accomplished by using a family of

The various media types supported along with the corresponding IEEE 802.3 and
802.3u standards and connector types are as follows:

3.2.1Connecting Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using a 4PM with ST
1.Before connecting the fiber optic cable, remove the protective dust caps from the tips o the connectors on the 4PM. Save these dust caps for future use.
2.Wipe clean the ends of the dual connectors with a soft cloth or lint
Note: One strand of the duplex fiber optic cable is coded using color bands at regular intervals; you must use the
3.Connect the Transmit (TX) port (light colored post) on the 4PM to the Receive (RX) port of the remote device. Begin with the
4.Connect the Receive (RX) port (dark colored post on the PM) to the Transmit (TX) po of the remote device. Use the
5.The LINK LED on the front of the 4PM will illuminate when a proper connection has been established at both ends (and when power is ON in the unit). If LINK is not lit aft cable connection, the normal cause is improper cable polarity. Swap the fiber cables at the 4PM connector to remedy this situation.
