| Description
Fiber optic attenuator is mainly applied in adjustment of optical power, calibration of fiber optic instrument and attenuation of fiber optic signal during the fiber optic communication system. It adopts attenuation fiber with metal ion doped. It can adjust the optical power to certain level as required. There are two main types
1, Female to Male fiber optic attenuator (OPATT-3000-SC/LC/ST)
2, In-line fiber optic attenuator (OPATT-3000-IA)
Feature
1 compliant with ANSI.TIA/EIA and IEC standards
2) One piece housing construction
3) Metal-ion doped fiber
4) Wavelength attenuation stability
5) Low back reflection
6) Low attenuation tolerances
Application
1) Fiber optic distribution frame
2) Fiber optic network system
3) High-speed fiber optic transmission system
4) Trunk DWDM system
5) OADM
