Today's audio, video and data networks are more complex requiring more bandwidth and faster data transfer rates for long distances. These demands mean more performance requirements for fiber optics. The existing optic network can be cost-effectively expanded by dividing fibers for more than one user. This technology is called Coarse Wavelength Division Multiplexing, in other words CWDM.

Benefits:

• Passive component: No electricity needed
• More economical per channel than DWDM (Dense Wavelength Division Multiplexing)
• Scalability enables better utilization for fibers with low cost growth
• Easy to install and use
