Optical Isolator

An optical fiber isolator is a passive device that allows the propagation of the one-way light waves and that is sufficiently isolated from reflected light to improve the transmission efficiency of light waves. Apply to erbium doped fiber amplifier, the performances and technical applications of theoptical isolator in detail. An optically isolated passive device made by Vsunlight is a passive device that transmits high-frequency signal energy in one direction in one direction, ensuring that light travels in only one direction. It is characterized by small forward insertion loss, high reverse isolation and high return loss. All versions are designed for use in an outdoor nvironment within a temperature range of –10 ℃ to +70 ℃.

Fiber Array

Fiber Array, referred as to: FA. The optical coupling component that is between the optical waveguide and the devices. Using sophisticated optical fiber assembly process to reach accurate positioning so that thermal expansion coefficient matching assembly designed to ensure the fiber array base plate no stress. After 200 hours of high and low temperature reliability experiment, accurate port plane angle, align the chip accurately; and polish plane comes bright and clean. Vsunlight self-produced fiber array provides a variety of options, such as the channelnumber of fiber array, core spacing and grinding angle. It is widely used in planaroptical waveguide (PLC), arrayed waveguide grating (AWG), Active array opticaldevices in different fields such as MEMS and so on .

Optical Circulator

An optical circulator is a unidirectional three-port device with irreversible transmission that allows light to travel in a specific direction. According to their physical principles, circulators can be divided into non-polarization-maintaining circulators and polarization-maintaining circulators. The Vsunlight Tri-Port or four-Port Optical Circulator is a passive device that transmits high-frequency signal energy in one direction, ensuring that light travels in only one direction. It has the characteristics of low insertion loss, high isolation, and low polarization-related loss. The product has stable performance and strong reliability. All versions are designed for use in an outdoor environment within a temperature range of –10 ℃ to +70 ℃.
