1. 1310nm/1550nm dual-wavelength, single output 2. CW output and 2kHz modulated wave output 3. Durability, handheld

Summary:

GS-20 series of dual-wavelength light source provides fiber optic test with stable and accurate power output, It offers only one interface for 1310nm/1550nm output. It tests the long-distance and local SM optical fiber system exactly and quickly, it can also measure the loss of fiber in cooperation with GP power meter.

Features:

Durability, pocket type is easy to carry.1310nm/1550nm dual-wavelength, single outputPrompt and power off automatically when low-voltageCW output and 2kHz modulated wave output

Routine Maintenance:

Please keep the fiber connector clean before testing. Cover the fiber connector visor after using the device.When out of service for a long period, please remove the battery in order to avoid battery decay. (Please use rechargeable battery properly when the rechargeable device working. Non-rechargeable battery is forbidden, which may cause explosion. )External Power Supply need to be used with the accessory and the matching products, for fear that the permanent damage may be caused.Do not make the light get into eyes directly at the working condition, it may cause the permanent damage of eyes. Do not disassemble the device, it may cause the permanent damage and lose guarantee qualification.
