T1-QSFP-40G-LR4 is designed for 2m-10km optical communication applications. It is compliant with 40GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, the receiver optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals and converts them to 4-channel output electrical data.
The central wavelengths of the 4 CWDM channels are 1271nm, 1291nm, 1311nm, and 1331nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module.
T1-QSFP-40G-LR4 is designed with form factor, optical/electrical connection, and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA), and to meet the harshest external operating conditions including temperature, humidity, and EMI interference.
