Attenuator as a fiber optical passive devices for optical communication systems performance optical power debug, debug Fiber Instrument calibration correction, the fiber-optic signal attenuation. Use products containing the metal ions made of fiber attenuation, the optical power can adjust to the required level. Lightwit Phoconics Co., Ltd takes “Quality and Credit come first” as its base of exist and development. ISO9001 and CE assure the qualities for our customers. Firmly through quality product line, effective research, manufacture and market management and with nearly a decade accumulation on industry insight and expertise, we have forged strong ties to customers from all over the word.
