With the rapid development of global information technology, urban subways are becoming more and more digital and intelligent. The construction of the subway integrated wiring system as an information infrastructure is also essential. The integrated wiring system of the subway belongs to the communication transmission system.
The transmission is the most important subsystem in the communication system. Its function is to provide the control center to the station (vehicle section/parking lot) and the station to the station (vehicle section/parking lot) for each subsystem of the communication system and other electromechanical systems. This information transmission platform has high requirements for safety and reliability. The transmission system should be able to transmit various information between the operation center and each station, the signal section of the depot, the comprehensive maintenance building, the parking lot, and the substation. In addition to provide the required business interfaces, such as audio 2 / 4 line, E1, RS422, 10/100/1000M Ethernet interface. Each node of the communication network able to provide a point-to-point straight-through, point-to-multipoint shared and other channel type.
The transmission system forms a loop network through fiber optic cables laid in the tunnels on both sides. When the transmission equipment in the loop fails or the cable disconnected, the transmission loop will automatically leave the faulty equipment and form a new loop to continue working, then issue a fault alarm message.

Our company provides the following services for the subway project: to establish a set of advanced and complete communication network cabling systems, including access and wiring for data, voice, image, control and other application systems. The inter-network interconnection solution not only needs to meet the current use of Shanghai subway, but also needs to consider the future development of the network, so that the system can achieve flexible configuration, easy management, easy maintenance, and easy expansion.

Based on the above characteristics of the subway integrated wiring system, we offer professional and complete solutions for fiber-optic and copper cable shielding and wiring systems.
