40G QSFP+ LR4 10km / 20km

Teosco QSFP-LR4 10km/20km is designed to operate over single-mode fiber (SMF) system using 4 CWDM channel in 1300 band and links up to 10km/20km. The module converts 4 inputs channel 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 10Gbps 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) and compliant to 40G QSFP+ LR4 of IEEE 802.3ba.
