Broadcom Inc. 32GFC SFP+ for Multi-Mode Optical Fiber Digital Diagnostic SFP, 850nm, 32G/16G/8G Low Voltage (3.3 V) Fibre Channel Optical Transceiver AFBR-57G5MZ

Avago Technologies’ AFBR-57G5MZ optical trans-ceiver supports high speed serial links over multi-mode optical fiber at signalling rates up to 28.05 Gb/s (the seri-al line rate of 32GFC). The product is compliant with Small Form Pluggable industry agreements SFP and SFP+ for mechanical and low speed electrical specifications. High speed electrical and optical specifications are compliant with ANSI Fibre Channel FC-PI-6. The AFBR-57G5MZ is a multi-rate 850nm transceiver which ensures compliance with FC-PI-6 32GFC, 16GFC and 8GFC specifications. Per the requirements of 32GFC, internal clock and data recovery circuits (CDRs) are present on both electrical input and electrical output of this transceiver. These CDRs will lock at 28.05 Gb/s and 14.025Gb/s (32GFC and 16GFC) but must be bypassed for operation at 8.5 Gb/s (8GFC), accomplished by using two Rate Select inputs to configure transmit and receive sides. Transmitter and receiver can operate at different data rates, as is often seen during Fibre Channel speed negotiation. Digital diagnostic monitoring information (DMI) is present in the AFBR-57G5MZ per the requirements of SFF-8472, providing real time monitoring information of transceiver laser, receiver and environment conditions over a SFF-8431 2-wire serial interface.
