Variable Single Mode Fiber Attenuator KI7010B-APC
The KI 7010B-APC hand held Fiber Optic Variable Attenuator is a precision handheld instrument commonly used for testing single mode fiber systems with an APC connector for optical system margin and linearity. Superior specifications, high productivity and remote control capability also make this a genuine laboratory grade instrument. An additional typical application is as a passive adjustable attenuator pad in a transmission system.
- Easy to use, accurate & productive instrument
- Excellent linearity and absolute loss accuracy
- Power handling to >+30 dBm / 1000 milliwatts
- Broadband, flat λ response
- Low minimum insertion loss
- Excellent ORL & PMD characteristics
- Supplied with metal free SC, ST, LC interchangeable connectors
- Remote control (Labwindows) software
- Set attenuation is unaffected by power on/off status
- Very long battery life
