II-VI reveals ultra-low power DSP for 100Gb/s coherent transmission
II‐VI Incorporated has completed the tape-out of its Steelerton digital signal processor (DSP) for 100Gb/s coherent transmission in optical access and aggregation networks.
The growth of 5G wireless and high-speed broadband services is driving the explosive demand for coherent transceiver technology optimised for optical access networks. While service providers currently deploy coherent transceivers in core networks and data centre interconnects, they are seeking new designs that meet their high volume, low cost, low power dissipation, and small size requirements for access networks.
II-VI’s Steelerton DSP, miniaturised and with ultralow power dissipation, typically of 2W, was designed specifically to enable 100Gb/s digital coherent optics in a pluggable QSFP28 format, one of the most widely deployed 100Gb/s transceiver form factors in access networks.
