The FiberMania 40G QSFP+ SR4 Transceiver is a high-performance, short-reach optical module engineered for 40Gbps Ethernet, Infiniband, and high-density data center applications. Featuring four independent full-duplex channels, each capable of 10Gbps, it achieves an aggregate 40Gbps throughput over OM3 multimode fiber up to 100 meters. Its compact QSFP+ form factor supports high port density while minimizing system complexity and cost.

This transceiver utilizes MTP/MPO connectors and a CML-compatible electrical interface, ensuring reliable signal integrity and easy integration into switches, servers, and storage systems. Integrated digital diagnostics (DDM) enables real-time monitoring of optical power, voltage, and temperature, allowing proactive network management and ensuring stable, low-latency connectivity.

Designed for energy-efficient operation, the module consumes less than 1.5W with a single +3.3V power supply and meets RoHS-6 environmental standards. Its hot-pluggable design simplifies installation and maintenance, making it ideal for short-reach, high-speed networking in dense data center environments.
