So this basically acts as a bridge between two cables.
Yes, it's no different than using a short RJ12 or RJ45 cable - but was originally wired in series. I changed it this way to use a modem there originally, but room usage changed so the modem moved to the far socket
Does it matter where in the wiring you install it? (right after the modem, in the middle, etc.) might try with my ADSL though the speed is astronomically lower and it's running on phone wiring.
If it's worth something the wiring doesn't share conduits with anything else.
This is VDSL2 - it's got tighter requirements
The simplest version is: The less wire the better, even if its unused. Any Y or T branches with the wiring will absolutely hamper speeds, as well as any untwisted wiring (ADSL Is more tolerant there, as long as the pairs arent seperated - if they un-twist and go apart like in the old 600 series connectors, that can hamper speeds)
And hell just the inside of the wall sockets can be garbage
This is my brothers antique he's too scared to touch, the coward (VDSL has no dangerous live voltage - it's safe to touch. ADSL can have 50V, so be more careful about shorts
On VDSL, the blue and white wire should go into the socket no more than the length of that white arrow - and straight into the cable from there. The dance his wiring does running around is to an extra socket that never even got installed, and causes a LOT of CRC and FEC errors on his line
This is what mine looked like after a 'professional' had done the job to the minimum standards in a rush
The gel caps were loose, uneven lengths, and both caps had untwisted ends
Using the unused wires to hold it together is perfectly acceptable, but doing this is not
5Mb higher sync and speed doesnt change by time of day now
This is the opposite side of the wall the choke is installed, so it's preventing outside interference entering the internal wiring from this point
The internal socket got damaged a few years back by my dad being an idiot - ironically this person had at least tried to install it correctly, but had lost or forgotten the clear plastic cap to ACTUALLY HOLD THE WIRES IN THE DAMN CONNECTOR
You'll notice the lenghts are different yet again - fixing this obviously went from 0 internet to working,but getting those blue and white wires the same length took the speed up 5-10Mb at the time
Even 2mm of untwisted wire at the end there can slow VDSL speeds, ADSL is more tolerant but you definitely want solid connections of even length, with as little untwisted wire as possible
VDSL uses frequencies that some FM radio devices can send signals out, same as faulty AC appliances (~17Mhz)
Any Y or T forks of unused wire act as an FM radio transmitter and receiver, so your VDSL signal leaks out the wiring to the outside, gets picked up by the excess as static out of sync with the main signal, and you lose chunks of the available frequencies - so disconnecting extra sockets entirely is the only viable solution there (and as i did, using RJ45 jacks lets you simply extend to whatever socket you wish on the fly)
When i first moved in we barely got 50Mb, now we're getting 82Mb as i've learned a few tricks and bought the right tools. A new wallplate with a Cat6 jack and punchdown tool is only $20Au here, so it's an incredibly affordable thing to fix up (If its legal where you are, and safe - again, some older phone systems ran upto 50v when someone calls your number so it's best to play it safe if you dont know)
