What is ddf wiring frame?

　　DDF is a digital Distribution Frame (Digital Distribution) Frame), which is a specialized wiring equipment used in digital communication systems. The following is a detailed explanation of DDF distribution frames:

　　I. Basic Definition

　　DDF distribution frame is a wiring connection device between digital multiplexing equipment, digital multiplexing equipment and program-controlled switching equipment or other professional equipment. It can manage and connect digital communication equipment, realize the connection and integration of digital code stream.

　　II. Key role

　　Management and organization of network connection: DDF can organize the digital code stream of digital communication equipment into a whole, whether it is a 2Mb/s or 155Mb/s signal, it can be easily terminated on the digital distribution frame, providing great convenience for wiring.

　　Adjustment and transfer functions: DDF can flexibly adjust the connection relationship of fiber or cable to adapt to changes in network topology, thus meeting the needs of network upgrades and maintenance.

　　Monitoring function: DDF can monitor network connection status in real time, helping managers detect and resolve problems in a timely manner to ensure the stable operation of the network.

　　Simplify the management of network connections: The use of DDF can simplify the management of network connections, improve the efficiency of troubleshooting and maintenance, and make the entire network system run more SMoothly.

　　III. Structure and performance

　　Structure: The DDF distribution frame is usually composed of a rack and a digital wiring unit. The rack is a standard 19 "cabinet with a height of 44.45mm. The structure is made of high-quality steel. After the surface of all structural parts is treated with electrostatic epoxy powder, it does not rust, does not deform, has a beautiful appearance and high strength. The digital wiring unit adopts a combined rotating structure, which can be rotated downward at any angle to locate, so as to facilitate the end operation of the cable head.

　　Performance: DDF distribution frame has strict structural design, high-quality metal and non-metallic materials, standard gold plating, and exquisite and strict craftsmanship to ensure stable and reliable product performance. It can support high-speed signal transmission rates and provide stable connection capabilities for digital communication.

　　IV. Application scenarios

　　DDF distribution frame is widely used in digital communication systems, such as telephone switched network, mobile communication network, data communication network, etc. It is suitable for wiring and transfer of digital signals between digital end points, digital multiplexing equipment or programmable switches with a transmission rate of 2~ 155Mbit/s.

　　To sum up, DDF distribution frame is an indispensable wiring equipment in digital communication system. It has multiple functions such as managing and organizing network connection, adjusting and transferring functions, monitoring functions, and simplifying network connection management. At the same time, its strict structural design and high-quality materials ensure the stable and reliable performance of the product.
