The CFP2-DCO-400G-D is a CFP2 form factor coherent pluggable module, compliant with the CFP MSA CFP2 Hardware Specification. It supports a range of baud rates and modulations including QPSK, 8QAM, and 16QAM, which enables operation at 100G, 200G, 300G and 400G over a single wavelength, across hundreds to thousands of kilometers. On the host side, the module can accommodate a variety of signal types including 4×100GE, 2×200GE, 1×400GE, OTUCn (n = 1…4), and OTU4. On the line side, the module supports 100G, 200G, 300G, and 400G interfaces with different modulation formats and forward error correction (FEC) codes. Multiple 100G clients can be multiplexed onto a single 200G, 300G, or 400G line-side interface. It is an ideal choice for scaling network capacity in access, metro aggregation and metro-regional core networks.
