Avago Technologies' AFBR-725TMZ optical transceiver supports high speed serial links over multi-mode optical fiber at signalling rates up to 25.78 Gb/s (the seri-al line rate of 25GE). 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 IEEE 802.3by for 25GBASE-SR.

The AFBR-725TMZ is a multi-rate 850nm transceiver which ensures compliance with 25GBASE-SR specifications. Per the requirements of 25GE, internal clock and data recovery circuits (CDRs) are present on both electrical input and electrical output of this trans-ceiver. These CDRs will lock at 25.78 Gb/s. Digital diagnostic monitoring information (DMI) is present in the AFBR-725TMZ 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.
