Transmitter/receiver components for industrial optical fibre systems

July 16, 2014 // By Graham Prophet
A robust and low cost Tx/Rx family of parts for use with polymer and large-core glass fibre systems employs precision-machined metal components to ensure device suitability for industrial environments.

OMC's H19 range features a precision-machined metal ferrule which provides enhanced reliability for industrial applications. The range includes both single channel devices for use with simplex fibre and dual channel devices with duplex connectors facilitating transceiver operation.

Most connector systems for use with polymer fibre are produced almost entirely out of plastic, including the ferrule that attaches to the fibre. This provides a lower cost solution over metal connector systems, but can lead to reduced robustness and resilience when used in long-term industrial applications or other demanding environments.

OMC’s H19 package benefits from the cost advantages of a high quality plastic housing, but the design incorporates a precision-machined metal ferrule which provides a much higher level of precision and ruggedness over plastic-ferruled systems. The connector body also features twin metal side plates which allow a four-point mechanical solder connection to the circuit board. This provides a much stronger and more secure mechanical connection than typically found in plastic-bodied parts and further enhances the device’s reliability in industrial applications, both through added vibration resistance and by minimising mechanical strain to the electrical solder joints.

The H19 is designed predominantly for use with polymer fibre systems but can also be used with large-core glass fibre should extended range be required. Any of OMC’s transmitter or receiver diodes can be housed in the H19 package, providing considerable versatility to designers.

OMC offers a range of transmitter/receiver parts as standard products, and can house diodes in a variety of housings and connector systems to provide the most appropriate solution for each application. The company also specialises in re-engineering obsolete transmitter, receiver and connectors to support legacy systems requiring maintenance or refurbishment.
