QSFP-100G-SRBD Arista Compatible 100G QSFP28 BiDi 100m SMF Transceiver

100G in the QSFP28 form factor, single-fiber BiDi to 100m on a simplex LC — the Arista-coded version of exactly that is the QSFP-100G-SRBD. Running BiDi, it carries the full 100G payload over one strand at short reach, which keeps fiber count down inside the row. That single-fiber design is the draw in a dense data center aisle: 100m of reach covers rack-to-rack and leaf-to-spine hops while halving the strand count a duplex optic would demand. It comes up on Arista switching gear as a recognized module with no host configuration, hot-swapping into a live port and passing traffic the moment it seats.
