The Gigalight 200G QSFP-DD PSM8 NRZ 10km optical transceiver (GDM-SPO201-LR8C) is an eight-channel, hot-pluggable, parallel, fiber-optic QSFP Double Density module designed for 2×100-Gigabit Ethernet PSM4 and InfiniBand DDR/EDR applications. It is a high-performance module for data communication and interconnects.
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 an 24-fiber MTP/MPO connector. This module incorporates Gigalight proven circuit and optical technology to provide reliable long life, high performance, and consistent service.
