how do cat6 patch panel Piggyback works ?

One commonly used solution to cable-length limitations is something called HDMI over Cat 6. ­Steven D’Addone, co-owner of Intra Home Systems in New Jersey, an installer of high-end audiovisual 4 port HDMI switch systems, swears by the technology. “We only run cat6 patch panel,” he says. Here’s how it works: A video source, such as an HD cable box, is connected to a small device­­—a “balun,” in the parlance of the trade—with a short HDMI cable. The balun usually takes the form of a small, router-like box or a wall plate. Its job is to pass the HDMI signal along to one or more cat5e cable or Cat 6 cables. (These are the same cables used to wire Ethernet networks—Cat 5e is a more common cable, but the ­newer Cat 6 standard is preferred by AV installers for its higher bandwidth.) At the receiving end, a similar box passes the signal back onto an hdmi wall plate, which then connects to your display. Now, all HDMI over cat6 patch panel baluns are not created equal. Some crudely bridge the HDMI and cat6 patch cables by relying on the signal power of the Barrier Terminal Block original video source—this limits the range considerably. Others compress and then decompress the HDMI signal, but this can cause hardware compatibility problems. D’Addone recommends a third type of system. “What seems to be the most reliable are cat5e network cable products that are high-­bandwidth and powered on both sides,” he says. These boxes, which can be found for about $100 each, create a direct bridge between HDMI and a pair of Cat 6 cables, but provide extra power to ensure the signal can travel distances up to 150 feet. Best of all, powered HDMI over Cat 6 preserves the quality of video and audio ­signals. And given the low cable price—about a dollar per 10 feet online—HDMI over Cat 6 makes the most economic sense for longer throws.

Industry-standard patch panel's definition

patch panel management subsystem is the most important component, is to achieve two vertical lines and horizontal cabling subsystem cross-connect hub. patch panel is usually industrial terminal block installed in a cabinet or on the wall. By mounting accessories, patch panel can meet the full range of UTP, STP, coaxial cable, fiber, audio and video needs. Commonly used in network engineering has UTP patch panels and fiber optic patch patch ISO / IEC 11801: 2002 patch - apply to the jumper wires connected fixtures. It enables the system to move and change the wiring is more convenient. ANSI TIA / 568-B patch panel - easy to manage cross-connect system consists of pairs of connectors  composition. The effect of UTP patch panel will be twisted in the management of cross-connect subsystems used in each room and the distribution line of the main wiring. Many models UTP patch panels, each vendor has its own Barrier terminal block product line, and the corresponding three categories, Category 5, Category 5e, Category 6 and Category 7 cables were different sizes and models, in specific projects , you should refer to the product manual, be configured according to the actual situation. Fiber optic patch panel's role is in the management of the cable will be connected subsystems, usually between the main line and distribution lines between each.

Here are some common patch panel and a reasonable match in the practical application between them.

The late eighties, integrated wiring system has just entered China, then the information transmission rate is very low, only three types of cabling systems (16MHz) products, wiring Barrier terminal block system mainly uses 110 fish skeleton patch panels, mainly are 50 pairs, 100 pairs 300 pairs, 900 pairs of wall-mounted several, while supporting the use of cables; drawback is more troublesome cable termination, termination should not be a one-time change, no shielding products, termination tool more expensive, inconvenient maintenance upgrade. With the continuous improvement of network transmission rates, there have been five cabling system (100MHz), network interface RJ45 gradually to unity, patch panels for terminating cables to transmit data using 19 inches RJ45 patch panel port 110, Such patch back into line using 110 Termination, all RJ45 ports for front jumper wires, which are divided into 24, 36, 48, 96 several, all 19-inch rack / rackmount installation, the advantage of small size, high density, relatively simple and can be repeated termination termination, mainly for the four pairs of twisted-pair termination, shielded products; drawback is due to the line cables in the distribution cat6 patch cable rack on the back of the line termination, and qualifying jumper complete patch management front, so the maintenance and management more difficult; Because the port is relatively fixed, regardless of the number of desktop information to manage port number must be a multiple of 24 and 36 according to the port to configure, the vacancy caused by the wiring ports and waste, not flexible; another relative price 110 fish skeleton patch expensive.

MDF industry standard definition

Patch management subsystem is the most important component, is to achieve two vertical lines and horizontal cabling subsystem cross-connect hub. MDF is usually installed in a cabinet or on the wall. By mounting accessories, patch panels can be across the board to meet UTP, STP, coaxial cable, fiber, audio and video needs. Commonly used in network 12 port patch panel engineering has UTP patch panels and fiber optic patch patch ISO / IEC 11801: 2002 patch - apply to the jumper wires connected fixtures. It enables the system to move and change the wiring is more convenient. ANSI TIA / 568-B patch panel - easy to manage cross-connect system consists of pairs of connectors composition. Twisted role in the management of patch panel in the twisted-pair cross-connect subsystems used in each room and the distribution cat6 patch panel line of the main wiring. Many models UTP patch panels, each vendor has its own product line, and the corresponding three categories, Category 5, Category 5e, Category 6 and Category 7 cables were different sizes and models, in specific projects , you should refer to the product manual, be configured according to the actual situation. Fiber optic patch panel's role is in the management of the cable will be connected subsystems, usually between the main line and distribution lines between each.

12 port patch panel features are as follows

Fully modular design, full front operation, welding and wiring in one set, to maximize the high-density, can be installed on 19-inch standard rack, suitable for ribbon and non-ribbon cable, you 12 port patch panel can snap-in installation FC, SC, ST and LC, and other adapters, adapter and device access installation at 30 ° cards, both to ensure the bending radius of curvature of the jumpers and avoid the laser burns the human eye, easy to operate, perfect protection, cable and tail fiber all have more 24 port patch panel than 2m disk storage space. 12 port patch panel is a HPN Series fiber optic splice wiring unit body, which makes the maximum end of the cable into the connection and wiring of high density, while for the cable provides the best protection, and can be based on need as a stand -alone unit mounted welding wires used on standard 19-inch rack
