2. Fiber-optic patch cord - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_patch_cord

   The transceiver modules launch only single-mode 1300 nm signals but the existing network is built with multimode cables. With a single-mode laser aimed into the center of a multimode fiber, the signal arriving at the far end, having followed various paths in the fiber, is spread out in time, making fast transitions between light and dark ...

3. Single-mode optical fiber - Wikipedia

   en.wikipedia.org/wiki/Single-mode_optical_fiber

   In fiber-optic communication, a single-mode optical fiber (SMF), also known as fundamental- or mono-mode, [1] is an optical fiber designed to carry only a single mode of light - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell's equations and the boundary conditions.

4. XFP transceiver - Wikipedia

   en.wikipedia.org/wiki/XFP_transceiver

   XFP are available with a variety of transmitter and receiver types, allowing users to select the appropriate transceiver for each link to provide the required optical reach over the available optical fiber type (e.g. multi-mode fiber or single-mode fiber). XFP modules are commonly available in several different categories: [citation needed]

   The most common type of single-mode fiber has a core diameter of 8–10 micrometers and is designed for use in the near infrared. Multi-mode fiber, by comparison, is manufactured with core diameters as small as 50 micrometers and as large as hundreds of micrometers.
