DWDM Passive Coarse Wavelength Division Multiplexing Equipment
Product Overview
Fholink's DWDM Passive Dense Wavelength Division Multiplexing equipment is a fiber capacity expansion solution. By adopting DWDM technology, it multiplexes 2 to 32 optical signal channels onto a single fiber for transmission, effectively addressing fiber resource scarcity for users.
Fholink passive WDM equipment is widely used in carrier networks, government and enterprise private networks, and data centers.
Product Features
1. Low insertion loss and high isolation
2. Low polarization-dependent loss with high stability
3. Customizable channel configurations, supporting 2 to 32 wavelengths
4. Diverse packaging options, primarily including 1U rack-mounted and ABS box types
