Fiber Optical Isolator Mini Polarization Independent In Line
Isolator 1310nm
The polarization-independent in-line isolator including 1310, 1450,
1480, 1550, 1580, 1610, 1650nm is a passive optical device that
only allows one-way light to pass through. Its working principle is
based on the non-reciprocity of Faraday rotation. The light
reflected by the optical fiber echo can be well isolated by the
optical isolator. Optical isolators mainly use the Faraday effect
of magneto-optical crystals. It is a passive device that allows
light to pass in one direction but prevents it from passing in the
opposite direction. Its function is to limit the direction of light
so that light can only be transmitted in one direction. The light
reflected by the optical fiber echo can be very good by the optical
isolator. Isolation improves the efficiency of light wave
transmission. This product uses a mini-size package and is used in
some highly integrated optical modules, which very well fills the
gap in this regard.
