Laser Source TW3111

Laser Source TW3111

Is a handheld optical light source, newly released in 2007. It can provide 1 to 6 wavelengths output to satisfy specific requirements including the 650nm visible light source and the 1310/1550nm wavelengths for single mode fiber or the 850/1300nm wavelengths for multimode fiber, as well as other wavelengths according to customer’s needs. Together with the TW3211 optical power meter, it is a perfect solution for fiber optic network applications.

Features

• CW, 2Hz modulation output at 650nm, and CW, 270Hz,1KHz,2KHz modulation output at other wavelengths.
• Provides 1~6 wavelengths output which can be optional according to customers’ needs
• High stability of the output power
• Stable output wavelength
• Backlight LCD display supports night operation
• Low battery power indication

Applications

Maintenance in Telecom
Maintenance CATV
Test Lab of optical fibers
Other Fiber Optic Measurements
