The shape design of the Citroen Metropolis concept car is very romantic, multi-curve design, stylish and avant-garde, worthy of the French brand. The Citroen Metropolis concept car exceeds the BMW 7 Series in size, an absolutely luxurious model. The lines on the side body are smooth and slender, and the flat top is the guarantee of the spacious space in the back row.
The large front face not only has a powerful and hard air, but also a full and round head gives a stylish sports experience. The whole body of the Citroen Metropolis concept car uses a large number of chrome alloys as decoration, bright silver, and visual effects. We are also obvious to all.
The taillights still use LED lighting, and the layout of the internal light group is more layered. The vortex wheel design, I believe that few people can withstand the visual impact of it.
CWDM - Coarse Wavelength Division Multiplex
CCWDM is Compact CWDM (Compact Coarse Wavelength Division Multiplexing), a wavelength division multiplexing technology based on TFF (Thin Film Filter). It works in the same way as CWDM modules, except that CCWDM uses free space technology. , compared with the common CWDM optical fiber cascading method , the CCWDM package size is greatly reduced compared with CWDM modules, and the insertion loss is lower and the consistency is better; it can replace CWDM Products are used in telecommunications, enterprise networks, PON networks, cable television and other fields. The lower insertion loss enables the CCWDM module to have lower signal attenuation during use, thereby reducing the power requirements of the signal transmitter.
For the CWDM module, limited by the minimum bending radius of the optical fiber line, the size of the packaging box cannot be made too small, resulting in most of the space in the box being idle. The adjacent channels of CCWDM use parallel beams to cascade in free space instead of optical fibers. Without the optical fiber used for cascading, the size of the CCWDM packaging box can be greatly reduced. For example, the size of the common standard 4CH CWDM is 80×60×12 mm, and the size of the CCWDM module of Yiyuantong is 50×27×7.7mm, which is only 1/4 of the standard CWDM package size. Can be widely used in high-density environments.
