CWDM / DWDM
Current infrastructure challenges?
• Would you like to run more services over your existing infrastructure, but do not have enough fibers?
• Would you like to mix different services running over the same fiber?
• Would you like to use more efficiently the fiber you lease and save CAPEX?
• Would you like to make more money from fiber renting business?
If answered YES for at least one question, Polixel will help you to achieve!
Wavelength Division Multiplexing (WDM) is a method of transmitting data from different sources over the same fiber optic link at the same time whereby each data channel is carried on its own unique wavelength. The result is a link with an aggregate bandwidth that increases with the number of wavelengths employed. In this way WDM technology can maximize the use of the fiber optic infrastructure that is available; what would normally require two or more fiber links instead requires only one.
- Coarse Wave Division Multiplexing (CWDM) combines up to 16 wavelengths onto a single fiber. CWDM technology uses an ITU standard 20nm spacing between the wavelengths, from 1310nm to 1610nm. With CWDM technology, since the wavelengths are relatively far apart (compared to DWDM), the transponders are generally not very expensive.

- Dense WDM (DWDM) combines up to 64 wavelengths onto a single fiber. DWDM technology uses an ITU standard 100GHz or 200GHz spacing between the wavelengths, arranged in several bands at ~1500-1600 nm. With DWDM technology, the wavelengths are close together (compared to CWDM), meaning that transponders are generally more complex and expensive than CWDM. However, with dense WDM (DWDM), the advantage is a much higher density of wavelengths, and also longer distances, especially with low dispersion solution.
