Description
The F-tone Networks Technologies FTQD-2H-PSMLR4xx is a Eight-Channel, Pluggable, Parallel, Fiber-Optic QSFP DD PSM8 for 2×100 Gigabit Ethernet , Infiniband DDR/EDR Applications. This transceiver is a high performance module for data communication and interconnect applications. It integrates eight data lanes in each direction with 208 Gbps bandwidth. Each lane can operate at 26Gbps up to 10km over G.652 SMF. These modules are designed to operate over singlemode 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 F-tone Networks Technologies proven circuit and Optical technology to provide reliable long life, high performance, and consistent service.
