FC Variable Optical Fiber Attenuator (VOA)
We supply various fiber optic attenuators to reduce the optical power at a certain level.  

Features 
1. High attenuation and environmental stability
2. Compliant with TIA/IEA, IEC 60869-1, RoHS
3. Low back reflection, low PDL, low insertion loss
4. High power endurance, wavelength independent
5. Precise control of attenuation range from 1 to 30dB

Applications
1. DWDM, EDFA (Erbium Doped Fiber Amplifier)
2. FTTH, Gigabit Ethernet , GPON , EPON
3. Telecommunication and fiber optic data transmission networks
4. Wide Area Networks (WAN), Local Area Network (LAN), CATV Network
