A football ground: two offices, the covered stand and the scoreboard, joined by fibre.
The carrier's line reached one corner of the ground. From there we built three fibre sections: two at 10 Gb/s, joining the training offices to the administrative office and to the covered stand, and a third that carries the audiovisual signal to the scoreboard. Two of them cross by air, hung from the floodlight towers.
Five points, with photos of each. Select one here or on the drawing.

Where the carrier's line lands: its distribution cabinet. From here one fibre goes into the first rack.
A wall cabinet inside the training offices. The carrier's line arrives here and two sections leave, both at 10 Gb/s: one to the administrative office, one by air to the covered stand.

Arriving under the roof of the covered standThe administrative office. The section from Rack 1 links it to the training offices at 10 Gb/s and ends here in a small termination box.

Inside the finished officeThe covered stand. The 10 Gb/s section from Rack 1 comes in by air from the south-west tower and ends in a termination box with LC connectors; the audiovisual fibre to the scoreboard leaves from here.

The roof structure the cable follows
Along the wall of the cabinsBy air from the stand to the south-east tower and on to the north-east tower. From there it runs along the edge of the terrace, climbs a leg of the scoreboard frame and is fusion-spliced into a termination box. This fibre is not an internet connection: it carries the audiovisual signal between the stand and the scoreboard.

All three sections use 4-core fibre cable: two cores active, one to transmit and one to receive, and two kept as backup.

What the links are made of.
Four fibres in every cable. One pair carries the link; the second is already laid, ready to take over.
The switching that lights the fibre: 10 Gb/s between the buildings.
