HDK-55 1206 VER1 (U) 105TROUBLE SHOOTING and MAINTENANCE66.4 Cleaning Camera Connectors6.4 Cleaning Camera ConnectorsThe fiber cable connecting the camera and the BS transmits optical signals through 10μm core glass fibers. If Ferrules, whichsecure glass fibers, are dirty or have dust on them, transmission loss (optical signal attenuation) occurs. If Ferrules are extremelydirty, optical signals are interrupted and the fiber cable may not work properly. Regular cleaning of Ferrules is suggested if thecamera connector is frequently removed and inserted. The figures below show the shape of the camera connector joint section,location of the Ferrules, and how to clean the Ferrules:Camera Connector Joint SectionOPS SeriesFerrulesScrew: Hole only for maleconnectorsTop: Present only infemale connectorsPlug (female) Top FerruleFerruleFerruleFerruleFerruleFerruleFerrulesPlug (male)Receptacle (female)Receptacle (male)SMPTE typeTopTopTopPlug (female)Plug (male)Receptacle (female)Receptacle (male)FerruleFerruleFerrulesTop: Present only infemale connectorsAlignment sleeve Alignment sleeve:Present only in femaleconnectorsAlignment sleeveAlignment sleeveMale and Female Camera ConnectorsReceptacle (female) Plug (male)Plug (female)BSF-55 rearHDK-55Receptacle (male)
