2400 Mhz splitter

qwqwek · 13-10-2008, 19:54

Guys,

I would like to split my cable connection to have internet in two rooms. I have bought a 1 to 4 splitter in the frequency range of 5 to 2400Mhz. However, the VM supplied splitter only goes upto 1000Mhz. Is it ok to use my 2400Mhz splitter without degrading the signal quality?

I was planning to use only 2 ports of this 4 port splitter. Is it ok to leave the remaining 2 as it is?

Cheers

Prey explain how you will get Internet in 2 rooms, Do you have 2 modems ?

What your trying to do won't work. The work you propose doing is against the virgin media terms and conditions and also you can only get one modem per connection.

Only way of getting the internet on more that one device and/or more than one room is going to be get a router.

Actually, I have two modems which i have collected over the years from VM when i moved house. But, no i wasnt interested in using both my modems (dont even know if that would work).

On the contrary I was only planning to reconnect my modem in the other room whenever i need internet there. Hey, but nobody answered my question, is it ok to replace the 1000 Mhz splitter with 2400 Mhz? If not, i wont bother with this.

VM network doesn't go near 1000MHz so pointless using a 2400MHz splitter.

And no, it's not good to leave 2 ports of the splitter open, it'll increase insertion loss on the signal and risk noise ingress onto the cable network I'm afraid.

Thanks for the post Broadbandings.

Does i mean that 2400Mhz splitter is a better spec. than the 1000Mhz one.

How can i close off the unused ports?

Btw, are there any 1 to 3 splitters I can buy in the market?

Cheers

Just out of a technical interest from this post... Should unused ports/cable ends be terminated to stop signal bounceback???

BenMcr · 14-10-2008, 09:01

I would say yes.

When Virgn send a modem out via quickstart and include a splitter, they also include a termination cap which they suggest is put on the other socket on the splitter if TV services are not being used

But is it just a dustcap or an actualy electrical terminator?? (and no before anyone starts I'm not talking about summer glau

It's a terminator. Here's one Altis prepared earlier:

Not only will you get microreflections from unterminated cable, it'll also act as an aerial to soak up RF noise from the surroundings, so yes, a terminator to both keep the port / cable RF sealed and soak up signal to prevent reflection is highly, highly advisable.

No, it just means it can carry a wider bandwidth, doesn't mean anything really for the range VM carry and it could actually be poorer at the job, depending on its' construction.

Close off ports with a terminator as above.

A 3 way splitter is indeed available but do bear in mind that all it is is a 2 way splitter with 1 port split again, so 1 port will have 3.5dB loss while the other 2 will lose 7dB. (Signal strength halved = 3dB + additional 0.5dB insertion loss)

I will have to buy these terminators then. Is there any place I can buy them, Maplin?

We like Summer Glau methinks as you mentioned her

Kymmy · 14-10-2008, 17:23

I presume the terminator impedance will 75R to match the cable??

BTW I only asked as I'm old enough to remember 10base-2 and, mind you I also remember token ring

BenMcr · 14-10-2008, 20:31

Slight OT, was that that twist on networking cable where all the computers were in a line and you needed caps on each end otherwise it didn't work?
