Switch network port is working but optical port is not
Move the cable to a known good port to troubleshoot a suspect port or module. The show module command can indicate faulty, which can indicate a hardware problem. This document applies to Catalyst switches that run on Cisco IOS® System Software. I have an issue with some EX2300 series images where the optical ports allow trafic, but the led stay. It acts as a central hub, ensuring that data packets are delivered accurately and quickly to their intended recipients. Power over Ethernet (PoE) is a means of supplying electrical power from a switch port over ordinary data cabling to a connected powered device (PD), such as a VoIP handset, IP camera, or wireless access point.

Two network ports of the optical switch
Switches come in three types: those with purely Ethernet ports, those with purely optical ports, and those with a combination of both. The mainline of the fiber optic LAN directly connects to the switch, then to the router. Optical ports on switches typically accommodate optical modules for transmitting data via fiber optic cables.

Does a 24-core optical cable have 24 cores
The design of 24 Cores cables is based on the principle of maximizing capacity while minimizing size. Each fiber is color-coded for easy identification during installation and maintenance. Of course, this is a general situation, and specific words may consider according to the following criteria. Fiber core count defines the maximum number of optical terminations or distribution points that a fiber enclosure can support. The optical fiber elements are typically individually coated with layers and contained in a protective tube suitable for the environment where the cable will be deployed.
