L-com Global Connectivity (www.L-com.com) Explains Fiber Optic Connector Types There are several types of fiber optic connectors available today. The most common are ST, SC, FC, MT-RJ and LC style connectors. All of these types of connectors can be used with either multimode of singlemode fiber. There are three types of polishes which can be applied to a fiber connector: PC or Physical contact, UPC or Ultra Physical contact and APC or Angled Physical contact. Each polish type exhibits a different level of back reflection. Back reflection is a measure of the light reflected off the end of a fiber connector. This light is measured in decibals. For certain applications, the amount of back reflection on a fiber connector is critical. View more tips and videos at www.L-com.com
