![]() If you’re using WiFi, your router converts the Ethernet connection into a radio frequency that’s then broadcast to your wireless devices.Ī MoCA network uses coaxial cables-like the cords that screw into the back of your TV-to connect your modem to the internet. Though Ethernet can travel over coaxial cables, it’s common practice (and cheaper) to use twisted pair cables-the thinner cords that clip into your modem and computer-to connect to the local area network (LAN). Most households use Ethernet cables to connect to the internet. Gamers and streamers, this one's for you. You'll just need to find a sibling properly sized for your "OTA" top-level needs.MoCa is shorthand for Multimedia over Coax Alliance, a wired internet option that uses existing coaxial cables to connect to your network instead of traditional mesh WiFi. It's pretty straightforward and provides good insight on MoCA loss budgeting, preferred splitters, and the performance value of a "PoE" MoCA filter.Īs for "designed for MoCA" splitters, the following series are all cited as having lower output port isolation in the MoCA frequency range (though less critical in a single splitter setup with a "PoE" MoCA filter installed, as explained in the above presentation): I recommend reviewing this IEEE presentation covering "MoCA Basics" (PDF). but requiring a higher power level for the MoCA gear to adjust for the attenuation.) (The out-of-spec components also becomes more critical when using MoCA 2.5, since it wants to use almost the entire MoCA spectrum, shifting beyond the puny 50 MHz required for MoCA 1.1, but MoCA 2.5 can still power through and deliver full performance. It's just that the added attenuation of sub-optimal components can balloon in a more complex setup, pushing the node-to-node path attenuation over MoCA's allowed limit of 57 dB. That said, given your issues accessing the splitter, you can make the argument that oversizing the central splitter and connecting all lines that you may want to use in the future would make sense, decreasing the need to access the splitter location in the future.Ĭlick to expand.To be clear, MoCA can work over RG59 *and* through standard digital cable (1002 MHz) splitters. Ideally, the splitter would be right-sized to just the number of splits/outputs needed, to minimize signal loss (both OTA and MoCA), and any unused output ports would be capped with a 75-ohm terminator. Most splitters that size are either 6-way or 8-way (6 outputs or 8 outputs), so I'm wondering whether that's actually a 6-way/6-output splitter or an 8-way/8-output splitter with an unused output. Re: the diagram and the "7-way splitter". Amplifier shouldn't be necessary if one isn't currently required, though the attenuation/specs of the replacement splitter may be marginally more severe.Įdit: p.s.The 2-way splitter in the remote room(s) could be skipped if the chosen MoCA adapter has an RF pass-through port (to which the TV could be connected).A "PoE" MoCA filter is required on the input of the top-level "OTA" splitter.No "PoE" MoCA filter is needed on the Internet modem line.Diagram looks GOOD, with the caveats previously cited:
