II-VI shrinks an optical line system into an OSFP module

II-VI has developed an optical line system that fits inside a pluggable module. 

The advent of coherent pluggable modules implementing the 400ZR standard allows switches and routers to be linked across separate data centres. Now, with a pluggable optical line system, a dedicated line-system platform is no longer needed to send the 400ZR signals over a fibre. 

Sanjai ParthasarathiIn turn, the network operating system on the switch manages the optical line system directly such that a separate optical management software layer is no longer needed.

“We have shrunk an entire pizza-box line system into a small pluggable,” says Sanjai Parthasarathi, chief marketing officer at II-VI.

Indeed, one customer refers to the II-VI pluggable product - dubbed the OSFP-LS - as a ‘zero-rack-unit’ platform.

Ciena uses software to dip into the photonic layer

Ciena has enhanced its control plane and line elements to enable software to control the optical networking layer. The additions are part of Ciena's OPn network architecture evolution to enable greater visibility and automation. "It is about putting software into a system to allow you to program the photonic line," says Michael Adams, vice president of product & technology marketing at Ciena.

"For an SDN controller to control a photonic line, we need to present it as a programmable layer. The infrastructure is now there to be programmed."
