The FiberMania 100G QSFP28 LR1 BIDI Transceiver is a high-performance, single-fiber optical module engineered for cost-effective, high-density 100G Ethernet networks. Utilizing bidirectional (BIDI) technology, it transmits and receives 100Gbps data over a single strand of single-mode fiber, with 1270nm for Tx and 1330nm for Rx. This approach effectively doubles fiber capacity, reducing cabling complexity and infrastructure costs.

This hot-pluggable QSFP28 module is equipped with a simplex LC connector and integrated Digital Diagnostic Monitoring (DDM) for real-time monitoring of optical power, voltage, and temperature. Its compact form factor, low power consumption, and high signal integrity make it ideal for 5G fronthaul, metro networks, and data center interconnects where efficient fiber usage and reliable high-speed performance are essential.

Fully compliant with QSFP28 MSA, IEEE 802.3bs, and 100G Lambda LR specifications, the transceiver ensures plug-and-play deployment, multi-vendor interoperability, and robust performance in modern optical networks.
