AFBR-5978Z
Digital Diagnostic 650nm Transceiver for Fast Ethernet
(10/100 Mbps) with SC-RJ connector
Data Sheet
Description
The AFBR-5978Z transceiver provides the system
designer with the ability to implement Fast Ethernet
(100 Mbps) or Ethernet (10 Mbps) over 50 meter
standard bandwidth 0.5±0.05 NA POF and 100 meter
standard bandwidth 0.37±0.04 NA HCS fiber. The
connectivity available for the transceiver is SC-RJ. This
product is lead free and compliant with RoHS.
Transmitter
The transmitter contains a 650nm LED with an
integrated driver. The LED driver operates at 3.3 V. It
receives a LVPECL compatible electrical input, and
converts it into a modulated current driving the LED.
The LED is packaged in an optical subassembly, part
of the transmitter section. The optical subassembly
couples the output optical power efficiently into POF
or HCS fiber.
Receiver
The receiver utilizes a Si PIN photodiode. The PIN
photodiode is packaged in an optical sub-assembly,
part of the receiver section. This optical subassembly
couples the optical power efficiently from POF or HCS
fiber to the receiving PIN. The integrated IC operates
at 3.3 V and converts the photocurrent into LVPECL
compatible electrical output.
Package
The transceiver package consist of four basic elements;
two optical subassemblies, an electrical subassembly
and the housing as illustrated in the block diagrams in
Figure 1. The package outline drawing and pin out are
shown in Figures 2 and 3.
