FTE  (full-time equivalent) is an indicator used in human resources management. This indicator is used to convert the headcount into full-time positions. Each full-time position is assigned the value of 1.0 FTE . Let us assume that a company employs 100 part-time employees at 50 percent of the collectively agreed/standard weekly work hours. Each of these positions is scored as 0.5 FTEs. The indicator would therefore give us a result of 50 FTEs.

Available gas or water pipes can be used, eliminating the need for expensive underground construction works. Data transmission within the building itself continues to be conducted to the customer's apartment via the available copper lines or VDSL  technology.

FTTC (fiber to the cabinet)

Fiber-to-the-Cabinet (FTTC) means that a fiber-optic line is installed up to a point close to the subscriber. For the last section up to the subscriber drop, the signal is transferred to copper cable.

FTTH (fiber to the home)

FTTH describes the installation of fiber-optic cables up into a subscriber’s home. With FTTH, Internet speeds in both directions of up to 50 Mbit/s can be achieved. The customer can simultaneously receive several HDTV programs as well as use the Internet and several phone lines.
