Fibre Channel RoHS Compliant Optical Transceiver
Data Sheet
Description
Avago Technologies’ AFBR-54D7APZ optical transceiver
supports high-speed serial links over multimode optical
fiber at signaling rates up to 8.5 GBd. Compliant with Small
Form Pluggable (SFP) Multi Source Agreement (MSA) elec-
trical specifications for duplex transceivers, ANSI Fibre
Channel for FC-PI-4 and FC-PI-2 for gigabit applications.
The part is electrically and mechanically interoperable
with Mini SFP compliant applications.
The AFBR-54D7APZ is a multi-rate 850nm SFP which
ensures compliance to 8.5/4.25/2.125 GBd Fibre Channel
specifications without the need for Rate Select. The AFBR-
54D7APZ will ignore both Rate Select pin and control bit
inputs (ie. no connect inside the SFP). This simplifies Fibre
Channel host auto-negotiation algorithms, layout and
software.
As an enhancement to the conventional SFP interface
defined in SFF-8074i, the AFBR-54D7APZ is compliant to
SFF-8472 (digital diagnostic interface for optical trans-
ceivers). Using the 2-wire serial interface defined in the
SFF-8472 MSA, the AFBR-54D7APZ provides real time
temperature, supply voltage, laser bias current, laser
average output power and received input power. This
information is in addition to conventional SFP base data.
The digital diagnostic interface also adds the ability to
disable the transmitter (TX_DISABLE), monitor for Trans-
mitter Faults (TX_FAULT), and monitor for Receiver Loss of
Signal (RX_LOS).
The mini SFP form factor narrows the optical centerline
of a conventional SFP from 6.25mm to 5.25mm in order
to increase port densities in target applications. A mini
SFP is compatible with dual simplex LC connectors and
non-standard duplex LC connectors locked to a 5.25mm
centerline. Mini SFP module widths are 11.5mm vs. the
standard SFP+ width of 13.55mm, requiring a new recep-
tacle cage but remaining interoperable with the standard
SFP+ 20 pin electrical connector.
