ABS Box-Type Dense Wavelength Division Multiplexer (DWDM)
Description
Fholink's passive dense wavelength division multiplexing equipment is a fiber capacity expansion device. It primarily utilizes wavelength division multiplexing (WDM) technology to combine multiple optical signals onto a single fiber for transmission, thereby solving the problem of fiber scarcity for users.
Fholink's 100 GHz channel spacing DWDM multiplexers/demultiplexers with 4CH/8CH/16CH channels employ thin-film filter technology and a proprietary flux-free metal welding micro-optic packaging design. They offer excellent wavelength stability and low channel insertion loss. The hermetic packaging ensures high environmental stability.
Features
- Low Insertion Loss, High Isolation
- Wide Transmission Passband, High Channel Isolation
- High Stability and Reliability
- Adhesive-Free Optical Path
Applications
- Fiber Capacity Expansion DWDM Systems
- Carrier Metropolitan Area Networks (MANs), Government and Enterprise Private Networks
- Data Center Interconnect (DCI)
