The Meta-240G frames IP router traffic using OTN before passing the traffic to the transport network. Line-rate encryption is included on-chip to secure traffic between data centres and traffic in the cloud.

Adding OTN to a router delivers several benefits, says PMC. OTN helps identify networking faults more quickly and simplifies the monitoring and enforcement of service-level agreements. OTN also includes forward-error correction which benefits optical link performance.
