FC connections

FC connectors are an optical fiber interface or fiber optic connectors that are made with a durable body and are used for environments with high vibration. This connector is usually used with both multimode optical fiber and single mode optical fiber. FC connectors are used in datacom, telecommunications, measurement equipment, and single-mode lasers. Their use is less visible today and they are replaced by SC and LC connections. The FC connection is standardized in the TIA fiber optic standard with EIA / TIA-604-4 flexibility. The FC connector was originally called a “field assembly connector” by its inventors. The name “FC” stands for “Ferrous Connection” or “Fiber Channel”.

The fiber end is embedded in a 2.5 mm ferrule made of zirconia ceramic or stainless steel. The tip is then typically polished to create a rounded surface, called lacquer. This surface specification means that when the fibers are coupled, they are placed only in the fiber blind, allowing for low-loss transmission. Fibers are routed into the reservoir for force control when the plug is controlled. A key prevents errors from occurring during fiber connections.

FC connector options

Some manufacturers consider several different grades for FC connectors. for example; An FC connector may be designated “FC/PC”, while “FC/SPC” and “FC/UPC” may indicate “super” quality.
