Product Description
OptoNest's optical attenuators are available with flat attenuation properties. OptoNest's optical attenuators are designed for the use from 1200nm to 1650nm without any significant variation in dB and thus the uniform attenuation spectrum is ideal for WDM applications.
Applications
- Fiber Optic Telecommunications
- CATV Systems
- EDFA
- Optical Network Equipments
- Bi-directional Systems
