The Avago Technologies AFBR-79EBMZ is a 40 GbE QSFP+ pluggable transceiver with four 10.3125 Gbps lanes, supporting up to 100 m OM3 and 150 m OM4 fiber.
The AFBR-79EBMZ transceiver provides four electrical data lanes per direction that are multiplexed into two 20 Gb/s optical channels over a single LC duplex fiber. It complies with the 40GE XLPPI electrical specification and QSFP+ SFF‑8436 mechanical standard, offering hot‑pluggable operation and a two‑wire serial (TWS) management interface.
Key specifications include 10.3125 Gbps per electrical channel, 3.5 W power consumption, and support for OM3 (100 m) and OM4 (150 m) multimode fiber at 850 nm/900 nm wavelengths. The module also provides real‑time digital diagnostic monitoring for temperature, voltage, laser bias, and optical power, enabling predictive failure identification and fault isolation.
