Product Description

Fiber Optic Attenuator Product Name:


1 to 20 dB SC Fixed SM APC and UPC Male To Female Metal Fiber Optic Attenuator


Fiber Optic Attenuator Description:

An SC fixed male to female attenuator is a passive device used to reduce the intensity of optical signal without significantly changing the transmission wavelength.


It is a male-to-female connector and fixed-type attenuator. the attenuation can be 1 to 30dB according to your requirements. Single-mode type SC attenuator has APC and UPC polishing. The Fixed Plug-in attenuator has MPO, E2000, LC, SC, FC, ST, MU types. Metal ion bait is used to attenuate optical fiber, plug structure, easy to use, a small error, high echo value.


This product USES the patented metal ion erbium-doped fiber to effectively reduce the intensity of optical signal transmission. Compared with the optical fiber offset welding method that only changes the direction of optical transmission, the production process of this product has a significant difference in all aspects.


It is suitable for 1310-1550, C, and L bands, and can withstand the transmission of high-intensity light power over 1W for a long time, better adapting to EDFA and other high-power applications. Low polarization loss (PDL) and stable independent wavelength distribution make optical fiber attenuator an ideal choice for DWDM


Fiber Optic Attenuator Features:

  • erbium-doped metal ion attenuation fiber is adopted
  • long time to withstand high power optical signal transmission
  • 1260-1640nm bandwidth, applicable to both 1310 and 1550 wavelengths
  • attenuation range 0-30db, distinguish between standard and quality products with two different indicators


Fiber Optic Attenuator Application:


  • EDFA
  • DWDM
  • OADM
  • CATV
