We offer a variety of FC connectors to accommodate both single-mode fibers and large-core multimode fibers. The FC is a keyed connector with a 2.5mm ferrule and utilizes a threaded coupling nut. It is suitable for use in high-vibration environments. Single-mode connectors are available in PC or APC, while multimode connectors are available with either a stainless steel or ceramic ferrule with hole sizes ranging from 125µm to 1100µm. Additional hole sizes and configurations are available upon request. Below is a list of standard FC connectors available for purchase.
