Fiber optic distribution frame (rack type)
Conventional port number: 24 ports, 48 ports
Use environment: inside the standard cabinet
Fiber optic distribution frame is used to connect vertical backbone and horizontal fiber optic cable, generally 1U height 19 inch rack type, usually at least 12 ports.
Fiber optic Terminal box
Conventional port number: 8 ports, 12 ports
Use environment: wall-mounted or desktop
Fiber optic terminal box is usually placed at the end of the horizontal fiber optic cable, from the fiber optic terminal box through the coupler out of the optical patch cord connected to the device, is the nearest terminal (switching equipment or PC) a plugging point, usually 8 ports.
Fiber optic splitter box
Conventional number of ports: 24 ports, 48 ports
Use environment: inside the building
Fiber optic splitter box is used for outdoor, building or indoor connection of backbone and wiring fiber optic cable interface equipment. Commonly used in FTTH all-optical network of optical network laying. It is also a small box that we can often see in our daily life in the hallway.
ODF (Optical Distribution frame)
Conventional number of ports: 12-1440 cores
Use environment: computer room, regional wiring, residential FTTH and other large-scale fiber optic cabling.
ODF (Optical Distribution frame) fiber optic distribution frame is designed for fiber optic communications equipment, fiber optic wiring equipment, with cable fixing and protection functions fiber optic cable termination function, cable transfer function, fiber core and pigtail protection function. The equipment configuration is flexible, easy to install and use, easy to maintain, easy to manage, is the fiber optic communication cable network terminals, or relay points to achieve the row of fiber, fiber patching and access to the essential equipment.
To sum up, fiber optic distribution frame, terminal box, fiber distribution box, ODF distribution frame difference is mainly in two points: 1, the number of interfaces is different. 2, the use of different environments. Do not look at their four seem very complex, the actual role of the real coupler is a bracket, they are not involved in the data transmission. Just according to the application environment and the different ports required to serve the various places that need them.
