2.2.9 Other FO connectors<br />
For fiber optic connection in existing plants in many cases a connector BFOC/2,5 is<br />
still in use. The connector is also know under the trade mark "ST ® -Connector". This<br />
connector has been in use as industrial grade connector <strong>for</strong> many years <strong>and</strong> is<br />
available <strong>for</strong> all <strong>PROFINET</strong> fiber types (plastic as well as glass)<br />
Figure 10: BFOC (ST) Connector<br />
The ST connector is a single wire connector with bayonet latch. As both fibers of a<br />
connection are connected individually, special attention has to be taken <strong>for</strong> the<br />
correct assignment of sending <strong>and</strong> receiving fiber.<br />
The mounting of the connector is comparable to the mounting of the SC-RJ<br />
connector.<br />
