Product Description:
Wavelength Division Multiplexing(CWDM) using wavelength division multiplexing equipment will be different channel modulation signal into different wavelengths of light, and use fiber channel complex. In the receiving side, a wave separation equipment at different wavelengths of light. Wavelength Division Multiplexing (CWDM) using low cost, high bandwidth access, applies to peer-to peer, Ethernet , SONET ring, and other popular network structure, particularly suitable for short-distance, high-bandwidth, access all points of communication-intensive applications, such as building or building between the network traffic, Passive optical fiber devices typically include adapters, optical fiber activities connectors, fiber patch panels, optical attenuator, optical splitter, optical wavelength division multiplexing, optical fiber optics, and others. Lightwit Photonics company takes “Quality and Credit come first” as its base of exist and development. ISO9001 and CE assure the qualities for our customers,. Firmly through quality product line, effective research, manufacture and market management and with nearly a decade accumulation on industry insight and expertise, we have forged strong ties to customers from all over the world.
