Structured cabling system, as the inevitable foundation of the development of the network era, has covered almost all buildings at a rapid speed in the past two decades.

 

The relevant standards for the development, engineering design and installation of structured cabling products are well established.

 

After the installation of the structured cabling system is completed, a lot of drawings and point records are left to the user. Faced with hundreds of wiring ports in the equipment room, it is often difficult for users to establish and implement a set of efficient tracking records. maintenance program.

 

After the network has been in operation for a period of time, especially after some personnel changes have occurred, it is difficult to maintain a clear grasp of the information on the existing cabling system. Once a problem occurs, network managers will spend a lot of time and energy to find the various components of the problem link on site.

Electronic intelligent wiring system is a major technological leap in the field of structured wiring. It has experienced nearly ten years of development and is now becoming more and more mature.

 

It elevates the traditional cabling system, which is positioned on passive infrastructure, to a higher level, and makes up for a missing key link between the physical layer and the network layer, so that network managers no longer need to go through cumbersome and unreliable paper query procedures. Obtain realistic network connection status reports, thereby improving the work efficiency of network management and reducing the damage caused by system downtime to the enterprise.

 

Structured Cabling System

At present, the mainstream electronic intelligent wiring systems on the market are mainly divided into two technical schools, namely switch detection and link detection.

 

The principle of switch detection technology is that an unmoved switch is integrated inside the modular (optical/copper) socket, and the plug-in and pull-out actions of the modular (optical/copper) jumper directly trigger the opening and closing signals of the switch. After the collection, it is transmitted to the background database software, so as to realize the real-time recording of the change of the jumper connection property.

 

The principle of the link detection technology is to add a copper wire for detection in the modular (optical/copper) jumper, and the plugging and unplugging actions directly cause the wire to connect to the sensor metal sheet integrated in the modular (optical/copper) socket. , the generated loop signal is collected by the relevant signal acquisition equipment and then transmitted to the background database software, so as to realize the real-time recording of the property change of the jumper connection.

 

The communication methods of the two technologies are independent of the application network transmission, that is to say, they will not interfere with the business network running on the wiring system, and the opening and closing of the electronic intelligent wiring system will not affect the normal operation of the user network.

 

In the installation stage, the systems supported by the two technologies must be installed with a dedicated electronic distribution frame and equipped with a certain number of signal acquisition units. The switch detection type system can use ordinary jumpers to complete cross-connection, while the link detection type system must be Use a dedicated electronic jumper (commonly known as "ninth-pin jumper").

 

In the software system installation stage, the systems supported by both technologies must go through the process of manual data entry. The difference is that the switch detection type system must be completed before the jumper is loaded, while the link detection type system must be completed before and after the jumper is loaded. can proceed.

 

In the daily use and maintenance stage, the systems supported by the two technologies support the monitoring and recording of single jumper insertion and removal. However, for the change of batch jumper connection attributes, the switch detection type system must define the order of rules in advance and strictly follow this Sequential operation, while the link detection system can randomly complete batch insertion and removal operations, especially some jumper changes across cabinets.

 

In the disaster recovery stage, the link detection system can automatically scan the connection relationship of all ports within the monitored range after the disaster, and automatically generate change records by comparing with the pre-disaster state table to ensure the consistency of the existing records and the on-site conditions. , while the switch detection system can only recover to the last valid state before the disaster, and needs to be revised manually to ensure the consistency of the database and the on-site conditions.

 

Through the above analysis and comparison, we can see that the two technical solutions have their own advantages and characteristics, and users can choose the most suitable system according to their own needs.
