SAN JOSE, Calif., Aug. 4, 2011 — The AFBR-5972Z transceiver from Avago Technologies delivers fast Ethernet communication over robust plastic optical fiber connectors.

The device offers reliable data transmission at up to 100 Mb/s for industrial automation and renewable energy applications. It is suitable for networking in harsh environments such as factory automation, power generation and distribution applications. Featuring a compact design using a proprietary Versatile Link duplex connector, the transceiver reduces board footprint.

An extension of the Versatile Link connector series, the transceiver eliminates the electromagnetic interference, crosstalk and electrical ground problems that are common with copper wire solutions, while providing easier, more flexible installation.

The new AFBR-4526Z duplex connector is similar in size to electrical RJ-45 sockets and is compatible with existing simplex Versatile Link connectors.

Besides the smaller size, the transceiver is more cost-efficient than comparable PROFINET industrial Ethernet standard connectors. Offering robust operation in the −40 to 85 °C extended industrial temperature range, it supports various Ethernet Fieldbus protocols and is compatible with quasi-industry-standard IEEE 802.3 100BASE-FX.

Its transmitter is based on a high-power, 650-nm LED with an integrated driver that operates at 3.3 V. The transmitter receives a low-voltage positive emitter-coupled logic/low-voltage differential signaling (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 integrated circuits. The high-bandwidth receiver contains a PIN photodiode packaged in an optical subassembly that couples the optical power efficiently from the plastic optical fiber to the receiving PIN.

The device offers plastic optical fiber link lengths of up to 50 m with a numerical aperture of 0.5, or 70 m with a numerical aperture of 0.3. It is lead-free and RoHS-compliant.
