Fibre-optic (ST plug)
The fibre-optic connections for
port 1 and port 2
(Figure 7) are provided with cover caps to
prevent the ingress of dirt into the ports. They are always to be mounted if no fibre-optic
connection is used. The caps can be removed after having turned them 90° to the left.

Fibre-optic connector type:
ST plug
Applicable fibre type: Multimode
fibre
62.5/125 µm (recommended) or 50/125 µm
Wave length:

Note
: Laser class 1 according to EN 60825-1 and EN 60825-2 is ensured with
fibre type

62.5/125 µm.
The fibre-optic connection for
port 3
(Figure 8) is provided with a cover cap to prevent the
ingress of dirt into the port. It is always to be mounted if no fibre-optic connection is used.

Fibre-optic LC links for the transmission and reception directions or bidirectional
The LC-connector necessary here is a connector type that represents a new generation of
connection technology, and is one of Small-Form-Factor-Connectors (SFP). The snap
locking allows for easy and safe operation (Figure 9). It is impossible to mix up the
transmission and reception with a suitable prefabricated FO cable.
