Description
F-tone Networks’s FTQD-4H-2Q5-Oxxx MMF Active Optical Splitter Cable is used in 2 X 200 Gigabit Ethernet links over OM3/OM4/OM5 multimode fiber, which provides connectivity between system units with a 400GbE connector on one side and two separate 200GbE connectors on the other two sides. The cable connects data signals from each of the 8 MMF (Multi Mode Fiber) pairs on the single QSFP56-DD end to the dual pair of each of the QSFP56 multiport ends.
F-tone Networks’s FTQD- MMF Active Optical Splitter Cable is compliant with the QSFP-DD-MSA and with 200GBASE-SR4 specification. Digital diagnostics functions are available via the I2C interface as specified by CMIS V4.0. The transceiver is RoHS 2.0 compliant and lead-free per Directive 2011/65/EU.
