FIBERWDM is the original manufacturer of DWDM equipment with over 10 years of experience and a mature team, providing free DWDM transmission solutions to customers.

DWDM network is an optical transmission technology used to simultaneously transmit multiple optical signals of different wavelengths in optical fibers. It achieves high-capacity optical communication by associating each signal with a unique wavelength and merging them into the same optical fiber. DWDM is widely used in industries such as broadcasting, IDC, finance, cloud computing, and massive data where fiber optic resources are scarce.

The working process of DWDM is as follows:

Transmitting end: The laser modulates laser photons of different wavelengths into optical signals with signals through a modulator, and then combines multiple optical signals of different wavelengths into one signal stream through a splitter, which is transmitted to the receiving end through an optical fiber.

Fiber optic transmission link: Multiple optical signals of different wavelengths are transmitted to the receiving end in the same fiber optic cable, and the signals are distinguished by different wavelengths.

Receiver: Separate and demodulate optical signals of multiple wavelengths through a demultiplexer, and transmit the signals of each channel to a signal processor for further processing.

The application is as follows:

20 Channels DWDM MUX/DEMUX, insertion loss is less than 3.5dB( line loss<7dB) , and totally passive DWDM device,support 20 channels difference business in one optical fiber for point-to-point transmission.
