Optical Networking Solutions
There's two types of WDM Optical network: CWDM (Coarse Wavelength Division
Multiplexing) and DWDM (Dense Wavelength Division Multiplexing). CWDM
systems typically provide 18 wavelengths, separated by 20 nm, from 1470nm
to 1610nm according to ITU-T standard G.694.2. However, for different
applications, there are different ITU-T standard to define the specific wave
range and channels. Compared to CWDM, DWDM is defined in terms of
frequencies. Some DWDM network systems provide up to 96 wavelengths,
typically without any more than 0.4 nm spacing, roughly over the C-band range
Rollball also provide Qsfp active optical cables, qsfp direct attach cables, fiber
patch cord, fiber adapters, fiber attenuators and other fiber optical solutions.
