FON, Fiber Optic Node

The FON unit is the heart of all Powerwave fiber optic repeater systems. The FON unit

contains an optical transmitter and an optical receiver. No other Powerwave repeater

building block has these facilities.

Figure 2-3. The FON unit

This unit is normally part of the FOU, Fiber Optic Unit.

The FON unit is detailed in Chapter 3, FON, Fiber Optic Node.

FOU, Fiber Optic Unit

The FOU, Fiber Optic Unit, is a complete unit for fiber optic interconnection of two or

more repeaters. It is built up on a flanged plate and can be inserted in all types of LGP

Allgon AR repeaters. In the simpliest configuration, it contains a FON board and a DPX

filter.

Figure 2-4. The FOU unit

Figure 2-4 shows an example of the FOU with a typical configuration. Both RF and

optical devices, such as DPX filters, RF combiners, optical splitters and WDMs, can be

configured on the FOU plate. The FON board is always included in the FOU.

The FOU is also described in the FOU, Fiber Optic Unit section in Chapter 4.
