CWDM is also called coarse wavelength division multiplexer (sparse wavelength division multiplexer), with large frequency intervals. The common wavelength of CWDM is 1270-1610nm, and the channel spacing is 20nm.
Commonly used package form；
Wavelength converter (OEO): It mainly reshapes and regenerates the optical signal to ensure the integrity of the optical signal and transmit it over longer distances.
It is mainly divided into 100M, Gigabit, 10G OEO, OEO board and OTU board card based on the rate.
Solve the problem: the distance between the two sites is too long, and the optical cable resources are compact.
Sharetop program description:
1. Site A uses OEO to convert customer multi-mode signals into single-mode long-distance signals, and enters wavelength division multiplexing;
2. The relay station uses OEO to relay, amplify and regenerate the signal, and realize single-fiber and dual-fiber conversion and transmission to station B;
3. Station B adopts OEO to amplify and regenerate signals, and realize single-dual fiber conversion, single-multi-mode conversion;
Advantages of sharetop solution:
1. Use OEO to convert multi-mode to single-mode to realize long-distance transmission
2. OEO adopts 3R design, which can regenerate and amplify the signal, shape the waveform, and the clock is in timing to ensure high-quality signal transmission
3. Use OEO for single-to-dual fiber conversion, and use wavelength division multiplexing equipment to save fiber optic cable resources and help customers save costs
