3.2Connecting Ethernet Media

The Multilink ML1200 Switches are specifically designed to support all standard Ethernet media types within a single Switch unit. This is accomplished by using a family of different Fiber Connectors which can be individually selected and configured per-slot. See Section 2.2 for a description of the PMs.

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

IEEE Standard	Media Type		Max. Distance	Fiber Connector
Fiber:
100BASE-FX	mm Fiber		2.0km (6,562 ft)	SC
	sm Fiber		18.0km (95K ft)	SC
100BASE-FX	mm Fiber	2.0km (6,562 ft)		ST
	sm Fiber		18.0km (95K ft)	ST
small form factor	mm Fiber		2.0km (6,562 ft)	MTRJ, MLC
small form factor	sm Fiber		15 km	SLC
Copper:
10BASE-T	twisted pair		100m (328 ft)	RJ-45
100BASE-TX	twisted pair		100m (328 ft)	RJ-45
1000BASE-TX	twisted pair	100m (328 ft)		RJ-45

mm = multi-mode, sm = single-mode

3.2.0.1 Connecting Fiber Optic ST-type, “twist-lock”

The following procedure applies to installations using a PM with ST-type fiber connectors.

This procedure applies to ports using a ML1200 module, MST-type port.

1.Before connecting the fiber optic cable, remove the protective dust caps from the tips of the connectors on the PM. Save these dust caps for future use.

2.Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue dampened in alcohol. Make certain the connectors are clean before connecting.

One strand of the duplex fiber optic cable is coded using color bands at regular intervals; you must use the color-coded strand on the associated ports at each end of the fiber optic segment.

3.Connect the Transmit (TX) port (light colored post) on the Multilink PM to the Receive (RX) port of the remote device. Begin with the color-coded strand of the cable for this first TX-to-RX connection.

4.Connect the Receive (RX) port (dark colored post on the PM) to the Transmit (TX) port of the remote device. Use the non-color coded fiber strand for this.

The LINK LED on the front of the PM 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 after cable connection, the normal cause is improper cable polarity. Swap the fiber cables at the PM connector to remedy this situation.
