Yellow Hat 30dB Metal ST Singlemode Fiber Optical Attenuator
Optical attenuator is a passive device used to reduce the power level of an optical signal. It could be applied to debug optical power performance & optical instrument calibration correction & fiber signal attenuation to ensure the optical power in a stable and desired level in the link without any changes on its original transmission wave.
Finetelecom offers LC,FC,SC,ST and MU fixed attenuator with different attenuation level, from 1dB to 30dB.
Features:
1). Low back reflection and Low PDL
2). High precision attenuation value
3). Precision control of attenuation range
4). Wide attenuation range
5). Precision ceramic ferrule
6). FC, SC, ST, LC … optional
7). Plastic or metal housing material
Application:
1). Fiber optical telecommunication system
2). Fiber optical CATV
3). Fiber optical sensor
