AFBR-57F5MZ optical transceiver supports high speed serial links over multi-mode optical fiber at signalling rates up to 14.025 Gb/s (the serial line rate of 16GFC). 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-5.
The AFBR-57F5MZ is a multi-rate 850nm transceiver which ensures compliance with FC-PI-5 16GFC, 8GFC and 4GFC specifications. Per the requirements of 16GFC, internal clock and data recovery circuits (CDRs) are present on both electrical input and electrical output of this transceiver. These CDRs will lock at 14.025 Gb/s (16GFC) but must be bypassed for operation at 8.5 Gb/s (8GFC) and 4.25 Gb/s (4GFC), 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-57F5MZ per the requirements of SFF-8472, providing real time monitoring information of transceiver laser, receiver and environment conditions over a SFF8431 2-wire serial interface
