TN-AA-0009 An introduction of Optical Cable for HD-CCTV In order to transmit HD-SDI video signal over a long distance, optical transmitter and receiver can be easily used. Because optical cable must be used for the transmission, please refer to the below table to choose proper optical cable.   Selection of an optical cable Type Recommendation Remarks Fiber-Optic cable Single-Mode cable Multi-Mode cannot be used Connector LC type Different types of optic cable Type exterior color Connector color Single-Mode Yellow Blue Multi-Mode Orange Beige Structure of optical cable  Single-Mode cable Used in long distance transmission. Core diameter is normally 9um and color of the jacket is yellow. [Fig. 1] Structure of Single-Mode optical cable  Multi-Mode cable Core diameter is 50-100um and used in short distance transmission. Normally color of the jacket is orange. [Fig. 2] Structure of Multi-Mode optical cable 1 TN-AA-0009 Connector: LC type  Usually blue-colored connector is used for single mode cable  Usually beige-colored connector is used for multi mode cable Single-mode connector Multi-mode connector [Fig. 3] Exteriors of various LC type connectors.
