    ZyXEL OLT-2300 Series Support Notes What is the rationale of wavelength-division multiplexing (WDM)? In fiber optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes/de-multiplexes multiple optical carrier signals to/from single optical fiber. This allows for a multiplication in capacity in single fiber, in addition to making it possible to perform bidirectional communications over single fiber.

  • Page 30: Why Single Mode Is Necessary For Pon Network

    ZyXEL OLT-2300 Series Support Notes Why single mode is necessary for PON network? In fiber optic communications, a single-mode optical fiber is an optical fiber designed to carry only a single ray of light (mode). This ray of light often consists of a variety of different wavelengths.

    ZyXEL OLT-2300 Series Support Notes x L total fiber length. To reduce fiber deployment, it is possible to deploy a remote switch or concentrator close to the neighborhood. This will reduce the fiber consumption to L km, but will actually increase the number of transceivers to 2N+2, as there is one more link added to the network (Fig.

  • Page 32: What Is Optical Splitter

    ZyXEL OLT-2300 Series Support Notes What is Optical splitter? An optical splitter is a passive device that splits the optical power carried by a single input fiber into multiple output fibers. Higher split ratio means more ONUs can access the fiber. The input optical power is normally split evenly between the output fibers.

    ZyXEL OLT-2300 Series Support Notes uniformity specification in dB. Typical uniformity specifications for a 1x32 splitter are in the range from 2 to 3 dB, depending on the manufacturer. What is the meaning of fixed attenuation and optical fiber attenuation? Attenuation in the fiber plant arises from fixed components such as splitters and patch panel (distribution frame) connectors, as well as from fiber attenuation.
