QSFP+ Dual OPTEC 40G MM LC 6dB 150m VCSEL/PIN TX850/900 DDM

The QSFP+ OPTEC 40G MM 2xLC BiDi transceiver is a high-performance optical module designed for fast and reliable data transmission in modern fiber optic networks. The Dual BiDi version enables communication over two optical fibers, providing two independent optical paths. This allows reuse of existing 10 Gbps fiber infrastructure when upgrading to 40 Gbps, minimizing network modernization costs.

The module operates over multimode fiber (MM) and supports data transmission up to 150 m using OM4 cable or up to 100 m with OM3 cable. Each of the two 20 Gbps channels simultaneously transmits and receives signals at two wavelengths over a single multimode fiber. Transmission is handled by 20G VCSEL lasers at a nominal wavelength of 850 nm, while reception is performed by PIN photodiodes at 900 nm, enabling full-duplex communication with throughput up to 40 Gb/s.

The module supports DDM/DOM optical diagnostics, providing real-time information about operating conditions such as signal power, temperature, and supply voltage.
