Acacia Communications, a developer of high-speed coherent optical interconnect products, has announced the general availability of its pluggable coherent CFP2-DCO module, which supports 100G and 200G transmission.

The module is designed to help cloud and telecommunications providers reduce operational and capital expenses, increase reach and accelerate time-to-market of high-capacity solutions. The modules are suitable for a wide range of network applications, including data centre interconnect, metro access, metro core, long-haul, as well as emerging applications including remote PHY and client optical interfaces up to 80 km.

They are said to simplify network management and reduce operations costs for providers by enabling an Acacia-based eco-system through its network equipment partners. The company believes that these compact pluggable modules will allow its customers to offer some of the lowest power solutions available in the optical transport industry.

Key features
Pay-as-you-grow deployment model: Defers the deployment cost, including that of the digital signal processor, of additional ports until additional bandwidth is needed.

Digital host interface: Streamlines integration into existing network equipment and supports field plugability without the need for complex calibration. The use of pluggable optics means that a failure in a single module will affect only the module’s port, not the entire line card.

Flexible modulation: 100 Gbps transmission using QPSK modulation for metro-core and long haul applications and 200 Gbps for metro-access applications using either 16QAM for backward compatibility or 8QAM for greater reach and fewer regeneration stages.

Benny Mikkelsen, Founder and CTO, commented, “Our CFP2-DCO can address a wide range of networking applications in a compact form factor. Our team has done a great job to develop this low power solution, while maintaining high performance.

“With the Optical Internetworking Forum developing a CFP2-DCO Implementation Agreement, this form factor is positioned for wide adoption in the optical networking industry and with support for up to 400G, the CFP2-DCO form factor can offer network operators a long term return on investment.”

Initially sampled in 2016, Acacia’s CFP2-DCO supports four times the faceplate density of the CFP-DCO. It incorporates its Meru DSP ASIC, based on 16nm CMOS technology, and its silicon photonic integrated circuit. Internal layer 1 encryption can be enabled for enhanced security applications.
