2400 Mhz splitter
 

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 ?

Re: 2400 Mhz splitter
 

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.

Re: 2400 Mhz splitter
 

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.

Re: 2400 Mhz splitter
 

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.

Re: 2400 Mhz splitter
 

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

Re: 2400 Mhz splitter
 

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

Re: 2400 Mhz splitter
 

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

Re: 2400 Mhz splitter
 

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

Re: 2400 Mhz splitter
 

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

Re: 2400 Mhz splitter
 

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)

Re: 2400 Mhz splitter
 

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

Re: 2400 Mhz splitter
 

We like Summer Glau methinks as you mentioned her:D

Re: 2400 Mhz splitter
 

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 ;)

Re: 2400 Mhz splitter
 

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?

Re: 2400 Mhz splitter
 

Yep, that's 10-base-2, also called "cheapernet" The "twist on" is a connector called a BNC.

There a variety that uses thicker co-ax called 10-base-5 or "thicknet", the cable didn't attach direct to the NIC though, it used drop cables from the network card to the main co-ax. These drop cables linked to the main cable with "vampire taps".

By the way, the impedence of the cabling and hence the value of terminators required was 50 ohms.

Re: 2400 Mhz splitter
 

Token ring now there's a blast from the past. It was the network Nynex used for all of its offices in the UK.

Re: 2400 Mhz splitter
 

Guys, does anybody knows where can i buy terminators for my splitter?

Re: 2400 Mhz splitter
 

Nope, but personally I'd make them myself, all the info has already been posted in this thread :)

Re: 2400 Mhz splitter
 

bnc connectors

Re: 2400 Mhz splitter
 

Is it really? I only saw a picture of the connector. What parts are needed to make that connector up then?

Re: 2400 Mhz splitter
 

An F male and a 75R

Re: 2400 Mhz splitter
 

If you see an open cab, there's usually a couple left on top of the tap plate. Then, if it's not to much trouble, could you please ring 151 and report the cab has open.

Everyone's a winner.

Re: 2400 Mhz splitter
 

They are available on ebay:- http://shop.ebay.co.uk/?_from=R40&_n...ohm+terminator

As mentioned earlier, a 4 port splitter will attenuate the signal more than a 2 port splitter. If you intend to only use 2 ports anyway, why not buy a 2 port one. You will find them on eBay, or Maplin sell them for £4.99. (code QQ69A)
