New Acacia Interconnects Address Network Access and Edge Applications

Provider of high-speed coherent optical interconnect products Acacia Communications, Inc has announced the general availability of two new high-speed coherent optical interconnect products for “ZR” applications. Enabled by Acacia’s low-power, integrated designs which leverage  proprietary Digital Signal Processor (DSP) and silicon photonic technologies, the new 100G/200G CFP2-DCO ZR and next generation low power 100G CFP-DCO ZR address demands for growing capacity in network access, edge, and enterprise campus applications.

The new products support the requirements of unamplified applications beyond the 40 km reaches standardised in the industry, and extend to 80 km and beyond. The CFP-DCO ZR module is capable of supporting the 18 W power class that was widely deployed for 10 km client applications. Both modules also offer high-capacity and low-power consumption solutions designed to reduce the complexity, power usage and cost of high-bandwidth interconnects.

“Based on our experience with network operators, we see increasing demand for 100G and above in access aggregation markets,” says Jimmy Mizrahi, Vice President, Global Portfolio with ECI.  “We believe coherent 100G and 200G ZR solutions, in compact pluggable form factors, will be an attractive solution for network operators with requirements for reaches greater than 40 km in applications such as 5G backhaul and cable access.”

“Traditionally, coherent optical transmission was primarily used for longer reach applications, but traffic patterns are changing in ways that are leading to the need for high capacity interconnects that target shorter reaches in a power efficient and cost effective manner. ZR optics address this need,” adds Tom Williams, Senior Director of Marketing for Acacia Communications. “Acacia pioneered the coherent ZR offering with our industry first CFP-DCO form factor and our vision is to continue to expand the use of coherent technology in shorter reach applications.”

Shorter reach applications are believed to be an emerging opportunity for coherent optical interconnects, and are receiving significant attention from industry standards organisations. Standards are under development for coherent ZR-class interfaces at 100G, 200G and 400G, adapting traditional 80 km ZR requirements for coherent transmission. Applications ranging from the interconnection of hyper-scale datacentres to the aggregation of residential access networks and 5G backhaul are driving converging requirements for these coherent interfaces.
