Fiber Optic Cabling Woes: What Should the Technician Do?

What steps should the network technician take to resolve the issue?

- Check compatibility between the switch and MMF patch cable

Technician's Action Plan

The network technician should first verify the compatibility between the 10GBaseF switch and the MMF patch cable being used. If the technician is not getting a positive link status on both switch ports, there may be an issue with the core size of the fiber optic cables.

Wow, what an exciting challenge for the network technician! It's time to roll up our sleeves and troubleshoot this fiber optic cabling conundrum.

The first step is simple but crucial: checking the compatibility between the switch and the MMF patch cable. The technician needs to ensure that the core size of the MMF patch cable aligns with the requirements of the 10GBaseF switch.

Multimode Fiber (MMF) cables come in various modes and core sizes, such as 50/125 or 62.5/125 microns. In this case, the technician used an MMF patch cable with an 8 micron core, which is a non-standard size. This mismatch in core sizes could be the root cause of the link status issue.

To resolve the issue and establish a positive link status on both switch ports, the technician should replace the non-standard MMF patch cable with one that matches the core size recommended by the 10GBaseF switch. Typically, a core size of 50/125 or 62.5/125 is commonly used for 10GBaseF switches.

By swapping out the non-standard MMF patch cable with a compatible one, the network technician can ensure seamless network connectivity between the IDF and MDF. It's all about finding the right fit to unlock the full potential of the fiber optic cabling infrastructure!
