100Gbps Bi-Directional Simplex LC QSFP28 Transceiver

100G QSFP28 BIDI • 20KM Single Fiber • Simplex LC • Low Power <4W • DDM Supported

The 100Gbps Bi-Directional (BIDI) Simplex LC QSFP28 Transceiver is a high-performance optical module designed for 100G Ethernet, data centers, ISP backbone networks, enterprise fiber infrastructure, and telecom applications. It enables full-duplex 100Gbps communication over a single strand of single-mode fiber (SMF), reducing fiber requirements and lowering deployment costs.

Utilizing PAM4 modulation, EML laser technology, and an integrated PIN receiver, this module supports transmission distances up to 20 km. It features a simplex LC connector, integrated Digital Diagnostic Monitoring (DDM), low power consumption, and compliance with major QSFP28 industry standards.
