DESCRIPTION
This product is to transmit 2Ch Video, 1Ch Audio, 1Ch Datasignals through 1core, combining the system according to the need.
It is generally called MUX equipment. There are a lot of types by way of combination. It can be manufactured according to the site and
customer requests except for the described products. It is the method using optical characteristics, capable of no-relay long-distance
transmission, and getting no influence from electric field and magnetic field. Having input and output display LED,
it shows the data communication state visually. 7Segment LED window on the front panel of the equipment shows image signal input and
output voltage and optical cable cut. This Equipment is used C.W.D.M(Coarse Wavelength Division Multiplex).
