Optical interconnect provider Acacia Communications announced a single chip coherent module to deliver 1.2 Terabit on a single channel.

The AC1200-SC squared module is powered by Acacia’s 1.2T Pico Digital Signal Processor chip. It is designed to help network operators support 100 GbE clients and emerging 400 GbE clients on the edge, metro, long-haul and underwater.

The flexibility of the module makes it ideal for multi-haul applications that range from edge to terrestrial and submarine networks, said Acacia CTO Benny Mikkelsen.

That flexibility allows adjustments in modulation and baud rate to handle different transmission capacities and reach in a network, said Bill Gartner, senior vice president of optical at Cisco, an Acacia customer. He said Cisco’s customers can achieve significant cost savings with the module by freeing up valuable spectrum and enabling higher use across the entire network. Cisco has used the module in customer deployments of Cisco’s NCS 1004.

The new module makes a footprint that is 40% smaller than the 5 x 7 modules for 400 G, yet it supports 1.2 T, Acacia said. Pricing was not announced. The module will be demonstrated at the European Conference on Optical Communications in Dublin, Ireland Sept. 22-26.
