4. SC APC Angled Polished Connector which is the Angled variety It usually has a green body Olson L Band links are only offered with SC APC and FC APC types of optical connectors The reason for this is that all analog signals transmitted over optical fibers can be seriously degraded by optical reflec tions The advantage of the APC types of connectors is that the reflections are controlled and are always very low Comparison of SC APC and SC UPC Connectors One of the most common errors encountered in the field is the use of the wrong type of connectors The most common is using SC UPC Blue Flat with SC APC Green Angled The connectors will fit together but the optical loss will be high and the performance is un predictable and unstable When Flat and Angled connectors are mated both may be per manently damaged Such damage is considered abuse and is not covered by the warranty Cleaning Optical Connectors Never clean a fiber optic connector if light is emanating from the connector Doing so may severely damage or destroy the connector Fiber optic connectors on the cable come pre terminated should be clean and capped so one can usually remove the cap and make the connection without cleaning the connector but if there is any doubt it is good practice to clean the optical connectors before making the connection Once the connection is made there should be no need clean the connector as long as the connector remains connected
