Compact 650nm Transceiver: AFBR-5972Z

Avago Technologies presents a Fast Ethernet transceiver that provides reliable data transmissions over plastic optical fiber (POF). The new AFBR-5972Z transceiver provides the ability to implement fast communication up to 100 Mbps and 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.

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.
