Description
The Finisar FTLC9141SENM is a high-performance 40GBASE-LR4 QSFP+ optical transceiver engineered for long-distance 40 Gigabit Ethernet applications. It uses 4-lane LAN-WDM optics operating around the 1310 nm wavelength range, multiplexing four wavelengths into a single LC duplex fiber pair.
With a reach of up to 10 km over standard single-mode fiber, this module is widely used in data center interconnects, enterprise networks, and metro aggregation layers. It is fully hot-pluggable, consumes low power compared to earlier 40G modules, and is compliant with QSFP+ MSA standards.
The module supports full digital diagnostics (DOM) for monitoring temperature, voltage, laser bias, and optical power levels, ensuring stable and reliable operation in demanding environments.
