Data centre interconnect drives coherent

  • NeoPhotonics announced at OFC a high-speed modulator and intradyne coherent receiver (ICR) that support an 800-gigabit wavelength
  • It also announced limited availability of its nano integrable tunable laser assembly (nano-ITLA)  and demonstrated its pico-ITLA, an even more compact silicon photonics-based laser assembly
  • The company also showcased a CFP2-DCO pluggable

NeoPhotonics unveiled several coherent optical transmission technologies at the OFC conference and exhibition held in San Diego last month.

Ferris Lipscomb“There are two [industry] thrusts going on right now: 400ZR and data centre interconnect pizza boxes going to even higher gigabits per wavelengths,” says Ferris Lipscomb, vice president of marketing at NeoPhotonics.

The 400ZR is an interoperable 400-gigabit coherent interface developed by the Optical Internetworking Forum (OIF).

Optical module makers are developing 400ZR solutions that fit within the client-side QSFP-DD and OSFP pluggable form factors, first samples of which are expected by year-end.

2012: The year of 100 Gigabit transponders

Oclaro has detailed its 100 Gigabit coherent optical module that will be available from the second quarter of 2012. The MI 8000XM, a 5x7-inch 100 Gigabit-per-second (Gbps) transponder, uses NTT Electronics' (NEL) analogue-to-digital converter/ digital signal processor (DSP) ASIC at the receiver that compensates for transmission impairments.

 

“The world is moving to coherent, there is no question about that”

Per Hansen, Oclaro
