OMC's Keyed SMA (KSMA) fibre optic system launched last October is now available in all of its standard SMA diode housings.
The KSMA connector and diode receptacle system for OMC’s fibre optic transmitters and receivers deliver the rotational consistency of a keyed connector combined with the security and reliability of the SMA connector and is suitable for optically demanding and long service life applications. Thanks to the rugged, all-metal design, the connector system is robust and suits multiple applications, across many industry sectors, including industrial and consumer, transportation, medical, aerospace, petrochemical and power distribution.
The KSMA connector system features a mechanical keyway mechanism that eliminates any rotational variation when a cable is mated to the transmitter or receiver, while also featuring the same secure hexagonal lock-nut fixing found in OMC’s standard SMA connector. Ensuring there is no rotational variation between matings is useful because if a cable is disconnected and reconnected, traditional non-keyed SMA devices can rotate throughout a full 360 degrees, possibly resulting in performance variations and limiting repeatability, which can be problematic in optically-demanding applications. The lock-nut ensures that the optical fibre is held firmly in place, unlike spring-loaded connectors which can allow the fibre to move and change the attenuation of the link if the cable is subjected to any tension.
OMC’s KSMA system is now available in their H1 Bulkhead Housing, H22 PCB Mount SMA Housing, H3 Single Hole Rear Fitting Panel Mount, H11 Single Hole Front Fitting Panel Mount as well as the new VSMA (Vertical SMA) and HDMSA (high density SMA) device receptacles.
