AFBR-5972EZ, AFBR-5972BZ
Compact 650nm Transceiver with Compact Versatile
Link Connector for Fast Ethernet over POF
Data Sheet
Description
The AFBR-5972xZ transceivers provide system designers
with the ability to implement Fast Ethernet (100 Mbps)
over standard bandwidth 0.5±0.05 NA POF. The new com-
pact Versatile-Link duplex connector is compatible with
existing simplex Versatile-Link connectors and features
a very compact design with a form factor similar to the
UTP connector. To enable easy visual differentiation the
AFBR-5972EZ uses standard black port color while the
AFBR-5972BZ has a blue colored port. The AFBR-5972xZ
transceivers are lead free and compliant with RoHS.
Transmitter
The transmitter contains a 650nm LED with a driver IC. The
LED driver operates at 3.3V. It receives an LVDS electrical
input, and converts it into a modulated current driving the
LED. IC and LED are packaged in an optical subassembly,
part of the transmitter section. The optical subassembly
couples the output optical power efficiently into POF fi-
ber.
Receiver
The receiver utilizes an amplifier/quantizer IC with an inte-
grated double photodiode. The IC is packaged in an opti-
cal sub-assembly, part of the receiver section. This optical
subassembly couples the optical power efficiently from
POF fiber to the receiving photodiode. The integrated IC
operates at 3.3V and converts the photocurrent into LVDS
electrical output.

Package
The transceiver package consists of three basic elements;
two opto-electical subassemblies and the housing as il-
lustrated in the block diagrams in figure 1. The package
outline drawing and pin-outs are shown in figures 2 and 7.
