Have you ever known an engineer with equipment in-hand to not do otherwise? Of course I did (with the Verizon techs during the original install). Be very afraid. :p The saga continues: »10 way splitter

GeekGirl1, Yes +18 dbmv is the Tellabs 612 Video Output Spec, but why am I afraid that you also tested it yourself to confirm that it was true??:p

+18 dBmV

geekgirl,
you're confusing the cable company return path. they use freq's under 55 or so for their return. and the stb's don't talk back to the ont, they communicate back to the router via moca (over 1GHz). from their the return is sent on the data upstream path either by ethernet or coax. the fios return path is via moca which is above 1GHz

Not sure where that idea might come from but even if the splitter were perfect, you'd lose 3 dB per each 2x split - it's just the way things work. In practicality, the loss is more like 3.5 dB for each split for a high quality, passive splitter.

Split 2x = 3.5 dB, each leg
Split 3x = 1x3.5 dB, 2x7 dB (usually)
Split 4x = 7-8 dB, each leg
Split 8x = 14-16 dB, each leg

There can be other splitter configurations that would yield slightly different numbers like 5-6 dB per leg on a 3-way or ~11-12 dB per leg on a 6-way.

The 6-way splitter they used on my install is marked 11.5 dB per leg.

I would still look for the best splitter I could find. A standard splitter loses about 3db per tap so look for one that is only 2db down per tap which is what Verizon used in my setup.

said by GeekGirl1 :

Don't forget about the low-end frequency. You need to go down to 5 MHz. Some only go down to 40 MHz- not good enough and you'll have problems with the STB talking back to the ONT, like for VOD, guide, or widget info. The DCT700 doesn't use those features and doesn't care, the HD STB does.

said by Rattler :

Any splitter used should be rated for frequencies above 1 GHz otherwise you may have problems.

Your kind of asking for trouble if your going to finish off that ceiling and no longer have access to that splitter. You might want to think about installing an access panel there or re-run your coax wires while the walls or ceilings are open and homerun them to somewhere else that is accessible. I've been to homes where they have paneled over where their phone lines terminate or coax cables and the customer is stuck with opening the ceilings to isolate a problem.
