Amphenol Fiber Systems international (AFSI) offers the ARCH Series TFOCA-II® Ruggedized Media Converter to provide optical-electrical (O-E) and electrical-optical (E-O) conversion for harsh environments. This stand-alone unit features ruggedized optical transceivers integrated into a compact housing with 10/100/1000 Ethernet electrical interfaces (additional electrical interfaces available-consult factory) and AFSI’s TFOCA-II® connector.

The “plug and play” unit allows systems engineers to effortlessly convert their systems to take advantage of the benefits of fiber optics without the need to design and develop harsh environment fiber optic transceivers and associated electronics. Also, the ARCH TFOCA-II® Ruggedized Media Converter’s compact size significantly reduces the footprint devoted to O-E and E-O conversion using discrete components. The standard TFOCA-II® Ruggedized Media Converter supports conversion for 10/100/1000 (auto adaptable) Ethernet providing up to 1.0Gb/s transport over 10 miles using single mode fiber. The unit incorporates AFSI’s TFOCA-II® field-proven connector (US Army standard fiber optic connector) with hundreds of thousands of units deployed. The rugged four-channel TFOCA-II® is hermaphroditic, allowing the user to easily concatenate cable assemblies in the field to meet the required length.
