Arista adds coherent CFP2 modules to its 7500 switch

Arista Networks has developed a coherent optical transport line card for its 7500 high-end switch series. The line card hosts six 100 gigabit CFP2-ACO (analogue coherent optics) and has a reach of up to 5,000 km.

Several optical equipment makers have announced ‘stackable’ platforms specifically to link data centres in the last year.

Infinera’s Cloud Xpress was the first while Coriant recently detailed its Groove G30 platform. Arista’s announcement offers data centre managers an alternative to such data centre interconnect platforms by adding dense wavelength-division multiplexing (DWDM) optics directly onto its switch.

ClariPhy samples a 200 Gigabit coherent DSP-ASIC

ClariPhy Communications has entered the 100 Gigabit coherent merchant chip market after announcing first samples of its LightSpeed-II devices. 

The family of coherent digital signal processing ASICs (DSP-ASICs) is manufactured using a 28nm CMOS process. "We believe it is the first 28nm standard product, and leaps ahead of the current generation [DSP-ASIC] devices," says Paul Voois, co-founder and chief strategy officer at ClariPhy.
