Ultra low Loss VOA In-line Variable Optical Attenuator
GEZHI's VOA is tuned to a micrometric screw which allows an excellent repeatability with a wide attenuation range from 0.6 to 60dB. Its also with a ultra low loss than 0.6dB with 1310nm or 1550nm +/-40nm. The Optical Variable Attenuators provided by GEZHI Photonics Co.,Ltd has been designed to be used within the context of telecommunications and instrumentation applications. However, beyond those areas, our band held product leads to other various applications.
Furthermode, GEZHI can provide fixed attenuators. Those attenuators were designed to a technique entirely based on optical fibers which allows a very good behaviour towards power. Also customized VOA is available like Multimode VOA, MEMS VOA, High Power VOA etc.
