UPC Connect Box - straight to 14db amplifier/splitter in basement?

Hi all,

 

I am about to move my infrastructure (Ubiquity, NAS, UPS..) down into the basement including UPC Connect Box. I do not have a "traditional wall connector" in the basement where the UPC signal comes in. Instead the UPC signal goes into a 14db amplifier and then a 6 way splitter, with 2 free connectors (see attached picture). The splitter deliver 4 signals upstairs to 15db multi media wall mounts. All completely normal.

 

Question is: how "hot" a signal can the Connect Box handle?

Will the UPC Connect Box work plugged straight into the splitter, without attenuator inbetween?

Does anyone have a technical/hardware manual for the Connect Box?

 

Thanks in advance, Tim

Even though "support" had "never had a question like this" this appears to be what I need:

Duh!

Thanks Daniele.
"Facebook support" has ordered the above piece for me.
Once received I will update this thread.

...I turns out that "facebook support" cannot order this article.

@glarner can you help?

@Tim8805 , Please excuse me, but your request exceeds my knowledge. 

 

Furthermore we do not recommend to do anything on the installation yourself, because afterwards a technician of ours has to come by in case of a malfunction and refuses the support.

 

Is there an electrician company on your distribution box? If so, they can answer all your questions. Please call them, they did the installation and can give you the exact values.

Re: UPC Connect Box - straight to 14db amplifier/splitter in basement?

Hello @Tim8805 

 

The nominal Output Power (Downstream) of an 14 dB Amplifier is 82 dBµV @298 MHz and 84 dBµV @834 MHz (a positive slope to compensate the high attentuation of long cables)

A sixway Splitter has an decoupled (nominal) attentuation of 10 dB.

 

 

84 dBµV

- 10 dB (6-Splitter)

= 74dBµV on the Port

 

This is, even you thought,  to high power. The optimal level for the cable modem is between 58-66 dBµV.

An 11 dB Wall Outlet is perfect for star-topography.

 

74dBµV (Port)

- 11 dB (Outlet)

= 63 dBµV @834 MHz (61 dBµV on the lower frequency 298 MHz)

 

Never forget the terminator on a Splitter/Througput Port (Outlet).

 

Your Modem compare to EuroDocsis 3.0/3.1, this standard definate the power level for Downstream/Upstream.

Here is a Quick overview:

I hope, i has helped you (and all other customers in the cell)

Thanks Rene, much appreciated.

 

Do you agree that a 10 or 16 db attenuator straight onto the cable between splitter and modem would be equally good?

 

E.g. https://axing.com/en/produkt/bzu09110-en/

 

Thanks, Tim

@glarner 

 

P.S. interesting article about DOCSIS!

I had a look at my signal (attached, attached via 15db wanddose)

Is it a bit "hot" already? and will 10-11db damping be enough? (dose or cable attenuator)

 

Thanks, Tim
