Do You Know These Advantages of CWDM?

With the development of data communication and telecommunication technology, the intention of MAN(Metropolitan Area Network)is no longer relative to the wide area network. Due to the high bandwidth and data transmission transparency of DWDM(Dense Wavelength Division Multiplexing) tech, people naturally hope to introduce DWDM as the platform of MAN. However, in the MAN, an optical amplifier is not needed on…
