3 NAMES AND FUNCTIONS OF EACH PART AND CABLING
3-3
3.2 Cabling
(1) Primary ring (PR) cabling
As shown in Figure 3-2, connect the TX and RX receptacles of two adjacent OD.RING
modules with optical fiber cables to configure the primary ring. Communication data flows
from TX to RX in the direction of the arrow.
(2) Secondary ring (SR) cabling
In secondary ring cabling, connect the TX and RX receptacles of two adjacent OD.RING
modules with optical cables as in primary ring cabling. In this cabling, however, be sure to
connect TX and RX so that communication data flows from RX to TX (i.e., in the direction of
the arrow which is the reverse of the direction of the primary ring).
Figure 3-2 Optical Fiber Cable Connection
CAUTION
Be sure to assign ID numbers to optical fiber cables for identification because
cabling errors tend to occur easily.
Optical fiber cable cannot be used to connect an LQE010 module and an
LQE015 module together. Be sure to connect only LQE010 modules or
LQE015 modules using such cable.
