The main difference between CWDM and CCWDM is that the CWDM system uses a low-cost, non-cooling distributed feedback (DFB) laser, while the collimator and filter of CCWDM are welded on a common substrate. The cascade structure of the two is different.
A three-port filter used for a specific wavelength of CWDM. Its wavelength channel is composed of two lenses and a TFF matched to the specific wavelength. The reflection port of each filter is connected to the common port of the next filter, and the filters are connected by Optical Fiber connectors, which is a CWDM multiplexer.
The compact CCWDM coarse wavelength division multiplexer is in the compact free space CWDM device, the multi-wavelength optical signal enters from the input fiber. The principle is to use the input lens to focus the optical signals with wavelengths λ1, λ2...λn on the input fiber to the first filter; the optical signal with wavelength λ1 passes through the first filter and is coupled to the first output lens In the first output fiber, the optical signal with a wavelength of λ1 is separated; the remaining optical signals are reflected by the first glass slide to the next slide for optical signal separation; and so on, until all the signals are separated. The coupling between the wavelength channels is realized in the form of straight rays that follow the "Zigzag" route.
Different from Dense Wdm Splitter and Coarse Wdm Splitter, compact coarse Wdm Splitter is smaller and highly reliable when compared to other Wdm Device. CCWDM is also commonly used along with Network Device like Gepon Ont, Gepon Onu, etc.
