Thanks for all the replies.
To hopefully reply to all;
I have the newer type of modem - I know the older style large modem/routers they used to supply as shown in that link, but they now supply a small white modem and two mesh wifi nodes.
I have repeatedly emailed gigaclear to ask if they could supply the cable, but have received two emails in about 4 months from them. Literally the worst customer service I have ever encountered; hence looking to source something myself.
I've also tried a number of suppliers, most of which didn't reply, one couldn't help, and the other has been very helpful and hopefully will be able to supply what I need.
I can post pics if somebody can explain how to do so - do I need to upload somewhere and post the links here? It looks the same as in the link shared, though, and is an SC connector as suggested.
