40G QSFP+ LX4 2km@SM and 150m@OM4 / 40G QSFP+ IR4 2km

Teosco QSFP-LX4 is a transceiver module designed for applications over both multimode (MM) and single mode (SM) fiber with transmission distances of up to 150m on MM fiber (OM4) and 2km on SM fiber. QSFP-IR4 is a transceiver module designed for applications over single-mode (SM) fiber with transmission distances of up to 2km on SM fiber. The module converts 4 inputs channels of 10Gbps electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gbps optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gbps input into 4 CWDM channels signals, and converts them to 4 channel output electrical data. The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm. It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA).
