3 Channel WDM
Built to produce three optic signals with three specific light wavelengths, 3 channel WDM is often used to achieve bidirectional transmissions of voice, video and data in optical fiber communication networks. Hence, the wavelength division multiplexer is your optimum choice if you are looking for data multiplexer, audio multiplexer and video multiplexer.
Typically, this 3 channel WDM is designed to filter signals carried by lights at three wavelengths: 1310nm, 1490nm, and1550nm. The optical multiplexer also comes with filters and collimators.
The three wavelengths can be tailored per customer request. All the 3 channel WDM devices from our company have been through temperature cycle test and drop test that each lasts 24 hours. Hence, the fiber optic multiplexer can have high reliability and stability.
Benefits of 3 Channel WDM
1. Wide passband
2. Low insertion loss
3. High channel isolation
4. High stability and reliability
5. Epoxy free optical path
