- 5 calibration wavelength: 1310/1490/1550/1625/1650nm
Maxwellon TF-2501 Series Optical Variable Attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for on-line testing, therefore, TF2501 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)
Application:
- Telecom/CATV Maintenance
- Comprehensive cable construction system
- Optical instruments research and development
- Optical communication education and lab testing
