A WDM optical network is a wavelength density network on fiber optics. The WDM equipment makes it possible to connect several different information channels/signals inn to one fiber, Witch makes it possible to transport enormous amounts of information on tiny little optical fiber. It`s mostly used on long length between connection points, and not directly to buildings and homes.
So theoretically if you want to send me 100GB of information, and you want to send it to me in less then 5 seconds, between us we have one fiber and each our WDM equipment. If our internet provider offers this to be a posebility, they would have to give us 10 channels of 2GB each.
100GB/5s=20GBps
Ideally this would work, if you don`t count the loss in the fiber or units.

Basic interview knowledge of OLT and ONU system Basic interview knowledge of outside plan system Basic interview opt?
OLT (Optical Line Terminal) is a device in a passive optical network that serves as the service provider's endpoint, connecting to and controlling multiple Optical Network Units (ONUs) at subscriber locations. ONU is a customer premises equipment that connects to the OLT in a PON system. An Outside Plant (OSP) system refers to the network infrastructure installed outside of buildings, including cables, ducts, poles, and cabinets, that transmits telecommunications signals. OSP designs facilitate the deployment of cables and equipment for communication networks. "Basic interview opt" may refer to questions related to optical network technology, such as understanding different types of optical fibers, WDM technology, network architectures, or troubleshooting common optical network issues during an interview for a position in the telecommunications or networking industry.
What is Optical line terminal?
An optical line termination (OLT), is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: - To perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network. - To coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).

What are MUX and DEMUX in WDM?
WDM (Wavelength Division Multiplexing) is to combine a series of optical carrier signals at different wavelengths carrying various information at the transmitter through the Multiplexer and couple them to the same optical fiber for transmission. At the receiver end, the optical signals are separated from each other by a Demultiplexer. The simultaneous transmission of two or many optical signals of different wavelengths in the same fiber is called Wavelength Division Multiplexing (WDM). WDM technology can double the transmission capacity of a single light, which can easily expand the capacity of existing optical networks. Depending on the direction of the transmitted signal, WDM can be used for multiplexing or demultiplexing. MUX The main function of MUX is to combine multiple signal wavelengths into one optical fiber for transmission. At the transmitter end, N optical transmitters operate at N different wavelengths, which are separated by appropriate intervals. These N light waves are respectively modulated by the signal as carriers and carry the signal. A wave synthesizer combines these different wavelengths of optical carrier signals and couples them into a single-mode fiber. Because the optical carrier signals of different wavelengths can be regarded as independent of each other (without considering the non-linearity of the fiber), the multiplexing transmission of multiple optical signals can be realized in one fiber. Through multiplexing, communication operators can avoid maintaining multiple lines and effectively save operating costs. DEMUX The main function of DEMUX is to separate multiple wavelength signals transmitted in one fiber. At the receiving end, the optical carrier signals of different wavelengths are separated by a demultiplexer, which is further processed by the optical receiver to recover the original signal. A demultiplexer (Demux) is a device that performs reverse processing on a multiplexer. Performance Parameters of MUX/DEMUX 1. Operating Wavelength Multiplexer/demultiplexer operating waveband. For example, 1550 wavelength has three bands: S band (short wavelength band 1460~1528nm), C band (conventional band 1530~1565nm), L band (long wavelength band 1565~1625nm). 2. Number of channels & channel spacing Channel number refers to the number of channels that a multiplexer/demultiplexer can combine or separate. This number can range from 4 to 160 to enhance the design by adding more channels. Common channels are 4, 8, 16, 32, 40, 48, etc. Channel spacing is the difference between the nominal carrier frequencies of two adjacent channels and is used to prevent inter-channel interference. According to ITU-T G.692, the channel intervals less than 200GHz(1.6nm) include 100GHz (0.8nm), 50GHz (0.4nm) and 25GHz. Currently, 100GHz and 50GHz channel intervals are preferred. 3. Insertion Loss Insertion loss is the attenuation caused by the insertion of WDM in optical transmission system. The attenuation effect of WDM on optical signal directly affects the transmission distance of the system. Generally, the lower the insertion loss, the less signal attenuation. 4. Isolation Isolation refers to the isolation degree between signals of each channel. High isolation values can effectively prevent the distortion of transmitted signals caused by crosstalk between signals. 5. PDL (Polarization Dependent Loss) PDL refers to the distance between the maximum and minimum loss caused by different polarization states at fixed temperature, wavelength and the same band, namely, the maximum deviation of insertion Loss in all input polarization states.
