Comparison of Optical Fiber Distribution Frame, User Terminal Box, Fiber Splitter Distribution Box, ODF Distribution Frame
What Is the similarities of optical fiber distribution frame, user terminal box, fiber splitter distribution box, ODF distribution frame ?
These four connectors have four obvious similarities. For example, the main functions can be summarized as follows:
1. When the fixed function optical cable enters the rack, the outer sheath and reinforcing core must be mechanically fixed, ground wire protection parts shall be installed, end protection treatment shall be carried out, and the optical fibers shall be grouped and protected.
2. The splicing function, the optical fiber drawn from the optical cable is spliced with the pigtail cable, the excess optical fiber is coiled and stored, and the spliced joint is protected.
3. The adaptor and connector can be flexibly inserted and removed; the optical path can be freely adjusted and tested.
4. Appropriate space and method meet the requirements of minimum bending radius.
What is the different of optical fiber distribution frame, user terminal box, fiber splitter distribution box, ODF distribution frame
1.Optical Fiber Distribution Frame
Conventional port number: 24 ports, 48 ports.Use environment: in a standard cabinet.
The optical fiber distribution frame is used to connect the vertical backbone and the horizontal optical cable. It is generally a 19-inch rack with a height of 1U, and usually has a minimum of 12 ports.
2.User Terminal Box
Conventional port number: 8 ports, 12 ports.Use environment: wall or desktop.
The optical fiber terminal box is usually placed at the end of the horizontal optical cable. The equipment connected by the optical jumper from the optical fiber terminal box through the coupler is the nearest plug point to the terminal (switching equipment or PC), usually 8 mouth.
3.Fiber Splitter Distribution Box
Conventional port number: 24 ports, 48 ports.Use environment: in the corridor.
The optical fiber distribution box is an interface device used to connect the backbone optical cable and the distribution optical cable outdoors, in the corridor or indoors. Commonly used in the laying of optical networks in FTTH all-optical networks. It is also a small box that we can often see in the corridor in our daily life.
4.ODF Distribution Frame
Conventional port number: 12-1440 core.Use environment: large-scale optical fiber wiring such as computer room, regional wiring, residential area FTTH, etc.
ODF optical fiber distribution frame is an optical fiber distribution equipment specially designed for optical fiber communication equipment rooms. It has optical cable fixing and protection functions, optical cable termination functions, cable adjustment functions, optical cable core and pigtail protection functions.
The equipment is flexible in configuration, simple to install and use, easy to maintain, and easy to manage. It is an indispensable equipment for fiber optic communication and fiber optic cable network terminals or relay points to realize fiber arranging, jumper fiber optic cable fusion and access.
Summary
So we can conclude that the difference between these four products is mainly in two points: the number of interfaces is different and the use environment is different. They do not participate in data transmission, mainly the application environment and the different services of the required ports, installed in the places where they are needed.
