No, the idea of total internal reflection is that it allows light to move around bends and curves in the cable. It will affect where the light lands on the sensor at the Optical Termination Point, but otherwise it would not have any detrimental effect.

@NEXUS2345,

would Openreach & BT Retail know if a cabinet had a faulty fiber connection?

The engineers who come to my house only handle the D side connection

OpenReach should be able to tell, and so should Wholesale. If there was damage to the fibre it would be losing data packets or not transmitting data at all. Optical fibres usually have 0 packet loss so it should flag up immediately.

@NEXUS2345,

how would the stats for a faulty fiber cable look like?

It would manifest as packet loss or total failure. It would also affect all connected to the DSLAM, not just you.

@NEXUS2345,

looking at my SNR graphs would you say my problem is definitely not an E side problem?

You are on VDSL, so the E side has nothing to do with the parameters such as SNRM or even sync and attainable. The only thing that affects VDSL is the D side.

Openreach aren't going to replace the cable for any1. If my VDSL continues to drop out I'll drop to ADSL, if it continues to disconnect then satellite

Nope, you're probably right going by my experience, but the idea was that you'd get a different pair along the entire length from cabinet to the house with a new master socket as your existing line would still be active until you cancelled it after the new line was up and running.

@Ronski,

I've already had a D-side swap half way to the cabinet, the remainder of the cable is supposedly high gauge so should be good,

I've had the line from the pole to my house completely replaced & I have an Openreach MK3 face plate so my line is as good as can be

The real fix is a fiber cabinet out to my house
