The 100G-SRBD (or “BIDI”) transceiver is a type of optical transceiver that can transmit and receive 100G data over a pair of multimode fibers using bidirectional technology. Like the QSFP-100G-SWDM4 transceiver, it also provides 100Gbs bandwidth over standard duplex multi-mode fiber. However, unlike the SWDM4 transceiver (which transmits 4 x 25Gbps wavelengths out of the Tx port, and receives 4 x 25Gbps wavelengths on the Rx port), each optical port on the SRBD contains both a transmitter and receiver, running at full duplex 50Gb/s over a single fiber. The two ports of the QSFP-100G-SRBD provide an aggregate 100Gb/s of bandwidth. The QSFP-100G-SRBD is supported on all Arista QSFP 100G ports, and can be used for links up to 70m of OM3 or up to 100m of OM4 multi-mode fiber.
