The concept of 24 port patch panelcat

Patch management subsystem is the most important component is to achieve Cat3 keystone jack lines and two horizontal cabling subsystem cross-connect hub. MDF is usually installed in a cabinet or on the wall. By mounting accessories, 24 port patch panelcat panels can meet the full rj11 telephone jack of UTP, STP, coaxial cable, fiber optic, audio and video needs. Commonly used in network engineering twisted pair patch panels and fiber optic patch panels patch panels.

24-port patch panel panelcat description:

1, environmental requirements
1.1 Working temperature: 5 ℃ ~ 40 ℃; Relative humidity: not more than 85% (30 ℃ pm); Atmospheric pressure: 70 ~ 106Kpa; storage humidity: -25 ℃ ~ +55 ℃.
2, the electrical performance
2.1 Working speed: 2Mbit / s, 8Mbit / s, 34Mbit / s, 45Mbit / s, 140Mbit / s, 155Mbit / s;
2.2 Characteristic impedance: spring terminal block(nominal value);
2.3 coaxial connector contact resistance; outer conductor is not more than 2.5mΩ, after mechanical durability test its value is not more than 2.5mΩ; inner conductor is not more than 10mΩ, after the mechanical endurance test its value is not more than 10mΩ;
2.4 Insulation resistance: the connector between the outer conductor, insulation resistance between the conductor and the cell sheet metal parts should be rj45 ethernet connector than 1000MΩ, DC voltage measuring circuit is 500V ± 50V;
2.5 Withstanding voltage: the connector between the outer conductor, between the inner conductor and the cell sheet metal parts should be able to withstand a frequency of 50Hz, the effective value of the AC voltage of 1000V role 1min without breakdown, no arc;

12 patch panel mechanical properties

A pull-out force: The coaxial cable connector with anti-cable tensile strength greater than 50N; 
2 Mechanical Durability: coaxial connector plug after 1000, shall comply with the provisions of the line marked PCB spring terminal block and 6.2, and the contact surface of the plating layer is still not expose the base material; 
4 Digital Distribution All parts are made of materials should have anti-corrosion properties, such as corrosion resistance should be done without mini HDMI cable treatment; their physical and chemical properties must be stable; must be compatible between the various materials; 
5 Digital Distribution combustion performance of all non-metallic materials structures shall conform to GB/T5169.7-1985 A standard test requirements; 
6 conductive elastic material should be used bronze, bronze; 
7 conductor coaxial connector contacts inside and outside the region, should be plated an intermediate layer (buffer layer), then gold-cobalt alloy plating thickness.

cat5e patch panel uses

MDF is positioned in front of the central office of information points modular device management. The front of the information point cat6 patch panel into the equipment room after the first into patch panels, patch panels will hit the line modules, patch panels and switches then connect a jumper (RJ45 interface) . Overall, the patch panel is used to manage the device, for example, if there is no patch, direct access to the front of the information points to the switch, so that once the cable problems, faced to rewiring. In addition, the 48 port patch panel management is also a bit confusing, multiple plug may cause damage to the switch port. MDF exist to solve this problem by replacing the jumper to achieve better management.
