Quality control (QC) is a process through which a business seeks to ensure that product quality is maintained or improved. Quality control involves testing of units and determining if they are within the specifications for the final product.
CWDM stands for Course Wavelength-Division Multiplexing.
The CWDM method multiplexes optical signals together on one single fiber. To achieve this it uses different colors (wavelengths) which are combined in a MUX. The device where the optical signals are multiplexed and de-multiplexed is called a MUX or a fiber optical multiplexer or a CWDM multiplexer. In most cases these MUXES are passive so no electricity is needed, hence the meantime between failures is about 500 years.
All optical transmission is done by dual fibers where one fiber is transporting data from east to west and the other west to east. This dual function is possible because one MUX has both a multiplexer and a de-multiplexer. There are two standards for multiplexing: CWDM and DWDM. The main difference is the wavelength steps between the channels: for CWDM this is 20nm (course) and for DWDM this is typically 0.8nm (dense). CWDM has 18 wavelengths from 1610 to 1270 with steps of 20nm. *This particular model has four wavelengths- 1271nm, 1291nm, 1471nm, 1491nm.
This particular model operates at temperatures of –40° to 85°C (–40° to 185°F). It is black in color with green and white covering connector covers on the faceplate. It measures 1x5x7.
