AFBR-59F3Z
Compact 650 nm Transceiver for 1 Gbps Data communication
MLCC (Multilevel Coset Coded) over POF (Polymer Optical Fiber)
Data Sheet
Description
The Avago Technologies' AFBR-59F3Z transceiver pro-
vides system designers with the ability to support serial
communication to data rates of one Gigabit over 2.2 mm
jacketed standard Polymer Optical Fiber (POF).
The innovative bare fiber locking mechanism of the
transceiver allows connection of POF cable with a simple
insert-and-lock system; no connectors are required. This
enables very fast installation and maintenance. This very
compact designed Laser Class 1 product is UL listed, lead
free and compliant with RoHS. The form factor is similar to
the well known RJ-45 connector.
Transmitter
The transmitter contains a 650 nm LED, which is driven by
a fully integrated driver IC. The LED driver operates at 3.3
V. The IC is a linear integrated LED driver with differential
input signals. It converts the input voltage linear in an out-
put current for the LED. The driver needs an active Power-
Enable signal for active current output. With a Low signal
on the PowerEnable pin, the driver is set to power-saving
state. LED and IC are packaged in an optical subassembly.
The optical subassembly couples the optical output pow-
er over a optic lens efficiently into the POF fiber.
Receiver
The receiver device utilizes an integrated fiber optical
receiver offering an integrated PIN photodiode together
with the necessary amplifiers, which provide direct con-
version of light to differential analog output signal.
Receiver circuitry provides an analog receive power moni-
tor output proportional to the amount of optical light at
the receiver.
The integrated receiver is packaged in an optical subas-
sembly. This optical subassembly couples the optical
power efficiently from POF fiber to the receiving PIN. The
integrated IC operates at 3.3V.
The receiver can be set into a power-saving state by ex-
ternally forcing the monitoring pin to a voltage above a
threshold.
