<p>With the rapid development of the information age, people's demand for communication services is no longer simple voice or one-way video, but tends to be faster, richer, and interactive broadband media services, although traditional telecommunications networks, broadcasting Television networks and computer Internet have their own characteristics and advantages, but none of them can meet the needs of users for broadband access and integrated access. Therefore, the integration of the three networks becomes inevitable. It can not only meet the needs of the times and users, but also It can also effectively save the waste of resources, so do you know what the triple play is? What is the triplex <a href="https://www.tel-bridge.com/wall-mount-odf" rel="noopener noreferrer" target="_blank">fiber optic distribution frame</a>? How should it be installed and used?</p><p><br></p><p>What is one and three networks in one?</p><p>Three networks refers to the three major networks of telecommunications networks, radio and television networks and the Internet. The three networks in one is to integrate the existing and independent traditional telecommunications network, computer broadband network and limited television network to achieve mutual penetration and unification, and finally a variety of services through an independent network The physical link is presented to the information consumer. Therefore, the three-in-one network system has the following characteristics:</p><p><br></p><p>(1) Users only need a physical network connection to enjoy the resources of other networks or communicate with users on other networks.</p><p><br></p><p>(2) The network is interoperable at the physical layer, which means that the signals of one network can be directly transferred or organized or transformed to another network, and when it is transmitted to the user terminal through another network, the information is not changed. Content, that is to say, the network must be transparent to each other.</p><p><br></p><p>(3) The services between the networks penetrate and cross each other at the application layer, but they can be independent of each other without hindering each other, and they can independently develop their own new services on the respective networks as before.</p><p><br></p><p>(4) The protocols between the networks are compatible or can be converted. This is because each network has its own protocol, so when information is transferred from one network to another, it should meet the protocol requirements of the transferred network.</p><p><br></p><p>2. Introduction and function of three-in-one fiber distribution frame</p><p>It can be seen from the above that the importance of triple play is also an inevitable development trend in the future. When triple play is realized, we will definitely use triple play optical distribution frame. What is triple play optical distribution frame? ? What does it do? The three-in-one fiber optic distribution frame is a wiring device for terminating, protecting, connecting and managing optical cables/optical fibers in the optical fiber communication network. It is an important supporting facility for the optical access network and is mainly used for optical fiber fusion splicing of optical cable terminals. Installation of optical fiber connectors, adjustment of optical paths, storage of excess pigtails and protection of optical cables, etc. The three-in-one fiber optic distribution frame plays an important role in the safe operation and flexible use of the optical fiber communication network. It can realize the fusion, deployment, fixing and storage of optical fiber links, as follows:</p><p><br></p><p>1. Welding</p><p>The three-in-one fiber optic distribution frame can fuse the optical fiber led out of the optical cable and the tail cable, coil and store the excess optical fiber, and protect the fusion splice.</p><p><br></p><p>2. Fixation</p><p>When the optical cable enters the triple-play fiber optic distribution frame, the outer sheath and the reinforcing core of the optical cable can be mechanically fixed, ground wire protection components can be added, and the optical fibers can be grouped and protected.</p><p><br></p><p>3. Deployment</p><p>The pigtail cable (with optical fiber connector) can be plugged into the optical fiber adapter to realize the optical path connection with the optical fiber connector on the other side of the optical fiber adapter. The optical fiber adapter and optical fiber connector can be flexibly inserted and removed; the optical path can be freely allocated and tested.</p><p><br></p><p>4. Storage role</p><p>The three-in-one fiber distribution frame can provide storage for various cross-connect cables in the rack, so that they can be neatly and regularly stored. The three-in-one fiber optic distribution frame has an appropriate space, which can make this part of the connection cable clear and easy to adjust, and can meet the minimum bending radius requirements.</p><p><br></p><p>How to install the three-in-one fiber distribution frame?</p><p>Because the three-in-one fiber optic distribution frame can realize the connection, distribution and scheduling of the trunk optical cable and the branch optical cable, it is widely used in optical fiber access network lines and CATV network line projects. So how to install three-in-one fiber distribution frame? There are two installation methods for the three-in-one fiber optic distribution frame, one is floor installation, and the other is overhead installation.</p><p><br></p><p>1. Three-in-one fiber distribution frame installed on the ground</p><p>Before installing the triplex fiber optic distribution frame, first plan the placement of the triplex fiber optic distribution frame, and reserve it on the planned ground (prefabricated cement basic) according to the size of the triplex fiber optic distribution frame 4 M12 anchor screws (each anchor screw occupies about 150mm); then start to install the triplex fiber optic distribution frame: first open the triplex fiber optic distribution frame door, put the bottom Pull out the two latches, and open the three-in-one fiber distribution frame base panel; then place the three-in-one fiber distribution frame in the planned position, tighten the anchor screws in the base with nuts, and finally Close the three-in-one fiber distribution frame base panel, insert the plug, and lock the panel.</p><p><br></p><p>2. Overhead installation of three-in-one fiber distribution frame</p><p>The first step of the installation is also to plan the placement of the triple-play fiber optic distribution frame, then reserve 4 φ13 holes in its planned location, and finally install the triple-play fiber optic distribution frame.</p>
