Any source of back-reflection can be a major cause of bit errors. Fiber optic terminators prevent the reflection of light and minimize optical back reflections in fiber systems that deploy switches, couplers and Wave Division Multiplexers.

They are designed for use in unused ports and each connector is environmentally sealed for protection.
