Check the internal condition of the optical cable
Improper pulling or tension – Over-stretching during installation breaks internal fibers. Rodent attack – Common in underground or rooftop routes where unarmored cables are exposed. They deliver enormous volumes of data through strands of glass thinner than a human hair. However, when these delicate fibers are bent, crushed, or exposed to harsh environments, the light signal weakens — resulting in high. One of the most common signs indicating a faulty optical cable is a loss of signal or a weak, intermittent signal. If you notice that your audio or video suddenly cuts out or becomes distorted, it may be indicative of a problem with your cable. Examine the exterior of the fiber-optic cable for any visible signs of damage, such as cracks, kinks, or cuts.

How to check the type of port optical module
Execute the following command to view detailed interface and optical module status: show interface <interface-type> <interface-number>Execute the following command to view detailed interface and optical module status: show interface <interface-type> <interface-number>When optical modules operate on a switch, it is usually necessary to read the module's internal information to understand its working status—such as connection status and real-time metrics like optical power and temperature. Additionally, identifying module information helps detect coding. Optical module identification and status monitoring are essential daily tasks for network engineers maintaining Cisco switching systems. The Cisco Small Business Series Switches allow you to plug in a Small Form-factor Pluggable (SFP) transceiver in their optical modules to connect fiber optic cables. SFP modules are commonly used in networking equipment, such as switches, routers, and network interface cards, to provide flexibility in connecting different types of optical and electrical interfaces.
