Dense wavelength division multiplexer(DWDM) is based on the membrane filter technique and proprietary non-flux metal bonding micro-optics packaging design, within ITU wavelengths to achieve uplink and downlink. It provides ITU channel center wavelength, low insertion loss, high channel isolation, low power consumption, wide passband characteristics, no glue loop, excellent thermal stability and reliability and so on. In a telecommunications network system, it can be used for uplink or downlink optical signal.Optico’s DWDM product delivers dramatic cost savings to network equipment manufacturers, enabling them to develop metro access systems that are lower in cost, easier to provision and simpler to operate.

DWDM Principle:
In the actual operation, in order to make reasonable use of the broadband resources generated by a single-mode fiber in a low-loss region (such as the 1.55 pm low-loss region), it is necessary to divide the low-loss region of the fiber into multiples according to different frequencies and wavelengths. Optical channel, and it is necessary to establish a carrier wave in each optical channel, that is, what we call light wave, and at the same time, use a demultiplexer to combine signals of different predetermined wavelengths at the transmitting end, and collectively transmit these combined signals into one optical fiber for performing. Signal transmission. When transmitting to the receiving end, these are combined with different wavelengths using an optical demultiplexer. The decomposition of the signals of different light waves into the initial state realizes the function of transmitting a plurality of different signals in one optical fiber.
