26.3Connections

26.3.1 Introduction

This section gives an overview of typical system connections using the fiber interface:

•Connecting the POF cable (see section 26.3.2).

•Connecting the GOF cable (see section 26.3.2).

•Connecting an external power supply (see section 26.3.3).

26.3.2 Connecting POF and GOF cables

Fiber interfaces convert from POF to GOF to connect two pieces of equipment that are more than 50 m apart. Usually, they are used in pairs. The first converts from POF to GOF, whereas the second converts from GOF back to POF (see figure 26.3).

The GOF connector (see figure 26.4) is an SC connector, which uses invisible infra-red light (1300 nm).

26.3.3 Connecting a power supply

This unit is powered by the network controller, via the Praesideo system bus. But the fiber interface is delivered with a separate Kycon KPP4-P connector to connect an external power supply to the fiber interface. The Kycon KPP-4P connector has four pins (see figure 26.6):
