What is this Prysmian device on telegraph pole

[Turtletom]

Hi I have come home and at the bottom of my drive way have noticed this thing bolted about 7ft up the telegraph pole with a laser/laser radiation warning sticker on it.

Anyone know what this is and what it does or what all the numbers mean?

Can't see pictures?

And would that be Prysmian?

Let's see if this link works for the picture

But just in case it doesn't, it's a Prysmian optical fibre jointing system. I suspect the numbers are circuit/service identifiers and the laser radiation symbol is on there so as to make sure people don't open it without suitable eye protection.

Awseome thankyou, nothing to worry about then?

Yes this is it thankyou

Not unless you were thinking of cutting the fibre cable and looking down the end.

Looks like BT fibre is coming your way soon

telegraph poles in essex???? thought pigeons had made them obsolete down there.

Apparently they're expecting an influx of Scousers into Essex, so BT are removing all the copper and replacing with fibre.

bllooody spoilsports. have to search the midlands now.

Don't waste your time here, the Pikeys from Lincolnshire have had it all.

That fibre splice box should be a lot further up the pole than that.

BT were pulling the copper cable out round our way a few years ago, apparently BT was getting £3000 for a skip full.

BT copper pairs are horrible to work with, they're packed with grease. stuff gets everywhere...

For sure it's a fibre optic repeater / booster,
The radiation warning is for the laser diode.
But unless your looking down the fibre when it's on,
Then their is no problems.
But you have to account for all types of idiots !

Thanks guys, it is safe to say it is for fibre optics when i left this morning they are working up the road with a big spool of black cabling and under the paths.

I did think it was a bit low down but maybe it is temporary who knows

Hate to disagree, but I don't believe it's a repeater... reasoning... only two 'cables' entering (if it was a repeater I would expect to see a third - the power supply), plus there is no warning about the presence of potentially hazardous voltages you might expect if there was a power supply present in there. Plus I don't believe Prysmian make repeaters.

The laser radiation warning is required as if you bend a fibre beyond it's minimum bend radius there is a good chance the reflection fibres require to work will break down (the angle of incidence will be too great) allowing laser radiation to be emitted from the sides of the fibre, whilst not as potent as looking down the end of a fibre, it is still strong enough to cause permanent retinal damage.
