Overview
The AFBR-571 Z family of optical transceivers are
compliant with the specifications set forth in the
IEEE802.3 (1000BASE-SX) and the Small Form-Factor
Pluggable (SFP) Multi-Source Agreement (MSA). This
family of transceivers is qualified in accordance with
Telcordia GR-468-CORE. Its primary application is
servicing Gigabit Ethernet links between optical
networking equipment.
The AFBR-571 Z offers maximum flexibility to designers,
manufacturers, and operators of Gigabit Ethernet
networking equipment. A pluggable architecture allows the
module to be installed into MSA standard SFP ports at any
time – even with the host equipment operating and online.
This facilitates the rapid configuration of equipment to
precisely the user’s needs – reducing inventory costs and
network downtime. Compared with traditional transceivers,
the size of the Small Form Factor package enables higher
port densities.
