Avago transceiver delivers Fast Ethernet communication over POF connectors
7/28/2011 12:22 PM EDT
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.
