Heck! My cover name has been exposed!

Cheers!

As if ... but then the initials are the same!

I've had FTTP provided by Community Fibre. The drop fibre is pretty thick - looks round. I think it has a Kevlar spine.


CF have been pretty tough with their fibre on runs between OR's DP/sub-DP - it's pulled completely tight - unlike the copper wires which aren't.


Is this because fibre doesn't suffer from thermal expansion?

If I’m honest, it wasn’t ADSL Max’s moniker I was after ...

there was another prolific poster, William Grimley or similar, who was forever ‘fishing’ with thread titles like “Whoah ! Did see that ?” Then inviting people to view the three FEC’s that had appeared on his router stats ......

... but since I still cannot recall his actual username, I went with Max’s instead, and got the hoped for response anyway.

Don't know teh answer to the question but glass does expand however it is way less than copper:

Glass 0.67x10^-6/K
Copper 17x10^-6/K

So a ratio of about 1:25

The fibre itself is quite fragile, it certainly should have no tension on it. However outside plant fibre cables are usually extremely well protective of their contents, often with so called 'loose tube' or gel filled tubes encasing protecting the strands of fibre. Where the fibre is blown its encased in a series of micro-ducts that form an airtight end to end superhighway that packages of fibre called 'bundles' are blown down. BT actually invented (and for a long time held the exclusive patent) for blown fibre.

I’m just happy he hasn’t drifted into ‘ADSL Max - like’ obsession.

Its coming up to 3 months since he last posted here, hope all is well with him.

Edit: You can all stop wondering, just seen him post the following on ISPreview "Sky can [censored] off for all I care"

I've got a feeling I saw a post on the main news page in the last month from him asking for his ban to be lifted.

Oh that explains it, I didn't know about the ban.

Here's the cover picture!

It's a pity that the wording on the plate is obscured.

Cheers!

Haha. I think the title of the thread there confirms any suspicions...despite the flattened gum on the lid of the box obscuring the ID and blushes of the owners.....😂
