Question : Problem: Fiber Cable  vs  Cat 5 or 6 Cable

Hi,

1. There are a Power Failure in a certain part of a city
2. Most companies are affected
3. A company mostly used FIBER CABLE from a Core switch to other switches
4. I saw in other company that they used the CAT 5 or CAT 6 to connect from a Core Switch to other switches, and they are very STABLE (after the power failure)
5. Related to # 3 above: i) I saw (after the "power failure"), the switch which collected a group of network ports (in a certain area) ARE NOT STABLE. All the connection at that area are IN an OUT (5 minutes OK and another 5 minutes NOT OK) (This switch is connected to the Core Switch with fiber cable)
6. My question: Is it TRUE that the CAT 5 or 6 is much more STABLE than fiber cable after the Power Failure.
7. Thanks

Tjie

Also some times if the switch is not protect with surge protectors some of the GBICs or SPF get damaged.
