Description
The 100G ZR QSFP28 DCO Transceiver is a long-reach 100Gbps coherent optical module designed for Ethernet and optical transport applications over single-mode fiber. Using digital coherent technology with dual-polarization DQPSK modulation and integrated Staircase FEC, it provides extended optical reach and reliable high-capacity transmission across metro, access, and transport networks. The module supports distances of up to 80km without optical amplification and up to 120km under dispersion-limited conditions, while its full C-band tunable wavelength architecture supports 50GHz and 100GHz DWDM channel spacing. With a compact hot-pluggable QSFP28 form factor, CAUI-4 and OTL4.4 host interfaces, and power consumption below 5.5W, it provides a flexible solution for telecom networks, wireless infrastructure, cable access systems, and long-distance data center interconnects.
