The Q100G-DD-ZR-DCO is a high-performance 100G DWDM QSFP28 optical transceiver designed for long-reach transport networks, metro core interconnect, and data center connectivity over existing C-Band DWDM infrastructure. The module delivers a full 100 Gbps data rate using 4x25G electrical lanes combined into a single 100G PAM4 optical signal, optimized for long-haul applications where EDFA amplification and dispersion management are deployed.
This transceiver is ideal for service providers, metro network operators, enterprise data centers, and cloud infrastructure environments that require reliable 100G connectivity across distances up to 80 km over standard single-mode fiber (9/125 µm).
