CWDM can effectively save up the resource of fiber and cost of network technology, which deal with the shortage of optical fiber and transparent transmission of business. With low-cost, low power consumption and small compact, it is widely used in metro aggregation and access layer to do transmission on a short time.

FWDM-T1550R1310/1490 and PWDM-T1550r1310/1490 are used in optical model package, which can make 1550, 1490/1310, 2 wavelength optical signal, both Wavelength Division Multiplexer, make single fiber transmission capacity, also make the single fiber transmission in two direction, widely used in fiber-optic network upgrade. Expansion or introduction of a comprehensive new business (radio, television, telecommunications, internet triple play PON+ EOC) and so on.
