Author Topic: Should This Junction Box And Drop Wire Be Replaced (With Pics)  (Read 3247 times)

So i went in to the loft today, and found the junction box for our property. I discovered that Fig 8 drop wire was in place as well as an old bakelite junction box. The Wire that goes from the pole to the house however is modern as it was replaced in 2007. Do you think what i've included in the pictures will impact VDSL speeds? How would i get it replaced?

To answer the question, yes, that figure of eight cable will be somewhat detrimental to any xDSL service. How detrimental would be hard to quantify. The lack of a twisted pair allows extraneous signal pick-up. However, left undisturbed, such cadmium copper coated steel wire conductors are really quite heavy duty and strong. (Far stronger than any modern day 0.4 mm wire cored cables!)

The junction box is a good example of the type that was fitted during the 1930s to 1950s. (Approximate dates.) All it is doing is connecting the incoming service feed to the CW1308 specification internal cable. Why replace it when it is doing a perfectly good job?

Sorry but I don't understand exactly what it is that you are suggesting.  ???

If it was within my reach and ability, it would discretely be replaced by a length of the appropriate grade external cable. Knowing how badly you are afflicted by Radio China International, after dusk and during the night, I would make the effort to ensure that the cable was replaced.  ;)

I think you might just be mis-understanding what is meant by fig 8 drop wire.

Older dropwire was a 2 core cable with a flat figure of 8 type profile rather than modern cable which is twisted pair within an outer sheath.

Thankyou very much and have reconfigured my modern twisted cable back to a figure of 8 no harm done to line just my pride  :-[
