The CFP2-DCO-200G-D is CFP2 form factor coherent pluggable module compliant to the CFP MSA CFP2 Hardware Specification, based on DP-mQAM modulation, polarization diversity coherent Intradyne detection and advanced electronic link equalization. The CFP2-DCO coherent transceivers are capable of supporting flex-grid DWDM tuning and can provide 400GBase-DCO throughput over single-mode fiber (SMF) up to 80km using an LC connector. Additionally, these transceivers offer support for digital optical monitoring (DOM) which allows access to. The 100G/200G Coherent CFP2 DCO MSA is Pluggable Digital Coherent C form-factor optical transceiver designed for high-speed optical networking applications such as: Telecom Metro/Long-haul, Wireless Backhaul and Hyperscale Data Center Interconnect (DCI). Letter C in the CFP2 naming is an acronym. A 2U optoelectronic converged platform, 400G high-speed transmission DCI solution. GIGALIGHT provides a series of BER testing tools (checker) for 10G SFP+, 25G/32GFC SFP28, 40G QSFP+, 100G QSFP28, 200G. This topic describes the names of optical modules used by WDM products. Basic format: [Maximum rate] [Encapsulation type] [T version] [ (Application scenario, FEC type@modulation format, flex rate or not, coherent or not, wavelength tunable or not, spectrum range, transmit optical power range. NADDOD's 200G modules come in QSFP56, QSFP-DD form factor shape, support 200G InfiniBand, Ethernet and are used over Single-Mode and Multi-Mode Fiber as a media.
