The structure of the self-supporting pre-terminated drop cable is based on the Butterfly cable, and a metal suspension unit is added. With the continuous extension of the optical fiber like the user end, in order to meet the different uses and requirements, and expand the use range of the butterfly-introducing cable, on the basis of the Pre-terminated Drop Cable, a derivative product of the butterfly-introducing has emerged, the most typical one being The Self-supporting Pre-terminated Drop Cable is introduced into the optical cable.READ MORE
The optical fiber unit, Pre-terminated Drop Cable, is positioned in the center.Two parallel Fiber Reinforced Plastics (FRP) are placed at the two sides.Then,the cable is completed with a black or color LSZH sheath. It is also called leather cable. It is a new type of user access optical cable. According to the application environment and laying conditions, the cable structure and various technical parameters are reasonably designed. The characteristics of indoor soft cable and self-supporting optical cable are collected. Special equipment is used in conjunction with imported precision mold production. It is the best candidate for FTTX network solution, and it is also suitable for users of other fiber-optic FTTO and FTTB networks. Because the cross-section is like a butterfly, it is called a butterfly cable. Both sides are reinforcing members in the leather line and optical fibers in the middle.
OC240-Cross Connecting Cabinet is use for outdoor cable access network, backbone cable and indoor cable arrangement. it with high-capacity, high-density fiber distribution tray, suitable for the composition, splice and distribution of fibers in optical access network to achieve the fiber optic lines connection, distribution and scheduling.The oc240-cross connecting cabinet is a kind of outdoor cabinet. It refers to a cabinet made of metal or non-metal materials directly under the influence of natural weather. It does not allow unauthorised operators to enter the operating cabinet, providing wireless communication stations or wired network station workstations.
OC144-Cross Connecting Cabinet is an outdoor optical equipment that is especially designed for outdoor optical nodes in access net work. The cabinet has the functions of optical fiber cable splice, distribution, splitter holding, storage and dispatch. It has great performance of resisting the open-air environment and can resist severe climatic changes and serious working environment. The protection grade reaches IP65.
"GY" means Outdoor optical cable for communication,"T" means Filled structure,"A" means Aluminum belt--polyethylene bonding layer. The GYTA cable is a loose tube made of a high-modulus material, which is filled with a 250 μm fiber. And the loose tube is filled with a waterproof compound. The center of the core is a metal reinforced core. For some cores, a layer of polyethylene (PE) is required to be extruded outside the metal reinforced core.
GPON-4081 Optical modem is the abbreviation of modulator and demodulator. Chinese called modem (known as the data machine in Hong Kong and Taiwan). According to the homophonic sound of Modem, it is called "cat" relatives. It is a device that converts a digital signal into an analog signal by modulation at the transmitting end and converts the analog signal into a digital signal by demodulating at the receiving end. The so-called modulation is to convert the digital signal into an analog signal transmitted on the telephone line; demodulation, that is, converting the analog signal into a digital signal. The so-called modem. The English language of the modem is MODEM, which is used as a "translator" for analog signals and digital signals.
SFP DAC Optical module, as one kind of optical transceiver assembly, a direct attach cable (DAC) is used to connect one mobility access switch with another when forming a stack, which can be either passive or active. Since the passive DAC contains no active components, it provides a direct electrical connection between corresponding cable ends. This process can also be done by an active DAC that is considered active because there are optics and/or electronics embedded within the connectors. Thus it helps to improve signal quality and provide a longer cable distance.
Optical Fiber Connector is a reusable passive device used to connect two fibers or cables to form a continuous optical path. It has been widely used in optical fiber transmission lines and fiber distribution frames. And optical fiber test instruments and meters are the most used optical passive components. According to different classification methods, optical fiber connectors can be divided into different types. According to different transmission media, they can be divided into single-mode fiber connectors and multi-mode fiber connectors. According to different structures, they can be divided into FC, SC, ST, and D4. , DIN, Biconic, MU, LC, MT and other types; according to the pin end face of the connector can be divided into FC, PC (UPC) and APC; according to the number of fiber cores, there are single core, multi-core.
