2020 Good Quality Qsfp Transceiver - 40Gb/s QSFP+ CWDM 40km DDM Duplex LC optical transceiver – Topticom
2020 Good Quality Qsfp Transceiver - 40Gb/s QSFP+ CWDM 40km DDM Duplex LC optical transceiver – Topticom Detail:
Product Description
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, on the receiver side, the module 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 G694.2. 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.
