Cable laying issues from the cabinet room to the central control room
Thread Content
In current designs, the optical cables running from the cabinet rooms to the central control room are usually laid in a one-top-one-bottom configuration. Are there any design specifications regarding this? Also, is it okay if the redundant optical cables in the TPS3000 system are not of the same length? Will that cause any problems?
HG/T 20573 stipulates that DCS communication networks should have short response times, high reliability, and structural redundancy. The practice of installing cables in one location per day is aimed at improving reliability and ensuring redundancy; it is not mandatory to do this on a daily basis. When conditions do not permit it (for example, if there are no cable trays in the factory), the cables can be laid in different cable trays as well. The shorter the optical cable, the better; generally, there is no difference in data transmission when the lengths vary.
Honey’s instructions recommend a difference of less than 500 meters

In this industry, a focus on detail is essential; the concept of precision engineering requires such an approach day after day. The specific requirements depend on the type of industry and the economic costs involved. There are no strict mandates, but dual redundancy is necessary. Communication between different sections can be achieved through network cables; however, for distances exceeding 350 meters, fiber optics are recommended as they offer greater reliability, faster response times, and less latency, though at a higher cost.
