Rat chewed through ethernet cable

Hi all,

 

So checked in on my router the other day and see a rat has chewed through about 50% of one of the cables. My question is, how the heck am I still getting full speeds from it? Don't worry, already got a replacement cable but still using it lol

Do you have >100Mbit Internet? If not it might have chewed through the correct pairs where 100mbit is still possible.

Yeah I think it is. Okay, thought it used the whole cable.

Eh...it's a little complicated.

 

Gigabit Ethernet is bi-directional. All eight wires send & receive. You can do 100mbps with two pairs (four wires) though my knowledge is limited here. I'm not sure if two pairs is also bi-directional or half-duplex or if to send and two receive.

 

Someone will fill in the blanks for me.

100 meg is on the orange and green pairs only. Gigabit uses all the pairs. Not exactly kosher but in a pinch you can usually get away with 2 100 meg down one cat x cable or 100 meg with a line or two for DSL, POTS, fax or similar.

 

PoE depending on type can be on those other spare pairs, so can lead to a device that has power but no data or vice versa, data but not it's PoE power (usually find out from a wire map or for some devices can use alternative power option to troubleshoot also). Can also get power and data superimposed over each other like with higher power or gigabit PoE.

 

Anyway long answer is that the pairs crucial for 100 meg are intact enough and not so far out of spec that they still work.

 

Might have been chowing down on that tasty brown pair. 🙂

 

It's surprising what can work and then on the flipside, what doesnt.

Rat knows his twisted pairs!

 

BTW, is that the flat type ethernet cable?

Rat's gone now, lil bastard.

 

Yeah, went with a flat cable since they're easier to make cleaner runs with.

Also easier to chew through, apparently. 😉
