850nm PM Fiber Mirror Reflectors are used to reflect the light emerging from a fiber back in the reverse direction. They are used to build fiber interferometers, or with fiber fused splitters to measure back reflection within fiber optic components. They can also be used to measure the sensitivity of sources to back reflection from other devices, by providing reference reflection levels. This is very useful for deriving back reflection specifications for transmitters.

PM Fiber Mirror Reflector consist of a PM fiber optic collimator and a mirror. The design reflectivity of the mirror itself is >99%, but due to the insertion loss of the fiber coupling of the collimator, we distinguish several mirrors with different reflectivity.

Performance Specifications

1. Above specification are for device without connector, and may change without notice.
2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. Power transmits through the connector less than 2W. The default connector key is aligned to slow axis.
