USD Call for Quote


GAOTek Fixed Optic Attenuator 5 dB (Portable ST-ST Air Gap) is designed to be used in CATV equipment as in-line to reduce the fiber optic power by a certain fixed value with simplex fiber type. The optic attenuator consist of both UPC ST and APC ST fiber optic attenuators used for single mode applications which are within 1240 nm to 1620 nm compatible working wavelength, including the 1310 nm and 1550 nm typical single mode wavelength.  It provides high attenuation accuracy with an attenuation range from 1 dB to 30 dB. These ST fiber attenuators are equipped with ceramic sleeves and have a high quality which enables it to last for a longer lifetime.


  • Attenuation range from 1 dB to 30 dB
  • Compatible working wavelength range: 1240 nm to 1620 nm, typical single mode wavelength: 1310 nm and 1550 nm
  • Industry standard attenuation levels and Multiple attenuators per kit
  • Portable and durable with a small, durable case for easy portability.
  • Compartmentalized case provides safe component storage and simple organization.
