Based on what you’ve mentioned, if the existing cable length is insufficient, it is indeed necessary to use a terminal cabinet to extend it. Whether wiring is required for each endpoint depends on the system’s requirements and the existing wiring structure. Using fiber optics for transmission is a good way to save space and improve transmission efficiency, especially for long-distance transmission. Regarding your question about whether a single fiber optic cable can suffice for transmission in such cabinets, it depends on your system configuration and requirements. In modern industrial communications, there are indeed devices and cabinets that use optical fibers for data transmission, which allows for a significant reduction in complex cable wiring. As for the “Leisi OCS cabinet,” if it refers to a control cabinet that makes use of an OCS (Operator Control Station), such a system design generally supports various communication methods, including fiber optic communication. To determine whether this function of transmitting data via a single fiber optic cable is supported or feasible, it is best to check the device’s technical specifications or consult the manufacturer. It is recommended that you contact the specific equipment supplier or a professional system integrator, as they can provide more detailed advice and technical support to ensure the proper modification of the system and the realization of its functions. .

The central switch has versions with optical modules; replacing them should solve the problem

The key lies in the reason for the relocation. If the original cabinet room does not meet the specifications (for example, it fails to satisfy explosion-proof requirements) and needs to be relocated entirely, then wiring boxes must be added to facilitate proper wiring. If the existing cabinet room and cabinets can be retained and only new cabinets need to be installed elsewhere, then remote I/O stations or expansion cabinets can be considered; these should be connected via fiber optics. It is important to note that only \"one\" fiber optic cable should not be used, as this could lead to the cable being severed due to construction work or other mechanical damage, thereby causing the system to fail. Redundant networks generally require the installation of two fiber optic cables; it is common to place them in locations that are separated by one day’s distance from each other or on opposite sides of the conduit. Even if one cable is damaged, the system’s operation remains unaffected. Additionally, despite having different paths, the two fiber optic cables should have as similar lengths as possible to ensure network stability.
