Product details for ST Fiber Optic Attenuator

ST fiber optic attenuator includes st single mode female to male and female to female fiber optic attenuator from 1dB to connect st fiber optic pigtail or patch cables to reduce the power of signal at a certain attenuation.

ST fiber optic attenuator features high power endurance and low back reflection. ST Fiber Optic Attenuators are used in communication systems to reduce optical power launched onto the photo detector. These high performance devices are designed to give accurate attenuation over a wide range of wavelengths. The plug type configuration allows them to be used directly on the end of a patch cord, which in turn can insert directly into an adaptor.

ST Fiber Optic Attenuators is one kind of optical passive device which is used to debug the performance of the optical power in the optical communication system,debugging fiber optic instrument calibration correction, optical signal attenuation. And used for the attenuation of the input optical power, avoid optical receiver distortion due to input optical power powerful. Applications of the ST fiber optic attenuators include CATV networks, data communication and telecommunication networks. ST fiber attenuators are used inline to reduce the fiber optic power by a certain fixed value. They are high attenuation accuracy and working temperature from -40 C to +75 C. Our ST fiber optic attenuators are made according to industrial standards.
