VARIABLE AIR GAP ATTENUATOR |
|
The Air-Gap Variable Attenuator has a ceramic alignment sleeve that provides a low insertion loss of .15dB and can be used on both multimode and Singlemode applications. Included tool provides ability to increase attenuation level to desired “level”. Device may replace mating sleeve at the patch panel, enabling variable attenuation levels to be introduced to the system. Attenuation range is 0dB to 20dB. # DESCRIPTION |
|
This Variable Attenuator uses collimator lens technology enabling the user to change attenuation through the twist of a top mounted screw. Use this variable attenuator to simulate the loss in a fiber system or testing your system’s dynamic range. A power meter and light source can be used to determine the fixed attenuation value your system requires. The attenuator has a 0.8dB typical insertion loss and is available in a 2 meter length and may be connectorized. A low back reflection style is prepared with ultra PC connectors maintaining the internal low back reflection characteristics. Attenuation range: 0.8dB to 80dB.PART # DESCRIPTION PRICE |
