Fiber optic cable is normal but optical module is not working
One of the common issues seen when dealing with SFP troubleshooting is when the SFP module is simply not detected by the switch. The first check is to confirm physical connections. Check that the module sits correctly in the port and that the fiber cables are connected. Quick reference for interpreting Digital Optical Monitoring (DOM) values on fiber optic modules (SFP, SFP+, QSFP, etc), identifying acceptable, caution, and unacceptable levels, and general issue troubleshooting examples. The suggested ranges is meant to cover a general ground across different. SFP issues are among the most common and frustrating problems in fiber optic and Ethernet networking environments.

What is the optical fiber cable in the middle of the iron tower
OPGW is optical fiber composite ground wire. This layer of aluminum and steel wires serves to connect the tower to the ground. All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission. OPGW fiber optic cable, or Optical Ground Wire, is a type of cable designed to serve dual functions: it acts as a ground wire for power transmission lines and as a medium for transmitting data via optical fibers. Refer to the installation technology and management of power company's aerial transmission. But today, we use OPGW as shield wire /sky wire / ground wire. It is designed to replace traditional static / shield / earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes.
