The FN-CABLE-QSFPDD-2QSFP56-LB5 is the longer-reach 400G-to-2x200G breakout DAC at 2.5 metres, letting a fan-out cross into a neighbouring rack. One QSFP-DD connector serves the 400GbE breakout port; two QSFP56 tails feed 200GbE ports. The optics are integrated and Fortinet-qualified, so every end clears the appliance’s compatibility check, and the whole split stays on low-power passive copper.

At 2.5m this breakout carries a 400G-to-2x200G fan-out across adjacent racks, so one QSFP-DD port on a flagship FortiGate can feed two 200G QSFP56 devices a short distance away. It is the reach step up from the 1m FN-CABLE-QSFPDD-2QSFP56-L1 while still staying inside passive copper’s range.
The QSFP-DD end needs a 400GbE port in 2x200G breakout mode; the two QSFP56 ends go into 200GbE QSFP56 ports. For same-rack fan-out use the 1m FN-CABLE-QSFPDD-2QSFP56-L1. For an 8x50G split, use the FN-CABLE-QSFPDD-8SFP56 cables; for a straight 400G link, the FN-CABLE-QSFPDD-DAC-B5.
