Brief Introduction
The Vchung 100G ZR QSFP28 DCO transceiver supports 100G transmission over distances up to 120km (dispersion limited, optionally extendableto300km) for edge network applications. On the host side, the module can accommodate IEEE 100GE Ethernet or ITU-T OTN OTU4 signals. Thelineside coherent interface specifications are aligned with IEEE Std. 802.3-2022 100GBASE-ZR [8] and ITU-T G.698.2DW50U-8A2(C)F / DW100U-8A2(C)F[11], which define a 27.95GBddual-polarization difffferential QPSK modulation format.
