2960s limitation of ethernet cable length

hi all,

i just noticed today that i have a client in my manufacturing with about 300 feet connected to my switch, a laptop on the generator maintenance.  how far is the guide line i can have for a switch like 2960s?  i think i had this on my exam before in CCNA that a long cable could slow down the network.

Also, is there a utility that i could use if my switch are having those slow connectivity.

thanks for any comment you may add, more power y'all.

Copper Ethernet standards call for up to 100 meters.  If the environment has much electromagnetic "noise", you might not make that distance unless you have well shielded cable.  If you run Ethernet on "better" cable than it needs for the Ethernet "speed", you can sometime eke out some more distance.

The 2960 shouldn't matter much, vs. any other device.  Longer distances usually degrade the quality of the received frame, and if it's corrupted, slows the effective transfer speeds as frames need to be retransmitted.

As switches regenerate frames, an unmanaged 4 port switch, place in-line half way, might be an inexpensive solution to improve end-to-end transmissions.

2960s limitation of ethernet cable length

I've seen copper cabling run >100 metres but the speed you'll get is 10 Mbps only.  100 metres guarantees you have 100 Mbps or 1 Gbps.
