In an FTTO environment, fibre is laid up vertically from the central distribution switch right to the office floor, where it runs horizontally to active FTTO switches at the users' workplaces. The final distance of 3–5 m to the end user desk is bridged using standard 8P8C twisted pair patch cords. There are only two network levels: the core and the access with no aggregation or distribution level in between compared to traditional

each) are not required and the room saved can be used alternatively. Another advantage of FTTO infrastructures is their flexibility. New users, services or applications can be easily accommodated into the network. Moreover, network adjustments, upgrades and physical changes are seamlessly integrated into the existing network without operation stops. Also, FTTO installations can be realised on average by 60% quicker than their traditional counterparts. Research shows that using

Among the more advanced features of FTTO switches are precise link diagnostics (on the uplinks and TP ports), programmable function contacts, hardened management against hacking attacks, intelligent power budget management, easy reboot with memory cards, and extended durability. Many products have a

In FTTO designs there is no need for floor distributors, and no investment in cooling, power supply and security equipment (i.e. access control, fire protection, sensors, UPS) for the floor distribution room is required. Floor distribution rooms hosting technical equipments (usually measuring 6–18 m

Fibre infrastructures need less cabling than traditional copper twisted pair networks. The volume of fibre optics cabling is considerably reduced. This is due to a very small fibre optic cable diameter of 9–50 mm. Typically, one FO-link replaces four twisted pair cables with no loss in

Since FTTO relies on
Ethernet transport, additional cabling may still be required for applications that could be transported over structured cabling, but not over an Ethernet network, e.g.
