OMC has launched its H19 range of low-cost optical transmitter/receiver devices for polymer and large-core glass fibre systems, featuring a precision-machined metal ferrule that provides enhanced reliability for industrial applications.

H19 package

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.

According to OMC, the H19 package benefits from the cost advantages of a high-quality plastic housing, but the design incorporates a precision-machined metal ferrule that provides a much higher level of precision and ruggedness over plastic-ferruled systems.

Key features and benefits

  • The connector body features twin-metal side plates that allow a four-point mechanical solder connection to the circuit board. This provides a 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.
  • According to OMC commercial director William Heath, the H19 series is designed to benefit applications that combine the contrasting requirements of low cost and high reliability and robustness. He said: ‘Engineers can choose the transmitter and receiver devices that suit their system design, or we can calculate the optical budget for their system and suggest the appropriate parts.’
  • Heath added: ‘Using our proprietary Active Alignment technology, we can also produce the devices to specific electro-optical performance windows as required by each customer’s application.’
