1310nm SFP+ Optical Transceiver Module for 16G/8G/4G/2G Fibre Channel


The Avago AFCT-57F3xxMZ is an optical transceiver module that supports high speed serial links over single mode optical fiber at signalling rates up to 14.025 Gb/s (the serial line rate of 16 GFC). 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 AFCT-57F3xxMZ is a multi-rate 1310nm transceiver which ensures compliance with FC-PI-5 16 GFC, 8 GFC and 4 GFC specifications. Per the requirements of 16 GFC, an internal clock and data recovery circuit (CDR) is present on the electrical output of this transceiver. The CDR will lock at 14.025Gb/s (16 GFC) but must be bypassed for operation at 8.5Gb/s (8 GFC) and 4.25Gb/s (4 GFC), accomplished by using 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 AFCT-57F3xxMZ 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.
