The Difference between the Indoor And Outdoor Fiber Optic Cable

According to the different environment, fiber optic cable is generally divided into indoor cable and outdoor cable, indoor cable is formed by a certain process of cable, mainly by the optical fiber (such as hair glass) and plastic protective casing and plastic skin composition. Outdoor cable is a communication line to achieve optical signal transmission. By a certain number of fiber in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer layer. Mainly by the optical fiber and plastic protective casing and plastic skin composition. The tensile strength of the indoor fiber is small, the protective layer crosses, but relatively lightweight, economical, mainly used in horizontal cabling subsystems and vertical trunk subsystems. Outdoor cable tensile strength is greater, the protective layer is more heavy, and usually armored (that is, metal skin wrapped). Outdoor cable is mainly used between buildings, as well as the interconnection betw...

Differences Between FBT and PLC splitters

图片
In FTTx and PON architectures, fiber optic splitter is an important component to share the optic network with multiple users. The basic principle of fiber optic splitter is to split one optic light beam into several parts at a certain ratio. According to different manufacture technologies, fiber optic splitters can be divided into PLC splitter and FBT splitter. You may wonder the differences of the two splitter types when making a choice between them. This article aims at helping you to understand their distinctions and make better decisions. Basics of PLC & FBT Splitters What Is  PLC Splitter ? PLC refers to planar lightwave circuit. As a micro-optical device, PLC splitter uses an optical chip to split the input signal into various outputs. At the edge of the chip, there is a light circuit in ribbon form mounted on a carrier and fibers. PLC splitter typically adopts silica glass as the material of lightwave circuit and accepts different types of polished finishes. The s...

Differences between FTTH, FTTC, and FTTN

图片
FTTH, FTTC and FTTN are fiber optic legs. Made of strands of glass, fiber optic Internet provides faster, smoother service with more room for signal traffic compared to traditional copper cable wires. FTTH (Fiber to the Home), FTTC (Fiber to the Curb) and FTTN (Fiber to the Node) refer to the wiring path and configuration the signals travel. The closer the fiber optic legs reach to the final destination, the better the connection. How do FTTH, FTTC and FTTN differ? FTTH (Fiber to the Home) moves between the property line switch box and the residents’ junction boxes. Because the connection goes directly to individual residences, FTTH offers a higher bandwidth. It’s expensive to install in some areas. Some carriers install fiber optics for this leg as a selling feature in new developments. But, a FTTH home has a disadvantage if a carrier needs to install a separate power line. Power and Internet signals don’t move together in fiber optics. FTTC (Fiber to the Curb) doe...
