Description
Features of MEMS Variable Attenuator
- Reliable performance, stable attenuator technical indicators meet industry standards;
- All-fiber structure, good environmental stability, low polarization-related loss;
- Different styles of connectors SC LC FC ST SMA, etc;
- Can effectively suppress ground loop noise and eliminate interference;
- Effectively isolate from the main control end in electricity to prevent accidental damage to the main control end;
- Plug-in times greater than 10,000+, good flame retardancy, reaching UL94V0, high temperature resistance and environmental protection, compliant with ROHS requirements, and high impact resistance.

MEMS Variable Optical Attenuator Details
MEMS variable optical attenuator are widely used in cable television systems to meet the level requirements of multiple ports, we can use the middle adjustment button to adjust the input and output pigtails attenuation value to your required level from 0 -30dB variable.
Yingda support add various types of fiber optic connectors, SC LC FC ST SMA with UPC, APC, PC endface. It is suitable for single mode and multimode fiber. Please specify your needs before buying. Singlemode cable is yellow jacket, multimode cable is orange, beige or purple jacket. FC UPC is black connector, while FC APC is green connectors like below:
Yingda provide safe package for every fiber optical attenautors as below, which can hold the connectors, switch, and cable in place without loosing after long time transportation.
We make production according to ISO 9001 management system, will test all finished fiber optical attenuators during or after production. And you can check the test data on the test report which will be with the finished products. Any more questions, please consult our sales team.
