Industrial automation leaders choose fibre-optic module with DMI

2 May 2007 Computer/Embedded Technology

Avago Technologies' industrial Fast Ethernet optical transceivers based on the AFBR-5978Z device have been selected by Phoenix Contact and Siemens. The AFBR-5978Z is claimed to be the industry's only industrial Fast Ethernet optical transceiver to incorporate digital diagnostic monitoring interface (DMI). The DMI feature permits realtime monitoring of transceiver performance and system stability, even in cross-continent installations, resulting in higher factory network uptime.

Because of its superior immunity characteristics from electrical noise, Plastic Optical Fibre (POF) is an attractive alternative to copper in industrial and automotive automated applications. "Fibre-optic transmission has many advantages in the industrial field," said Roland Berg, senior research and development manager at Phoenix Contact. "Avago has designed its high-speed optical transceiver with superior link distances and easy device integration. Additionally, the transceiver's optimised transmission diagnostics enable us to provide customers with a world-class product for industrial networking needs."

Industrial Fast Ethernet represents an upgrade path for Fieldbus networks and other proprietary industrial networking protocols, with a speed of up to 125 MBd compared to 2 MBd for Interbus, 12 MBd for Profibus, and 16 MBd for SERCOS. It provides the open-architecture, multiprotocol interface that permits both standard and proprietary fieldbuses to interoperate. Upgrading to industrial Fast Ethernet allows devices on the factory floor to be assigned IP or MAC addresses, enabling high-speed remote diagnostics and machine sequence changes via Internet and VPN access.

Avago's AFBR-5978Z1 industrial Fast Ethernet transceiver is well-suited for high-output factory automated production lines, automotive production lines and power generation/distribution market segments.
