Cable Internet - Splitters and Amps

Post by CM Weaver »

Finally, cable is going to be available at my home in 4 weeks and I have a questions about splitters and amplifiers. If the cable coming into my home is not close to the actual install location of the modem, can I extend the cable with an amplifier and splitter? What's the general rule on this?

I work for the cable company and their policy is to give you a self install kit and only come out if there are problems (line noise, signal levels, etc.).

Just want to have my ducks in a row when I'm finally able to plug in and get off this damn dial-up! Thanks in advance!

The correct amplifiers are not recomended. The incorrect ones will cause lots of problems since they are meant for one way service.

From your drop, there should be 1 splitter between your drop and modem. Make it a high quality splitter. If you need more splits, do it off the other splitter leg with other splitters.

As long as you you good rg-6 cable from your drop, you should be able to go a ways.

Heh, no :) I'm a technician that monitors, supports and troubleshoots the systems that deliver that national out of band control and authorization stream for digital and analog cable. I'll go into more detail if you like.

I'm not a field guy and work on the video side of things.

I can hook up my cable no problem, I'm just anticipating any possible problems with the drop into my house not being close to the install point for the modem. I'm being proactive and since I've never had a cable internet I wanted to ask you guys about any nuances, limitiations, and do not's so I'm prepared. I've got got 3 other lines coming off my drop via splitters and amps for video and didn't know how that would play out with data.

The company just has a new policy for employee installs that it's to be done self install and only come out if problems beyond my control. I'm far from an idiot when it comes to technical stuff, but I'm also a proactive person, wanting all the details I can get for stuff I'm not familiar with.

I didnt mean to make it sound like I was saying your ignorant on the subject heheh, I was just curious because ive had to install several modems in fellow employee's homes because they arent in the field and dont really know anything about it.

You work in the head ends?

You should be just fine if you have a decent drop to your home, and try to stay off the 1st or 2nd splitter (its unlikely your on a 26 tap, at least not in most areas anymore as they have 23's and/or have upgraded the return to 20 instead of 24, giving you enough to split twice before you start to have problems).

No problem, wee, for a second I thought I was over on GenMay :)

No, not in the headends. I'm an AT&T Broadband transplant to Comcast with the merger last year. In the AT&T days of digital cable they managed headend devices, settops and the services we delivered to headends nationally.

Basically, a cable system contracts with Comcast to deliver programming and have us manage authorization of their headend devices here from Denver. We manage lots of small cable systems as well as large metro systems. Unfortunately, Comcast has a different view of national control and we are in the middle of converting all those systems to regional control.

I'd be happy to go into more detail in another thread :)
