FN-TRAN-QSFPDD-DR4 Fortinet Compatible 400G QSFP-DD DR4 Transceiver

As a like-for-like swap for the Fortinet part of the same number, the FN-TRAN-QSFPDD-DR4 pairs a 400G payload with a 500m single-mode reach — two traced specs that place it squarely on short intra-data-center links. It is a QSFP-DD module on the DR4 interface, terminating through an MPO-12 over single-mode fiber. It comes up on Fortinet platforms as a recognized optic, hot-swappable with no host configuration required.
