The OIF’s 400ZR coherent interface starts to take shape

Roy Rubenstein, Gazzetabyte

The Optical Internetworking Forum’s (OIF) group tasked with developing two styles of 400-gigabit coherent interface is now concentrating its efforts on one of the two.

When first announced last November, the 400ZR project planned to define a dense wavelength-division multiplexing (DWDM) 400-gigabit interface and a single wavelength one. Now the work is concentrating on the DWDM interface, with the single-channel interface deemed secondary.…

 OIF Approves Agreement on Polarized Multiplexed Quadrature Modulator

Starts 112G inside Multi-Chip-Module Project, Google’s Bikash Koley speaks at Q1 Meeting

Members of the Optical Internetworking Forum (OIF) recently passed an Implementation Agreement (IA) for an optical integrated Polarization Multiplexed (PM) quadrature modulator for coherent applications with nominal symbol rates up to 64GBaud. The agreement supports the 16QAM modulation format for 400G applications.

“As we go to higher data rates, we need higher performing optical components that maintain a reasonable level of complexity.” said Karl Gass of Qorvo and the OIF’s PLL Working Group – Optical Vice Chair.…
