Variable Single Mode Fiber Attenuator KI7010B
The KI 7010B hand held Fiber Optic Variable Attenuator is a precision handheld instrument commonly used for testing single mode fiber systems 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
