Fast Ethernet transceiver can receive LVPECL/LVDS to transmit data over POF

Avago Technologies has announced a Fast Ethernet transceiver AFBR-5972Z that provides reliable data transmissions over plastic optical fiber (POF), implement fast communication up to 100 Mbps and suitable for networking in harsh environments such as factory automation or power generation and distribution applications.

Avago says that AFBR-5972Z transceiver is an extension of its Versatile Link connector series, which eliminates the electromagnetic interference, crosstalk, and electrical ground problems that are common with copper wire solutions, while also provides easier, flexible installation.

Avago explains the features of the AFBR-4526Z transceiver, which is a small duplex connector similar to electrical RJ-45 sockets and is compatible with existing simplex Versatile Link connectors, provides operation in the -40° to +85° C extended industrial temperature range suited for industrial applications, supports various Ethernet Fieldbus protocols and is compatible with quasi-industry standard IEEE 802.3 100BASE-FX. The transceiver is more cost-efficient than comparable PROFINET industrial Ethernet standard connector solutions, claims Avago.

Avago says AFBR-5972Z device's transmitter is based on a high-power, 650-nm LED with an integrated driver that operates at 3.3V, receives a LVPECL/LVDS electrical input and converts it into a modulated current, driving the LED, this LVPECL digital interface enables a direct connection to Ethernet PHY Ics and the high-bandwidth receiver contains a PIN photodiode, packaged in an optical subassembly that couples the optical power efficiently from POF fiber to the receiving PIN.

Additional features of AFBR-5972Z include:
Link lengths up to 50m POF (NA0.5) or 70m POF (NA0.3)
Lead-free and RoHS-compliant
LVPECL signal detect output
