The Gigalight 200G QSFP-DD PSM8 NRZ 10km optical transceiver (GDM-SPO201-LR8C) is designed for 2x 100G PSM4 Ethernet links reach up to 10km over Single-Mode Fiber (SMF). Features The 200G QSFP-DD PSM8 (dual PSM4) module integrates eight data lanes in each direction. Each lane can operate at 25.78Gbps up to 10km over G.652 SMF. It is designed to operate over single-mode fiber systems using a nominal wavelength of 1310nm. The electrical interface uses a 76-contact edge type connector. The optical interface uses a 24-fiber MTP/MPO connector. This module incorporates Gigalight proven circuit and optical technology to provide reliable long life, high performance, and consistent service.
