Product Description

Polarization Maintaining In-Line Attenuator Optical Attenuators use for Communication Systems

Product Description

A fiber optic attenuator(VOA) , also known as an optical attenuator, is a device that reduces the power level of an optical signal in a fiber optic network or in free space. Attenuators are often used to prevent a signal from being too strong for the receiver, which could overpower the receiving elements or degrade the network's bit error ratio. They can also help achieve the best performance for the fiber optic system.

Features:

• Low PDL
• High stability and reliability
• High Precise attenuation value
• Low Polarization Dependent Loss
• Flawless end face Wide attenuation range (variable)

Applications:

• Fiber Sensors
• FTTH, CATV, LAN
• Fiber Optical Laser
• Optical Fiber Communication
