Avago accelerates ethernet communication in harsh environments
The company’s new compact transceiver, which incorporates a phosphide based 650nm LED and other III-V compound semiconductor components, offers reliable data transmission of up to 100 Mbps.
Avago Technologies, a supplier of analogue interface components for communications, industrial and consumer applications, has revealed a fast ethernet transceiver that provides reliable data transmissions over plastic optical fibre (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.
AFBR-5972Z Fast Ethernet transceiver
An extension of the 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, Avago says 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 fibre to the receiving PIN.
With link lengths up to 50m POF (NA0.5) or 70m POF (NA0.3), the module is lead-free and RoHS-compliant and has LVPECL signal detect output.
The AFBR-5972Z Fast Ethernet transceiver is priced at $24.18 each in 100 piece quantities. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.
