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.
