Abstract : A persistent problem for telephone operating companies has been low insulation resistance and noisy circuits in outdoor cross-connect terminals. This is due to impurities in condensed moisture which forms conductive bridges between nearby electrical contacts. In fact, a performance monitoring program of connectors in the outdoor environment showed that in periods of high humidity, 100 per cent of the contacts in a 25-pair connector can become noisy. So when, in 1979, a new connector system was introduced for in-building cross-connecting, special features were incorporated into the connector design with a view to outdoor operation. This paper describes these features and additional techniques which include filling the connector with a resilient gel, housing it in a moisture-shedding retainer and using a hydrophobic compound which is extruded over the cable wire ends.
