Fiber Optic Connectors

A FMS (Fiber Management System) manages the fiber connections from outside of fiber rack to the fiber routers. Fiber cable duct containing many fibers come from far end sites and terminate on FMS using splicing technology. FMS has fiber in and fiber out ports. From fiber out port the fiber patch will go to fiber optics based router.

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 or single mode 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.
