FAQ
The 100G QSFP28 LR1 CWDM Optical Transceiver is a high-speed, cost-efficient module engineered for 100G Ethernet and data center interconnects over single-mode fiber. Utilizing Coarse Wavelength Division Multiplexing (CWDM) technology, it enables 10km transmission, allowing multiple 100Gbps channels over a single fiber and optimizing existing fiber infrastructure.
Designed for metro networks, 5G fronthaul, enterprise backbones, and data center aggregation, this QSFP28 transceiver provides reliable performance via four parallel 25.78Gbps lanes with NRZ electrical signaling. The module supports KP4 FEC, enhancing signal integrity across longer distances, while its hot-pluggable duplex LC connector ensures seamless integration into existing SMF networks.
Equipped with integrated Digital Diagnostic Monitoring (DDM), the transceiver offers real-time tracking of critical parameters such as temperature, voltage, and optical power. Fully compliant with QSFP28 MSA, 100G Lambda MSA, IEEE 802.3cu, and SFF standards, it guarantees interoperability with multi-vendor equipment and scalable deployment for next-generation optical networks.
