I am in the process of getting my house reinsulated. I currently have only 2 tvs, one in my living room and the other in my bedroom. I want to try and run the wiring for the additional 3 bedrooms before my crawl spaces are closed in due to the insulation. Here is my setup: The Fios box is installed on the back of my house and the wire comes out and runs down the length of the house to a splitter. At this splitter, one wire comes into the house via the back bedroom (no tv) and goes right to my modem and the other wire runs up the outside of the house to the second floor where it meets the second splitter and from there 2 wires come off that splitter into the attic and each wire goes to each tv. I have several questions regarding this situation:
1) On the wire that comes into the house and goes to my modem; can I place another splitter on that wire before it goes to the modem in order to get tv to the 2 bedrooms downstairs and the modem? If so what type of wire and splitter do I need? Anything else needed?
2) For the wire that runs up the outside of the house to the other splitter, I am pretty sure that it has only 2 outputs so I will have to swap it out for one with either 3 or 4 outputs. What type of cable and splitters do I need to run for the additional bedroom upstairs? Anything else needed?
Any help with this would be great.

For the cable - use tri or quad shield RG6 cabling,
and for the splitters, make sure you use 1000mhz rated splitters and above. Also if you have extra unused end, make sure to get terminators for those ends. Generally speaking the less splitters the better, because you'll get loss of signal with each splitter you introduce. It's usually only -3.5 dB anyway, but still, that can make a difference.
nothing else is needed unless you're crimping your own cables.

Do the splitters need to be bi-directional or does it not matter? Also, what type of terminators do I need? You also said the less splitters the better but could I add an amplifier in the mix with the wire that goes to my modem and the two bedrooms downstairs to eliminate signal loss?
Everything needs to be bi-directional ... rated for 1GHz or better ... and in general amplifiers are a bad idea particularly since many of the cheaper ones aren't bi-directional. Buyer beware. In a typical home installation, you really shouldn't need any amplifiers if you've got quality wiring.
The best wiring design is to home run each connection point to a central location and wire out from there -- a single high quality multi-port splitter then being employed. Absent that capability, keeping the number of splitters to a minimum between the ONT and each device and between each device and the router is the objective. Most 2 output splitters give you a -3.5db signal loss, a 3 output splitter gives you -3.5db on the first output and -7.0db on the second and third, a four output gives you -7.0db loss on all outputs. With that said ... my highest splitter count between ONT and device is 4 (5 to the router) with one leg on older coax ... and everything works fine. My biggest problem initially was the lack of a terminator on a splitter which seemed to allow a lot of noise into the system and kept some of the channels running on higher QAM frequencies from coming in.
Something like this will do for terminators ....

Amplifiers are a no-no unless they are designed for a MoCA system. The average amp (Radio Shack or the like) have a return path below 50 MHz which the cable companies use. The MoCA (IP over coax) signal is >900 MHz and the typical amp will block the return signals (upstream - your communication to the FiOS network).
As was said, unless you have horrendously long runs (> 100 feet) or more than 8 taps you shouldn't need an amp.
I apologize for my ignorance but what do you mean by, "The best wiring design is to home run each connection point to a central location and wire out from there -- a single high quality multi-port splitter then being employed." Also when you stated, "my highest splitter count between ONT and device is 4 (5 to the router) with one leg on older coax ... and everything works fine" does that mean you have 5 separate lines coming from one splitter or you have 5 different splitters?
On the first comment ... I mean that I'd have an individual piece of coax running directly from that location to a single location somewhere in the house (usually near the ONT) so there are no splitters along the way from the ONT to the TV except for the one you need right next to the ONT to split out the coax for all the various connections. As my house is already wired, I don't have that flexibility thus the second comment.
On the second comment ... I mean that if you start at the back on a STB and were able to go from that location to the other location WITHOUT letting go of the cable you would encounter the indicated number of splitters along the way.
In general, high quality coax and as few splitters as possible (splitters rated for 1GHz or higher with no filtering) and no amplifiers is the configuration you want.
In my situation above, the issue seemed to be caused by the 5/2400Mhz splitters with DC passthrough. Why would that be an issue if I am not sending DC back?
When I ran cable in my apartment, I really wish I had run home runs from where the input was. However, FiOS wasn't around then (even then I would have had it all backwards, as the ONT is in a bedroom closet). Instead, I have 3 splitters in my configuration, which is concerning.
Will either of these splitters work for what I am tryoing to do:

they are both high bandwidth splitters so both should work fine with Verizon
