Description

DWDM Device

 Dense wavelength dividion multiplexing(DWDM) is a technology that puts data different sources together on an optical fiber, with each signal carried at the same time on its own separate light wavelength.

 

Features:

• 100GHz ITU Channel spacing

• Low insertion loss

• Wide pass band

• High channel isolation

• High stability and reliability

• Epoxy free optical path

 

Applications:

 • Channel Add/Drop

• DWDM Network

• Wavelength Routing

• Fiber Optical Amplifier

• CATV Fiber Optical System
