Just a quick note -- TME are offering low smoke jacketed installation grade cable in 8 strands G.652 SMF at 0,80 € per meter in 100m lengths -- so, it is basically the same as Cat 6. The price difference is that a splicer costs more than a LSA-Plus tool  :-DD

and you need equipment both ends also.

Settlement tomorrow!
Although it's unlikely I can do anything this week with it as I'm busy with other personal stuff.

I might have time for a walkthrough video today if I get the keys.
The exchange is happening at 12:30pm today and probably involves two trenchcoat wearing solcictors exchanging keys and bags of cash in a dark underground carpark.
They'll call me when it's done.

Now with two storge units and an office, I think I might change the locks to a single key for convenience.

Ha. If experience has taught me anything it will be a couple of secretaries doing the actual conveyancing.

Nice.   :-+

In regards to that big board, If permissible I would dynabolt a 90 x 45 horizontal pine stud to the wall then fix a few hinges and add a couple of hinged legs, this could act as a foldup assembly or packing bench if required. Also, if you are going to keep stock in that store room check whether it will be covered under your insurance policy. If you are running cabling for the network also consider whether you need to run some additional security cabling as well.

Re internet - just turn up with a  high-vis, hard-hat and a roll of cable - nobody's gonna notice another wire in the ducting.
Is the power metered seperately? If not, you did say it was next to your parking space - free charging!

^ He's right, you know.

The only way to upset the apple cart is to park in somebody's God given car spot.

Not metered, same as my bunker.

Actually not right next to my parking spot, it's quite a few spots over, not something you could string up an extension cord to unfortunately. As Ed said though, parking spots are god given.
There are a few power points scattered around the carpark.
There is actually no cable trough running to the storage unit, power and lights are through the concrete slab roof. So any comms cable will have to be run either in a new conduit or maybe along the top of the air ducting that conveniently comes from the MDF room.

Yeah but who'd notice another cable clipped to the wall...

All those who know I drive an EV. I wouldn't get away with installing a 20m extension cord across the roof.

I dunno man. With the right amount of vans with orange flashing lights. Some strategiclty placed witches hats. For good measure, have a dude with a clipboard and a high vis vest that reads C*v*d Inspector.

Now's your chance to develop wireless power charging and show those scammers how it should be done.

I'd imagine there would be plenty of spare pairs in those multicore phone cables running down to the MDF room

Pneumatics. No-one else is using that air vent so you could stick a speaker at one end and microphone at the other and play modem warbling sounds. Bandwidth not so hot, but think of the YouTube videos you could do!

I only have 12 or so spare pairs in my lab.

So if they come out in the MDF room, that saves the hardest part of the cable run, through those full-up floor holes.

As suggested before, have a look at fiber optical connections. It's more affordable than you think.
You could for example use 2x media converter (RJ45<->SFP Cage) + 2x SFP(+) module, + fiber cable.

The distance is not a problem and the fiber cable (it's usually a twin cable with TX+RX fiber) is very thin (usually +/- 2mm sleeve per fiber) and quite flexible, but it's also a bit fragile (bend radius, thin sleeve, etc.), so you might want to put it in a PVC pipe or tube for additional protection.

You can find fiber twin-cable even on large spools for extra long length, but attaching LC connectors your self is complicated (LC connectors are the most common type of fiber connectors for home & garden use :)) so it's better to use a prefab cable.

Common combinations:
For short range (max range <550m, but also limited by module RX sensor sensitivity and TX output power) you can use multi-mode (850nm) SFP(+) modules with OM3 or OM4 fiber with LC connectors.
For long range you can use single-mode SFP(+) modules (usually 1310nm) and OS2 fiber with LC connectors.

You can find very affordable SFP's in the 100M-10G range.

Example:
2x 1G TP link media converter + 2x FS.com 1G SFP module of choice (for example 1000BASE-SX) + OM4 fiber twin cable with LC connectors (TX+RX)

With the fiber cable in place you can always upgrade to higher speeds by replacing the media converters and SFP modules (as long as it has LC connectors and is suitable for the fiber you used).

In any case this kind of solution will be more reliable and will have a faster connection than any kind of wireless connection (especially in a building full of metal) and it's easier to handle than RJ45 network cable (with a prefab cable, in your situation).

Inspection of the cable run.



So approximately 15m to that cupboard. About 3.4m per floor (200mm per block x 17), or 16m down to the correct floor. I reckon about 25m to the 90 degree on the duct, maybe another 10m from there to the bunker wall. Your 70m guess isn't too far off the mark. I'd guess 80m for a real cable run. Copper should be fine, although I doubt they'll want to just run it on top of the duct - but that route will probably be fine to follow.

I would still run fibre, but that's me. Also, as to the 'box on both ends' argument - you may as well have wifi down in the bunker, so no extra box needed down there (APs with SFP slots for fibre are readily available).
