The QSFP28 digital optical (DCO) transceiver supports 100G transmission over distances of up to 120 km (dispersion-limited, optionally expandable to 300 km) for edge network applications. On the host side, the module can accommodate IEEE 100GE Ethernet or ITU-T OTN OTU4 signals. The line-side interface specification is in accordance with IEEE Standard 802.3-2022 100GBASE-ZR [8] and ITU-T G.698.2 DW50U-8A2(C)F / DW100U-8A2(C)F [11], which defines a 27.95GBd dual-polarized differential QPSK modulation format.
