1 IntroductionCommunication plastic optical fiber (hereinafter referred to as plastic optical fiber) development of the beginning of almost the same as the glass optical fiber, both from the 1960s. But from the 197x era, the development of glass optical fiber is like hanging, while the plastic optic

Increasing the number of optical fiber cores is the most efficient way to increase the transmission capacity of fiber optic cable lines. However, it will also bring a series of problems such as fiber diameter is too thick, fiber can not be identified, repair difficulties and so on. This article will

This is a technology that collects sunlight through outdoor lenses and then uses optical fibres to channel it into the room for lighting. It mainly consists of an outdoor light collection system, a light guide system and an indoor light projection system. Outdoor sunlight is collected by a light col

1. Increase the switchThe longest transmission distance of category 5 and category 6 network cable is 100 meters, if you want to increase the transmission distance, you can install relay equipment such as switches between the two twisted-pair cables, theoretically up to 4 switches can be installed.

Fiber optic cable lines and broadband access projects usually involve fiber optic cable single disk testing and fiber optic cable line testing, fiber optic cable line testing includes: relay section testing, user cable testing and so on. These test entries, some only need to use the test instrument

1Q: What do the various diameter parameters in fiber optic patch cords represent?A: These parameters are related to the fiber structure.From the cross-section, the internal structure of the fiber as shown in the figure above, the corresponding parameters are interpreted as follows:
