Fiber Optic Isolator Catalogue in PDF (115KB)
Fiber isolator is used in the networks to block out reflected and unwanted optic light. In fiber optic communication systems, optical light wave is reflected from any components like fiber optic connectors and receivers. In addition, scattering at the optical fiber itself and at the components that is made by optical fiber reflects light. As we know the performance of laser and optical amplifier greatly degrades if back reflected light enters these equipment. Optical light reflected back degrades the signal to noise ratio and result in the affection on the bit error rate. Fiber optic isolator is such a device to prevent the propagation of back-reflected optical light.
There is polarization maintaining fiber optic isolator, which achieve low insertion loss, high return loss and high isolation. The PM optical isolator is ideal for PM fiber amplifiers, fiber lasers and high-speed fiber optic communication systems. There are single stage and dual stage fiber isolators, with working wavelength at 1310nm,1550nm,1064mm,1480nm,and C+L band.the fiber optic isolators can be pre-installed with various kinds fiber connectors.Polarization maintaining fiber isolator features high extinction ratio & excellent environmental stability & reliability.
