Long-distance Wiring: 2-stage Repeater Unit Connection

Stage 2

CS1W-RPT01

Repeater Unit

Not more than 2 Repeater Units (2 stages) must be passed for any node to reach any other node

Partial Optical Conversion: 2-stage Repeater Unit Connection

Stage 1

Stage 2		CS1W-RPT02 or
Stage 2		CS1W-RPT03
		CS1W-RPT03
		Repeater Unit

Two Wire-to-Optical Repeater Units make up a single set counted as a single stage. Therefore, not more than 4 Repeater Units (2 stages) must be passed for any node to reach any other node.

Examples of Incorrect Repeater Unit Connections
