PIN photodetectors are vital components in optical communication systems, converting optical signals into electrical signals for further processing. The name "PIN" comes from the three distinct layers of semiconductor material that form the device: the P-type, Intrinsic (I), and. As a core component of optical transceiver modules, these devices ensure seamless high-speed data transmission across networks.

A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. Instead of running a separate fiber strand to every home or office, a PON shares a single fiber using optical.

Because relay protection plays a significant role in the entire power system, optical fiber communication is generally used as the physical transmission channel of the relay protection device to protect the signal. In this paper, the main technology of optical differential protection, in the process of 6 KV power distribution system reform is how to apply this situation are introduced in detail, at the same time, a detailed description of the relative performance for the optical fiber differential protection. Optical fibre measurement is advancing, vari ous techniques in optical signal pro cessing are still under development and therefore there is still much research to be carried out into the applicability to the power industry.
