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 ℃.

Apply Solution

When optical signals are transmitted in optical fibers, they usually have certain losses. Therefore, in fiber optic networks, erbium-doped fiber amplifiers (EDFA) are required to amplify the light to compensate for the energy loss caused by insertion loss. As a very important optical amplifier device in medium and long distance fiber optic networks, EDFA has three main applications in fiber optic networks, including relay amplification, pre amplification, and post amplification, to ensure that optical signals can be transmitted for hundreds or even thousands of kilometers.
