400G QSFP56-DD to 4x100G QSFP56 MMF Active Optical Splitter Cable

Description
F-tone Networks’s FTQD-4H-4Q5-Oxxx MMF Active Optical Splitter Cable is used in 4 X 100 Gigabit Ethernet links over OM3/OM4/OM5 multimode fiber, which provides connectivity between system units with a 400GbE connector on one side and four separate 100GbE connectors on the other four 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-4H-4Q5-Oxxx MMF Active Optical Splitter Cable is compliant with the QSFP-DD-MSA and with 100GBASE-SR2 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.
