How to choose the number of cores in the integrated wiring system? How much is appropriate to reserve? Optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. It is composed of optical fiber, plastic protective sleeve, plastic sheath and other materials. Because of its wide transmission frequency band, large communication capacity, no electromagnetic interference, low price and other characteristics, it is widely used in various industries, such as communication, broadcasting, electric power, railway, military and other communication transmission systems.

In stand-alone office buildings, office buildings, shopping malls, etc., the floor wiring room to the equipment room generally meets the connection of the backbone optical link between the access layer switch and the aggregation and core switches, and reserves a certain amount of optical link redundancy. To ensure the needs of later business expansion. Generally, 0.5-1 times the number of backbone link cores are reserved.

How to choose the number of cores in the integrated wiring system? How much is reserved? The following two items are used as a reference:

1. The *** project, the building has a total of 4 floors, each floor needs 2 access switches, and its computer network is a two-layer structure of the core layer and the access layer. (Only 1 set of network is used for illustration)

1. Single link. If the backbone link is a single link structure, the number of cores of the optical cable laid between the wiring room and the equipment on each layer is 6-8 cores (4 cores are the actual number of cores used, and 2-4 cores are reserved cores);

2. Dual link. The backbone link is a dual-link structure, and the number of optical cable cores laid between wiring rooms and equipment on each layer is 12-16 cores (8 cores are the actual number of cores, and 4-8 cores are reserved). Large-scale parks, schools, factories, commercial areas, etc., not only involve the selection and reservation of the number of optical cable cores in a single-family building, but also involve the reservation of communication links between buildings. subsystem. At this time, under the premise of meeting the requirements of each weak electronic system, the number of cores of the backbone optical link should be 1-2 times the number of cores reserved for the backbone link. The core computer rooms such as the network computer room and the monitoring computer room in the campus should also be considered.

2. The *** park project has a total of 5 independent buildings. One aggregation switch is installed between the weak current equipment in each building. The overall network architecture of the park is a three-layer architecture of core layer, aggregation layer and access layer. (Only 1 set of network is used for illustration)

1. Single link. If the backbone link is a single link structure, the number of cores of the optical cable laid from the equipment room in each building to the network core equipment room is 4-12 cores (4 cores are the actual number of cores used, and 4-8 cores are reserved);

2. Dual link. The backbone link is a dual-link structure, and the number of optical fiber cables laid from the equipment room to the network core computer room in each building is 8-24 cores (8 cores are the actual number of cores used, and 8-16 cores are reserved cores).
