Description
F-tone Networks’s FTQ5-2H-CWDM4-10KM Optical Transceiver modules are designed for use in 200 Gigabit Ethernet links over single-mode fiber. The module can convert 4-channel 53.125 Gbps electrical data to 4-channel optical signals, and multiplex them into a single channel for 212.5 Gbps optical transmission. Similarly, it optically de-multiplexes a 212.5 Gbps input into 4-channel signals, and converts them to 4-channel output electrical data on the receiver side.
They are compliant with the QSFP+ MSA and with IEEE 802.3cn 200GBASE, SFF-8679, and CEI-56G-VSR-PAM4 standards. Digital diagnostics functions are available via the I2C interface as specified by CMIS4.0. The transceiver is RoHS 2.0 compliant and lead-free per Directive 2011/65/EU.
