Control cable

Is it possible to request the replacement of control cables with fiber optic cables, for things such as inverter control signals, etc.?

Of course this won’t work. First, you need to understand the concept of optical fibers: optical fibers transmit signals in the form of light pulses, using materials such as glass or acrylic as the medium for signal transmission. It consists of a fiber core, a cladding, and a protective sheath. Fibers can be divided into single-mode fibers and multi-mode fibers. Single-mode fiber provides only one optical path; it is more complex to manufacture, but it offers greater communication capacity and longer transmission distances. Multimode fiber uses multiple optical paths to transmit the same signal, with the transmission speed being controlled by the refraction of light. The optical fibers used in computer networks fall into the following categories: (1) 8.3 pm core/125 pm cladding, single-mode ; (2) 62.5um core/125um jacket, multimode ; (3) 5OPm core/125pm shell, multimode; (4) loopm core/140pm shell, multimode. Additionally, control cables generally refer to those used for powering equipment and instruments as well as for signal control; they are signal and control wires applied in switch control, instruments, protection devices, and other such applications! It is primarily responsible for signal transmission, mechanism operation, and component control! Of course, the control signal of an inverter can be an analog signal or one transmitted via communication, but fiber optics cannot be used!

Excuse me, upstairs – why can’t fiber optics be used? I think it can be transmitted with a photoelectric converter!

Do you think it’s necessary to use fiber optics to control an inverter? Whether considered from an economic perspective or in terms of control methods, I think it’s not a good idea

For long-distance transmission within a factory, digital signals can be transmitted using optical fibers, which serve as a replacement for network cables. The controllers don’t need optical fibers for transmitting signals; instead, optical fibers are used to connect the central control room to the controllers in the control cabinets. The I/O cards use ordinary control cables when installed at the site
