3 port 1310/1490/1550nm Micro-Optical WDM

MWDM reuses the first 6 waves of CWDM, compresses the 20nm wavelength interval of CWDM to 7nm, and uses TEC (Thermal Electronic Cooler) temperature control technology to realize 1 wave expansion into 2 waves. In this way, the capacity can be increased while further saving fiber.
