Cisco QSFP-100G-SRBD Compatible 100G SR-BiDi QSFP28, Duplex LC MMF

EdgeOptic's QSFP-100G-SRBD compatible is a Cisco-coded 100G SR-BiDi version of the EdgeOptic multi-vendor 100G BiDi transceiver, programmed with Cisco-recognized EEPROM so Cisco switches accept it as a native module. It is the 100G single-rate part. Don't confuse it with the QSFP-40/100-SRBD, which is the dual-rate 40G and 100G sibling sold under its own part number.

The module carries 100 Gigabit Ethernet over a pair of multimode fibers in a QSFP28 housing with a duplex LC connector. Four 25G NRZ electrical lanes per direction map to two 50G PAM4 optical lanes for an aggregate 100 Gbps. One strand transmits at 850 nm and the other at 900 nm, while a wideband receiver spanning 832 to 918 nm reads both channels. Reach is 70 m on OM3, 100 m on OM4, and up to 150 m on OM5, derived from the 1.9 dB average link budget against typical multimode cabling attenuation.

Because the receiver is wideband and the link uses a standard duplex-LC TX-to-RX crossover, the same QSFP-100G-SRBD part goes in both ends. There is no separate far-end variant to pair with it. The transmitter uses VCSEL lasers, the receiver uses PIN photodiodes, and the module reports DOM diagnostics for live monitoring of temperature, bias, and optical power. Host-side Forward Error Correction is required to close the link. Operating range is 0 to 70 deg C.

The QSFP28 host electrical interface follows IEEE 802.3bm (CAUI-4); the SR-BiDi optical scheme itself is a vendor and MSA specification rather than an IEEE-standardized PMD. The part works on Cisco Nexus 9000 and Nexus 3000 platforms; verify the chassis transceiver table for your software release before deployment. EdgeOptic Cisco-coded optics present Cisco-recognized identifiers, so the service unsupported-transceiver command is not needed.
