  2. Remote Skylights - Wikipedia

    en.wikipedia.org/wiki/Remote_Skylights

    Remote Skylights are optical systems capable of providing natural light to unlit locations. An arrangement of parabolic reflectors and optical fiber cables, transport natural sunlight to areas that would otherwise be dark or be lit artificially. Remote skylights are composed chiefly of a solar collection dish, a "heliotube" and a distribution ...

    A keystone module for a CAT5 network cable A 3-port keystone wall plate. A keystone module is a standardized snap-in package for mounting a variety of low-voltage electrical jacks or optical connectors into a keystone wall plate, face plate, surface-mount box, or a patch panel.

  4. Fiber-optic adapter - Wikipedia

    en.wikipedia.org/wiki/Fiber-optic_adapter

    A fiber optic coupler is a device used in optical fiber systems with one or more input fibers and one or several output fibers. Light entering an input fiber can appear at one or more outputs and its power distribution potentially depending on the wavelength and polarization. Such couplers can be fabricated in different ways, for example by ...

    en.wikipedia.org/wiki/Optical_fiber

    These fiber optic coating layers are applied during the fiber draw, at speeds approaching 100 kilometers per hour (60 mph). Fiber optic coatings are applied using one of two methods: wet-on-dry and wet-on-wet. In wet-on-dry, the fiber passes through a primary coating application, which is then UV cured, then through the secondary coating ...

    RRHs are generally connected to the baseband unit or base station which can be an x86 server [2] on the ground near a cell tower, via a fiber optic cable using Common Public Radio Interface protocols. [3] CableFree 4G/5G Remote Radio Head (RRH) with 2x2 MIMO, 2x20W RF power and CPRI fibre interface

  7. Optical isolator - Wikipedia

    en.wikipedia.org/wiki/Optical_isolator

    Optical isolators are different from 1/4 wave plate based isolators [dubious – discuss] [clarification needed] because the Faraday rotator provides non-reciprocal rotation while maintaining linear polarization. That is, the polarization rotation due to the Faraday rotator is always in the same relative direction.

  9. Optical amplifier - Wikipedia

    en.wikipedia.org/wiki/Optical_amplifier

    The erbium-doped fiber amplifier (EDFA) is the most deployed fiber amplifier as its amplification window coincides with the third transmission window of silica-based optical fiber. The core of a silica fiber is doped with trivalent erbium ions (Er 3+ ) and can be efficiently pumped with a laser at or near wavelengths of 980 nm and 1480 nm, and ...
