This invention provides an optical telemetry and control method, apparatus, system, and electronic device. The method is applied to a remote access unit configured with a preset physical shielding structure, and includes: receiving a downlink control signal sent by a telemetry and control center via optical fiber; performing radio frequency filtering on the downlink control signal; up-converting the filtered signal, amplifying its power, and then transmitting it; receiving an uplink radio frequency signal transmitted by a skid; pre-filtering the uplink radio frequency signal; down-converting the filtered signal, performing electro-optical conversion, and then transmitting it via the optical fiber. This invention enhances the stability of the remote access unit in environments with strong electromagnetic interference and strong magnetic fields through a triple design of optical domain transmission, radio frequency filtering, and magnetic shielding, achieving highly reliable, low-latency telemetry and control communication, and overcoming the application limitations of traditional wireless technology in extreme environments.
