BoxOptronics 1310nm 1550nm L-Band Polarization independent Optical Isolator is a fiber-coupled in-line polarization-independent isolator that Fiber isolators protect light sources from back reflections and signals that can cause intensity noise and optical damage. Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light in the forward direction while absorbing or displacing light propagating in the reverse direction, It is widely use in protect against reflections, which can corrupt some measurements or damage lasers and amplifiers. This 1310nm 1550nm L-Band Polarization independent Optical Isolator can be single or double/dual stage depending on the degree of required optical isolation of the propagating light.
