Avago Technologies (www.avagotech.com), one of the leading suppliers of analog interface components for communications, has introduced a Fast Ethernet transceiver that offers reliable data transmissions over POF (plastic optical fibers).
Featuring the ability to implement quick communication speeds of up to 100Mbps, the new AFBR-5972Z is ideal for networking in harsh environments such as in power generation and distribution or factory automation applications. Offered in a compact design, the new transceiver utilizes an Avago Versatile Link duplex connector, which enables it to reduce board footprint.
The AFBR-5972Z transceiver eliminates crosstalk, electromagnetic interference and electrical ground problems occurring within copper wire solutions, while serving as the Versatile Link connector series’ extension. It also offers a more versatile installation.
The transceiver functions best in temperatures ranging from -40° to +85° C, an extended industrial temperature range, and is more cost-efficient than Profinet industrial Ethernet standard connector solutions. Aside from being compatible with IEEE 802.3 100BASE-FX standard, the device also supports numerous Ethernet Fieldbus protocols making it suitable for industrial applications.
The transmitter of the device is anchored on a 650-nm LED that comes with a built-in driver operating at 3.3V. After receiving a LVPECL/LVDS electrical input, the transceiver transforms it into a modulated current to drive the LED, while the LVPECL digital interface directly connects it to the Ethernet PHY ICs.
The high-bandwidth receiver features a PIN photodiode packaged in an optical subassembly and efficiently couples the optical power from the POF fiber to the receiving PIN. Other features include RoHS-compliant and lead-free LVPECL signal detect output, and a maximum link lengths of 70 m POF (NA0.3) or 50 m POF (NA0.5).
