Acacia, now part of Cisco, has added to its portfolio of 400G coherent pluggable solutions, based on its Greylock 7nm DSP, with the new Bright 400ZR+ and ER1 400G pluggable coherent optical modules. The Bright 400ZR+ QSFP-DD pluggable coherent optical module with high optical performance is designed for seamless deployment in ROADM line systems. The 400G ER1 QSFP- DD pluggable coherent optical module has a rich feature set including client multiplexing and interoperability based on both OIF and OpenZR+ protocols. Acacia’s ER1 400Gmodule is a cost effective and flexible solution for unamplified 40 km point-to-point latest 51.2Tbps, 64*800G liquid cooled, co-packaged ethernet switch, TP- B6940-64X2. As a part of OIF’s Physical Link Layer Interoperability Demo 2022 program, the switch, whichmeasures 442mm × 43.6mm× 730mm, (1RU) demonstrated interoperability with a number of capabilities. These include support for up to 64 × 800GbE or 128 × 400GbE ports, using the Senko SN-MT optic interface and the Broadcom 51.2Tbps Switch. The Co-Packaged Optical module is equipped with Intel 3.2Tbps 8×400Gbps FR4 & DR4 3.2T optics and support for both integrated-laser-source and external-laser-input optical modules, which are assembled
on the front panel. Cooling is by means of a cold-plate liquid cooling system which, says Ragile, has high efficiency and quietness for switch ASIC and optical

offering even greater flexibility for network operators who want to deploy this pluggable technology. For customers primarily targeting filtered (AWG- based DWDM) point-to-point applications, the 400ZR and OpenZR+ modules are an effective pluggable solution. Acacia’s Bright QSFP-DD module is designed to expand the applications for this technology by addressing a variety of ROADM architectures
period ending January 29, 2022. The aggressive ramp of these products has been faster than any previous coherent technology generation. Early demand has been largely driven by metro DCI use cases, but service providers are actively working to deploy this technology in a wide range of applications. With these new modules, Acacia has developed a portfolio of solutions that further address the varying needs of network operators, while driving economies of scale on a common technology platform.
such as those with colourless multiplexing. With greater than 0dBm transmit optical power and high transmit OSNR, the Bright 400ZR+ gives network operators more flexibility to address a range of brownfield and greenfield applications utilising the high- density QSFP-DD form factor. Acacia says early adopters of its 400G pluggable product family have been driving strong demand that has resulted in over 50,000 port shipments, with more than 20,000 shipped during Cisco’s second fiscal quarter for the
