Description


                                                                  18ch CCWDM MODULE

 

         

        Vsunlight’ s Compact CWDM is the low insertion loss version of CWDM Mux. Compare with traditional CWDM technology,CCWDM technology adopts free-space optics platform which can significanty improve optical performance.  of which the wavelength is 1271,1291......1611 nm in the CWDM ITU grid (20 nm spacing), the number of common channels is 4CH, 8CH, 16ch ,18CH. 

        The 18CH Mux Demux is a cost-effective, flexible, and suitable for short-distance transmission passive CWDM device based on Free Space technology. This unit can be used as either a multiplexer or de-multiplexer (mux/demux). In accordance with the ITU-T G.694.2, it maximizes the capacity of the C-band range.

Technology

The CCWDM Mux adopts free-space technology,which uses light propagating in free space to wirelessly  transmit data.Inside the device,adjacent signal channels are cascaded by parallel beam instead of the fiber.

 Extreme Low Insertion Loss

The insertion loss of CCWDM Mux is about half of the conventional CWDM Mux.This reduces the overall of the whole link,and leaves more choices for the design of the solution.
