The FiberMania 40G QSFP+ ER4 Transceiver is a high-performance optical module designed for long-reach single-mode fiber links, delivering reliable and low-latency 40Gbps connectivity. Featuring four independent full-duplex channels, each capable of 10–11.2Gbps, it aggregates to a total bandwidth of 40Gbps, making it ideal for interconnecting switches, routers, and servers in modern data centers.

Engineered with an ER4 1310nm wavelength, this module supports long-distance transmission up to 30km over standard single-mode fiber (SMF). Its MTP/MPO optical connector ensures compatibility with QSFP+ MSA-compliant equipment, providing a cost-effective solution for high-density networking environments.

With integrated digital diagnostic monitoring (DDM), the transceiver enables real-time tracking of temperature, voltage, and optical performance, allowing proactive network management. The module operates efficiently at low power (max 1.5W) and complies with RoHS-6 standards, ensuring energy-efficient and environmentally responsible deployment.
