Avago - Transceiver Delivers Fast Ethernet Communication over Robust Plastic Optical Fiber Connectors

Small-Footprint Device Offers Reliable Data Transmission at up to 100 Mbps for Industrial Automation and Renewable Energy Applications

An extension of the proven Versatile Link connector series, the AFBR-5972Z transceiver eliminates the electromagnetic interference, crosstalk, and electrical ground problems that are common with copper wire solutions, while also providing easier, more flexible installation. 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 solutions. Offering robust operation in the –40° to +85° C extended industrial temperature range, the device is suitable for industrial applications and supports various Ethernet Fieldbus protocols and is compatible with quasi-industry standard IEEE 802.3 100BASE-FX.

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. The PIN photodiode is packaged in an optical subassembly that couples the optical power efficiently from POF fiber to the receiving PIN.
