Fixed Attenautor Details
Yingda’s E2000 attenuators are compatible with Diamond brand connectors and are available in both UPC and APC versions, both being single-mode attenuators. UPC connectors are blue, and APC connectors are green.
E2000 attenuator adopt spring valve device, when the E2000 connector is plugged in, the locking mechanism will fully engage. When unplugged, the spring-loaded valve closes automatically.
The fixed attenuator e2000 is made with precise attenuation values and excellent return loss, it can effectively suppress circuit noise and isolate various other signal interferences.
Due to good repeatability, strong interchangeability, and stable and reliable performance, e2000 fixed attenuators are widely used in fiber optic distribution frames, optical communication equipment, etc.
