Reality VR (Virtual) technology is a comprehensive application of a variety of techniques to create a realistic artificial simulation environment, simulation of human in the natural environment of a variety of cognitive behavior of the advanced human-computer interaction technology.

Optical fiber cleaning method1: Fiber joint cleaning can not use cotton with alcohol is why? The cleaning requirements of optical fiber connectors are much higher than those of the camera lens. Cotton or lens paper fiber is thicker, easy to cause the wear of optical fiber connector. Foreign already

The research of optical fiber connector causes optical fiber connector polishing as one of the most important optical passive devices in fiber system.

WDM (Wavelength Division Multiplexing) technology refers to the use of multiple laser beams in the same fiber simultaneously transmit multiple wavelengths of light technology.

Fiber optic connectors, commonly known as live connectors, are proposed to be defined as "passive components that are stable but not permanently connected to two or more optical fibers" (CCITT, group VI, March 1992, passed in Geneva, ITU).

In recent years, the rapid development of the Internet has led to the emergence of new business such as e-commerce, social media and Internet financial services.

FTTB, FTTC, FTTD, FTTH, FTTK, FTTN, and FTTP all redirect here. For airports with those ICAO codes, see List of airports in Chad.

Direct fiberThe simplest optical distribution network architecture is direct fiber: each fiber leaving the central office goes to exactly one customer.

The simplest form of telecommunications takes place between two stations.

A new battle is breaking out between Verizon and the state of New Jersey, over promises Verizon made nearly a decade ago.
