Optical Fiber Distribution Frame, Terminal Box, Distribution Box, ODF Distribution Frame
The actual distribution frame is similar, and it is applied in different places according to different use environments and ports.
Optical fiber distribution frame, terminal box, fiber distribution box, ODF distribution frame are some of the commonly used connectors in optical fiber connection
1. Fiber Optic Terminal Box
The optical fiber terminal box is the terminal connector of an optical cable. One end is an optical cable and the other is a pigtail. It is equivalent to a device that aligns an optical cable into a single optical fiber. It is installed on the user's optical cable terminal box of the chassis. Its function is to provide Fiber optics provide mechanical protection and environmental protection, and allow proper inspections to maintain the highest standards of fiber management. Optical fiber and optical fiber fusion splicing, optical fiber and pigtail fusion splicing, and handover of optical connectors.
Commonly used ports are 8 and 12 ports.
Wall and desktop use.
The optical fiber terminal box is usually placed at the end of the horizontal optical cable. The device connected from the optical fiber terminal box through the optical jumper connected to the switch is the nearest plug-in point to the terminal (switching device or PC), usually 8 ports .
2. Optical fiber distribution frame
The optical fiber distribution frame (ODF) is used for the formation and distribution of the backbone backbone optical cable in the optical fiber communication system, and can easily realize the connection, distribution and scheduling of the optical fiber line. The degree of integration through the network is getting higher and higher, and there are several hybrid distribution frames that integrate ODF, DDF, and power distribution units into one. It is suitable for small and medium-sized distribution of fiber-to-community, fiber-to-building, series modules and wireless base stations Wire rack system.
Optical fiber distribution frame is mainly divided into 12-port fiber distribution frame, 24-port fiber distribution frame, 48-port fiber distribution frame, 72-port fiber distribution frame, 96-port fiber distribution frame, and 144-port fiber distribution frame.
3. Fiber distribution box
The fiber distribution box is mainly used for FTTB. In FTTH, the problem of insufficient fiber core is an optical splitter and several fiber fusion disks, which are usually hung above the stairwell of the residential area or in the green belt of the residential area.
24 or 48 conventional ports;
Generally used in corridor weak current wells;
Sometimes it is necessary to add an optical splitter module.
4, ODF distribution frame
Optical fiber distribution frame (Optical Distribution Frame) is used for the formation and distribution of the backbone backbone optical cable in the optical fiber communication system, which can easily realize the connection, distribution and scheduling of optical fiber lines.
ODF main features: full adjustment design, full frontal operation; integrated fusion and wiring in one, interchangeable high density; can be installed on a standard 19-inch rack; suitable for ribbon and non-ribbon optical cables; card Various adapters such as FC, SC, ST, and LC are installed by connection; adapters and equipment are installed at 30 ° with snap-on connection, which not only ensures the bending curvature of the jumper, but also avoids laser burns, which is convenient for operation and complete protection; And pigtails have a disk storage space of more than 2m.
Port 12-1440 core;
Mainly used in computer room, small area, FTTH fiber wiring;
In summary, the functions of the above high-level racks can be collectively classified as:
①Fixed-function optical cables enter the rack, they must be mechanically fixed when they enter the outer sheath and reinforced cores. They must be equipped with ground wire protection components, processed for end protection, and transferred optical fibers for grouping and protection.
② Splicing function, splicing the optical fiber from the optical cable with the pigtail cable, coiling the excess optical fiber for storage, replacing the splicing connector for protection;
③ The adapter and connector can be inserted and removed flexibly; the optical path can be freely deployed and tested;
④ Appropriate space and method meet the requirements of minimum bending length.
In essence, the distribution frames are similar, and the real function is the reorganizer. They do not participate in data transmission themselves, and are applied in different places according to different use environments and ports.
