Passive CWDW Solutions

CWDM (Coarse Wavelength Division Multiplexer) is a sparse wavelength division multiplexer, also known as a coarse wavelength division multiplexer. CWDM has 18 different wavelength channels, and the different wavelengths of each channel are separated by 20nm, using wavelengths from 1270 nm to 1610 nm. Because it is compact and cost-effective, making it an ideal solution for short-range communications. The biggest advantage of the CWDM system lies in its low cost, and the device cost is mainly reflected in filters and lasers.

 

The wide wavelength interval of 20nm also brings to CWDM the advantages of low technical index requirements for lasers and the simplified structure of optical multiplexer/demultiplexer.

 

 

The constant need to increase the bandwidth of optical transmission lines is a significant problem for most network operators. Besides that it takes serious financial costs, the laying of new fiber optic cables often is associated with the physical impossibility it to be done in short terms. In order to find an adequate response to overcome this problem Gracy Fiber offers solutions for spectral multiplexing in optical transmission systems, based on passive CWDM technology. These solutions are compatible with the modern active network equipment and allow multiplexing of different traffic flows like 10/100/1000/10G/100G Ethernet, SDH (STM 1/4/16/64), ATM, ESCON, Fibre Channel, FTTx and CATV over one or two optical fibers.

 

 

We use different CWDM multiplexers, which can support up to 18 optical signals on a pair of optical fibers or up to 9 optical signals on а single optical fiber. In our projects, we implement different types of CWDM equipment that are designed to support a broad range of network topologies, ranging from scalable point-to-point links to single or dual fiber-protected rings.

1. Wavelength Multiplexing: CWDM employs different wavelengths of light (typically in the 1270 nm to 1610 nm range) to transmit multiple data streams over a single optical fiber. Each wavelength carries a unique data channel, allowing you to aggregate and transport data from various services simultaneously.

 

2. Increased Bandwidth: By leveraging CWDM technology, you can significantly increase your network's bandwidth capacity. This allows you to meet the growing demands of your customers for high-speed internet, digital TV, and other data-intensive services without the need to lay additional optical fibers.

 

3. Cost-Effectiveness: CWDM is a cost-effective solution compared to other optical networking technologies, such as Dense Wavelength Division Multiplexing (DWDM). CWDM uses wider wavelength spacing, reducing the complexity and cost of the optical components required.

 

4. Compatibility: CWDM is compatible with various communication protocols and data rates, making it suitable for various applications. It with Ethernet, SONET/SDH, or Fibre Channel, CWDM can efficiently handle diverse data types.

 

5. Long-Haul and Metro Applications: CWDM is well-suited for both long-haul and metro network applications. It transmits data over long distances between cities or within a metropolitan area, CWDM offers reliable and high-performance data transmission.

 

6. Optical Amplification: For longer-distance transmissions, CWDM systems can be combined with optical amplifiers to extend the reach of your network while maintaining signal integrity and quality.
