Avago launches Fast Ethernet transceiver for 50m (NA0.5) or 70m (NA0.3) links in harsh environments
Avago Technologies has launched a Fast Ethernet transceiver for providing reliable data transmission over plastic optical fiber (POF) link lengths up to 50m (NA0.5) or 70m (NA0.3). The AFBR-5972Z provides the ability to implement fast communication up to 100Mbps, 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 eliminates the electro-magnetic interference, crosstalk, and electrical ground problems that are common with copper wire solutions, while also providing easier, more flexible installation, says Avago. 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, the firm claims. Offering robust operation in the –40°C 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’s transmitter is based on a high-power, 650nm 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.
The AFBR-5972Z is priced at $24.18 each in 100-piece quantities. Avago provides a reference design for its implementation, as well as an application note.
