400G QSFP-DD PSM8 2km光模块

Description
The F-tone Networks FTQD-4H-PSMDR4 is an Eight-Channel, Pluggable, Parallel, Fiber-Optic QSFP Double Density for 2×200 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnection applications. It integrates eight data lanes in each direction with 8×26.5625GBd. Each lane can operate at 53.125Gbps up to 2km using G.652 SMF with KP-FEC. These modules are 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 MPO16/MTP16 APC connector. The Common Management Interface Specification (CMIS) for QSFP DD modules. This module incorporates F-tone Networks Technologies proven circuit and EML technology to provide reliable long life, high performance, and consistent service.
