Advantages of FTTH Networks and Wiring Solutions

FTTH (Fiber To The Home), as the name suggests, is an optical fiber directly to the home. Specifically, FTTH refers to the installation of optical network units (ONUs) at home users or enterprise users, and is the optical access network application type closest to users in the optical access series except FTTD (fiber to the desktop). The significant technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the transparency of the network to data formats, rates, wavelengths and protocols, relaxes the requirements for environmental conditions and power supply, and simplifies maintenance and installation.

The advantages of FTTH are mainly 5 points: first, it is a passive network, from the central office to the user, it can basically be passive in the middle; second, its bandwidth is relatively wide, and the long distance is just in line with the operator Third, because it is a business carried on optical fibers, there is no problem; fourth, because of its wider bandwidth, the supported protocols are more flexible; fifth, with the development of technology, Including point-to-point, 1.25G and FTTH methods have developed relatively complete functions.

The advantages of independent ip fttx optical cable routing solution, fttx optical cable routing selects optical cables of different structures according to 3 different areas, and uses feeder cables in the area of ​​​​the computer room. Because in addition to the overall wiring scheme of fttx, the number of optical fiber cores when the optical splitter is placed out of the equipment room is the same. Tube layer stranded cable.

The benefits of independent ip The system is mainly composed of olt and onu and splitter, olt provides 4 upstream interfaces to the ip network, and 4 epon downstream ports, each port supports 32 optical fibers on a single fiber Split, if this single olt device can accommodate 128 onu users, the transmission distance can reach 20km. Its height is only 1u, and it is convenient to install and disassemble.

The onu device onu is the user-side device of the g/epon system, and is used to terminate the business transmitted from the olt through pon. In cooperation with olt, onu can provide various broadband services to connected users. Such as internet, voip, hdtv, videoconference, etc. As a user-side device used by fttx, onu is a high-bandwidth and cost-effective end device necessary for the transition from the "copper cable era" to the "optical fiber era".

Indoor wiring optical cable is used to transmit optical signals from one place to another in a building. It is required that the optical cable has a simple structure, is soft and easy to lay, and has a small bending radius for easy laying in corners. Function, the indoor wiring optical cable without the following structure does not have the above characteristics.

The outdoor optical cable transfer box is mainly used for the connection, distribution and placement of the communication optical cable to each optical distribution point after it leaves the computer room, and manages the optical fiber and cable management equipment smartly. Mainly complete the introduction and fixation of the optical cable outside the pon access network, the fusion and wiring of the optical fiber, the installation and disassembly of the optical splitter, and the splitting and deletion of the optical line. Products include splitter and splitter-free fiber optic cable junction boxes. According to the different quantity of materials, the products currently supplied are divided into two categories: smc box optical cable transfer box, stainless steel box optical cable transfer box.

The planar optical waveguide technology uses semiconductor technology to manufacture optical waveguide splitting devices. The function of splitting is completed on the chip, and it is possible to complete more than 1 × 32 splitting on one chip, and then separate coupling seals at both ends of the chip. Disassemble the input and output multi-channel fiber arrays.
