Mini Coarse Wavelength Division Multiplexer 8 Channel CWDM 1/8
The average size of CWDM is larger, it is not convenient to install in small devices.Mini CWDM has the advantages of small volume, small space requirement,the parameters can still meet the requirements of ordinary CWDM.
Due to the small size of the mini CWDM, the manufacturing process must be carried out using special materials for coupling packaging.Therefore, the cost of mini CWDM is higher than that of ordinary CWDM.
