400G QSFP-DD LR8 10km光模块

Description
The F-tone Networks FTQD-4H-LR8xx is an Eight-Channel, Pluggable, Parallel, Fiber-Optic QSFP Double Density for 400 Gigabit Ethernet Applications. This transceiver is a high performance module for 10km 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 10km using G.652 SMF with KP-FEC. These modules are designed to operate over single mode fiber systems using LAN-WDM 8 wavelengths. The electrical interface uses a 76 contact edge type connector. The optical interface uses duplex LC 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.
