Product Description
CWDM1291nm
Product Overview
CWDM stands for Coarse Wavelength Division Multiplexing, a cost-effective optical communication technology used to transmit multiple data streams simultaneously over a single optical fiber. Unlike DWDM (Dense Wavelength Division Multiplexing) which uses narrow channel spacing (e.g., 100GHz or 50GHz), CWDM typically employs wider channel spacing—most commonly 20nm—across the optical spectrum.
It works by assigning distinct, non-overlapping wavelengths to different data signals, combining (multiplexing) them at the transmission end for joint fiber transmission, and then separating (demultiplexing) them back to individual signals at the receiving end. CWDM filters, a core component of this technology, selectively pass or block specific wavelengths to enable this signal management.
Key Features
- High-Precision Wavelength Selection: Ensures the accuracy and efficiency of signal transmission to meet different optical communication requirements.
- Low Insertion Loss: Reduces the energy loss of the signal during transmission and ensures the intensity and quality of the signal.
- Excellent Channel Isolation: Effectively avoids signal interference between different channels and improves the stability of communication.
Applications
- Metro Area Networks (MANs)
- Data Center Interconnections (DCI)
- Enterprise Backbone Networks
- Fiber-to-the-X (FTTx) Systems
- Industrial Ethernet Networks
- Enterprise Campus Networks
- Small to Medium-Sized Service Provider Networks
- Surveillance and Security Systems
