Sure but I can fit quite a lot of fiber in very little space. eg an 864 is approx 1” dia.

Working with that much fiber is expensive. Too much work at each splice point. Huge inflexible cables. Expensive machinery to blow the fiber.

Compare that to blowing a 24f cable of 4 mm into a 6 mm id and 10 mmu od duct. You can carry 24 times 128 users on that. Much more than the 25 mm monster cable running p2p.

On top of that the multiduct has 12 of the smaller 10 mm subducts. You can blow additional cables as needed.

Granted I have only worked with outside plant delivering FTTH. But I don't see why not for a campus.

Baldur
