QSFP28 Pluggable, Parallel Fiber-Optics Module, 128GFC Fibre Channel Application


Avago Technologies' AFBR-89FxDZ is a four-channel, pluggable, multi-mode, fiber optic QSFP28 transceiver for 128G Fibre Channel applications. The transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with each lane operating at 28.05 Gbps, giving an aggregated bandwidth of 112.2 Gbps. It allows optical interoperability up to 100m over an 8-fiber (or 12-fiber) MPO optical multi-mode OM4 cable. The pull tab facilitates the insertion and extraction of these transceivers in high density environment. Each electrical lane operates at 28.05 Gbps and conforms to 128GFC FC-PI-6P interfaces with (528,514) RS-FEC.

Per channel transmitter and receiver retimers, configured for 4x28.05G operation, can be bypassed to enable alternative data rate transmission.
