AFBR-5972Z
Compact 650nm Transceiver with Compact Versatile-Link
connector for Fast Ethernet over POF
Data Sheet
Description
The AFBR-5972Z Transceiver provides the system designer
with the ability to implement Fast Ethernet (100 Mbps)
over standard bandwidth 0.5±0.05 NA POF. It features a
very compact design and has a form factor similar to the
UTP connector. This transceiver features a new compact
Versatile-Link duplex connector AFBR-4526Z and is com-
patible with existing simplex Versatile-Link connectors .
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 LVPE-
CL/LVDS 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 fiber.
Features
• Compatible to IEEE 802.3 100BASE-FX PMA using POF
PMD
• Link lengths up to 50m POF (NA0.5) or 70m POF (NA0.3)
• Compact foot print
• 3.3V operation
• LVPECL input and output data connections
• LVPECL signal detect output
• Temperature range -40°C to 85°C
Applications
• Industrial Ethernet and Fast Ethernet over polymer
optical fiber PMD
• Networking in harsh environments like factory
automation or power generation and distribution
• Supporting various Ethernet Fieldbus protocols
Receiver
The receiver utilizes a Si PIN photodiode. The PIN pho-
todiode is packaged in an optical sub-assembly, part of
the receiver section. This optical subassembly couples the
optical power efficiently from POF fiber to the receiving
PIN. The integrated IC operates at 3.3 V and converts the
photocurrent into LVPECL electrical output.
