OIF adds a short-reach design to its 1600ZR/ ZR+ portfolio
Saturday, January 18, 2025 at 12:51PM The OIF (Optical Internetworking Forum) has broadened its 1600-gigabit coherent optics specification work to include a third project, complementing the 1600ZR and 1600ZR+ initiatives.

The latest project will add a short-reach 'coherent-lite' digital design to deliver a reach of 2km to 20km and possibly 40km with a low latency below 300ns.
The low latency will suit workloads and computing resources distributed across data centres.
"The coherent-lite is more than just the LR (long reach) work that we have done [at 400 gigabits and 800 gigabits]," says Karl Gass, optical vice chair of the OIF's physical link layer (PLL) working group, adding that the 1600-gigabit coherent-lite will be a distinct digital design.
