Optical module TX and RX ports
It's commonly understood that a standard SFP module comprises two ports: Transmit (TX) and Receive (RX). The components housed within the Transmitter Optical Sub-Assembly (TOSA) facilitate the transmitting function, while those within the Receiver Optical Sub-Assembly (ROSA) handle. When designing optical networks, understanding the TX/RX power range is vital for ensuring optimal performance and long-term reliability. The TX (transmit) and RX (receive) power levels significantly affect everything from signal strength to transmission distances and the overall optical power. A direct and convenient measurement tool that measures the actual optical power at the fiber end face. SFP modules are small, hot-swappable devices used in both telecommunications and data communications. Standardized by the Multi-Source Agreement (MSA), SFPs are interoperable across different brands. SFP modules are transceivers that can be used to connect fiber optic cables in a network.

Does a high-voltage power line interfere with an optical cable
Because light isn't an electric current, fiber is immune to electromagnetic interference (EMI) and radio frequency interference (RFI). You can run a fiber cable right next to a high-voltage power line, a microwave oven, or an MRI machine, and it won't pick up noise. When a communications cable runs parallel and in close proximity to a power cable, these magnetic fields induce unwanted currents—a phenomenon known as inductive coupling—into the sensitive data conductors. This induced noise can. Frequency used to transmitt optical signals is about 1000 times greater than the power frequency. If you can't find a way, make one. A short section of cable next to a power line won't cause big problems, but don't run both through a long conduit right next to each other. An outdoor light will not affect the fiber or the light traveling through it. The first patents on such cables dates.
