1dB-10dB Fixed Type LC/UPC/APC Fiber Optic Attenuator
Description:
Optical fiber attenuator, as a kind of optical passive device, is used to debug light power performance in optical communication system, debug calibration calibration of optical fiber instrument and attenuation of optical fiber signal. The product is made from the attenuation fiber doped with metal ions, which can adjust the optical power to the required level. When the optical transmission signal passes, the light intensity is attenuated according to the fixed value, and the light intensity requirement of the optical transmission system is reached. The optical attenuation of the single mode double window 1310NM&1550NM and the multi mode single window 850NM can be realized. High quality attenuator can withstand 1W high power optical signal for a long time. It has excellent optical performance, low polarization dependent loss PDL and stable attenuation.
The length and straightness of the core of the attenuator are strictly checked by the precision projection tester.
The fixed attenuator is made of standard high precision dust orchid. It is used in all kinds of optical fiber transmission lines, with high attenuation accuracy and stable and reliable performance. The performance characteristics are independent of wavelength changes, and can achieve dual functions of adapters and attenuators. Attenuation precision, high additional loss, low application optical distribution frame optical fiber network system, low speed optical fiber transmission system.
