Description:
Variable attenuator used in optical fiber transmission lines, continuous variable attenuation of light intensity, to reduce the product accessories, low loss, high precision adjustment, widely used in optical communication systems for various measurement systems.
A. features
Small in size and light in weight
Low insertion loss (less than 0.3dB)
Attenuation values are stable and reliable
The attenuation value is continuously adjustable in 0-30dB
No wavelength limit
B: how to use it
The adjustable attenuator must be used in conjunction with the connector. Clean the cross section with the connector before use. When in use, the connector is connected with an adjustable attenuator and tightened, and the attenuation is adjusted according to the test or use. When adjusting, loosen the lock nut first, adjust the required attenuation value of the adjusting nut, and then lock the nut tightly.
C: Notes
Adjustable attenuator must be used when the connector tightened, so as not to affect the attenuation value, transferred to the required attenuation value, must adjust the nut and lock nut locking, to prevent the required attenuation value changes. When using an adjustable attenuator, the range of use is up to 40dB attenuation. When the utility model is not used, the adjusting nut and the lock nut shall be reset to zero attenuation, and the protective cap will be protected so as to avoid the pollution of the inner ceramic sleeve.
D: storage
The adjustable attenuator can not be stored in the outdoor or seriously corrosive environment for a long time. The storage temperature is -40 DEG C, ~+85 DEG C.
Applications:
1. Telecommunication network
2. CATV networks
3. FTTx project
4. Fiber test equipment
5. Local area networks
