Avago transceiver delivers Fast Ethernet communication over POF connectors

In an effort to provide reliable data transmission over plastic optical fiber (POF), Avago Technologies developed a Fast Ethernet transceiver that has the ability to implement fast communication up to 100 Mbps.

The AFBR-5972Z transceiver is suitable for networking in harsh environments such as factory automation or power generation and distribution applications. Featuring a compact design using an Avago Versatile Link duplex connector, the transceiver reduces board footprint. The transceiver's new AFBR-4526Z duplex connector is similar in size to electrical RJ-45 sockets and is compatible with existing simplex Versatile Link connectors. In addition to the smaller size, the transceiver is more cost-efficient than comparable PROFINET industrial Ethernet standard connector products, according to Avago.

The AFBR-5972Z device's transmitter is based on a high-power, 650-nm LED with an integrated driver that operates at 3.3V. The transmitter receives a LVPECL/LVDS electrical input and converts it into a modulated current, driving the LED. The LVPECL digital interface enables a direct connection to Ethernet PHY ICs. The high-bandwidth receiver contains a PIN photodiode, which is packaged in an optical subassembly that couples the optical power efficiently from POF fiber to the receiving PIN.

Key highlights:

• 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

Pricing: $24.18 each in 100 piece quantities.
