AFBR-59F2Z
250MBd Compact 650nm Transceiver for
Data communication over Polymer Optical Fiber
(POF) cables with a bare fiber locking system
Data Sheet
Description
The Avago Technologies AFBR-59F2Z transceiver provides
system designers with the ability to support serial com-
munication with baud rates of up to 250MBd over 2.2mm
jacketed standard polymer optical fiber (POF).
The innovative bare fiber locking mechanism of the trans-
ceiver allows connection of POF cable with a simple insert
and lock system eliminating the need for connectors. This
facilitates fast installation and maintenance.
The AFBR-59F2Z is Laser Class 1, lead-free and compliant
with RoHS. The very compact design is similar to that of
the well known RJ-45 connector.
Transmitter
The transmitter consists of a 650nm LED which is con-
trolled by a fully integrated driver IC. The LED driver oper-
ates at 3.3V. It receives Low Voltage Differential Signaling
(LVDS) electrical input, and converts it into a modulated
current driving the LED. LED and driver IC are packaged in
an optical subassembly.
The optimized lens system of the optical subassembly
couples the emitted optical power very efficiently into
1mm core POF cable.

Receiver
The receiver utilizes a fully integrated single chip solution
which provides excellent immunity to EMI and fast tran-
sient dV/dt rejection. The receiver directly converts light
to a digital LVDS output signal and operates at 3.3V nomi-
nal supply. The integrated receiver is packaged in an opti-
cal subassembly, which couples optical power efficiently
from POF to the receiving PIN.
The receiver features an analog monitor output of the
incoming optical signal. The monitor output provides an
analog voltage proportional to the average optical input
power. In absence of receiver optical input signal, the
receiver is in low power sleep mode and the differential
output signal is pulled to ground. The receiver wakes up,
when a valid optical input signal is detected.
Package
The transceiver package contains the two optical subas-
semblies which are mounted in the housing for bare fiber
connection.
The metal shield on bare fiber clamp transceiver provides
excellent immunity to EMI/ EMC
