Durable Singlemode 5db Attenuator LC / UPC For Communication System , Système de communication
Optical fiber attenuators act like sunglasses, protecting the fiber by working at a specific wavelength range.The standard for a good fiber attenuator is to absorb additional fiber instead of reflecting it.Because in communication system, it is necessary to use low optical power without damaging the optical attenuator.
