The ZXMP M600 is a coarse wavelength division multiplexing (CWDM) equipment developed by ZTE Corporation. It is applicable to the convergence layer and access layer of large metro area network (MAN), and all layers of medium/small MAN. ZXMP M600 supports transparent transmission of various services at multiple rates. With its low cost, large capacity, transparent transmission and expansibility, ZXMP M600 is a cost-efficient solution to fiber scarcity in the access and convergence layers of MAN.
