Hello everyone this is my first post


Ive got an issue that I just cant seem to solve. I hope you guys could help me out. My room came pre wired with 2 cat5e ports. 1 is for the internet the other one is used for the telephone.

Now I am getting an HD cable connection that also uses cat5e cables.

I was wondering if the cat5e cable used for my internet connection can also carry the signal for my TV. I've read some where that an internet connection below 10 mpbs only uses half the stranded wires in the cat5e cable. So could the other half be used to carry the signal of the HDTV via a splitter?

So my plan was to have

2 cables( 1 internet and 1 HDTV) ---> Y splitter ---> 1 wire (in the wall) ---> Y splitter --> 2 wires out to my room. (One connected to the TV and one connected to my TV.)

Do you guys think this is possible? or do I have to drill a hole in my wall to get the cat5e for the HDTV?

Thank you for your time!

I bet that what you really need is an ethernet switch, but I can't be sure. What exact TV service are you getting? I am not familiar with a commercial TV service that distributes via cat5.

Are you saying your HD TV connection uses ethernet for the TV singal, or it uses ethernet to get on the internet? To get internet onto the tv and the computer you would just get an ethernet switch. A 5 port gigabit switch can be found for less then $20.

FYI it is 100mbps or slower only uses 4 of the 8 wires in a cat5 cable. 1000mbps (gigabit) uses all 8. To split the cable you would need a splitter on both ends.

You likely could convert the one for the phone to rj45 if you do not use the phone line.

You can use pair splitters like you describe to break a cable into 2 but each will be limited to 100m. Some of the automdix has issues when you split the pairs so you may have to use cross cables.

Now that low ended managed switches have come down in price you are better off "splitting" the cable using vlan tags. This let you carry multiple networks over the same cable and they get a total 1g to share rather than each have 100m.

A managed switch should work as long as the HD cable is some standard ethernet. Now if it is not normal ethernet then you need to confirm that it will run over 2 pair. For example those cable that carry HDMI over ethernet actually need all 4 pair. Some want 2 full cat6 cables. They run a totally incompatible form of signaling than ethernet.

It turns out the TV signal needs 6 wires which just leaves enough for the 2 cable needed for the phone line. Brown and striped brown.
apperently the contractor used cat 5e cables for the phone lines. So we ended up using that one

thank you everyone!
