AFBR-59F1Z
125MBd Compact 650 nm Transceiver for Data
Communication over Polymer Optical Fiber (POF)
cables with a bare fiber locking system
Data Sheet
Description
The Avago Technologies AFBR-59F1Z transceiver provides
system designers with the ability to implement Fast
Ethernet (100Mbps) communication 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 eliminating the need for connectors.
This facilitates fast installation and maintenance.
The AFBR-59F1Z 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
controlled by a fully integrated driver IC. The LED driver
operates at 3.3V. It receives Low Voltage Positive Emitter
Coupled Logic (LVPECL) or Low Voltage Differential
Signaling (LVDS) differential electrical input and converts
it into a modulated current driving the LED. The 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.

Applications
• Factory automation
• Power generation and distribution system
• Industrial vision system
• Solar panel tracking system
• Home/Office Networking
Receiver
The receiver utilizes a fully integrated single chip solution
which provides excellent immunity to EMI and fast
transient dV/dt rejection. The receiver directly converts
light to a differential LVPECL output signal and operates
at 3.3V. The integrated receiver is packaged in an optical
subassembly which couples optical power efficiently from
POF to the receiving PIN.
The receiver features a signal detect (SD) output. The SD
output voltage level is LVPECL.
Package
The transceiver package contains the two optical
subassemblies, which are mounted in the housing for
bare fiber connection.
The metal shield on the bare fiber clamp transceiver
provides excellent immunity to EMI/EMC
