407-BCIB Dell Compatible 400G QSFP-DD FR4 2km SMF Transceiver

FR4 at 400G over a 2km single-mode span is the workhorse reach for spine-to-leaf and intra-facility 400G links, and that distinctive combination defines the 407-BCIB. It is a 400G QSFP-DD carrying FR4 across duplex LC single-mode fiber to 2km, seated in a standard QSFP-DD cage on Dell switching. The module is coded so Dell gear brings it up as a recognized part with no host configuration, and it reports live optical telemetry over DDM. The 2km FR4 profile targets data-center and campus 400G aggregation where an SMF pair replaces a costlier long-reach optic.
