The optical connector unit includes an optical module and optical fibre. Figure 6- 14 shows that when using a double
optical fibre-module, the optical transmitter and optical receiver should correspond to each other. In other words, the
optical transmitter of optical module A should correspond to the optical receiver of optical module B and the receiver of
A should correspond to the transmitter of B. The optical receiver and transmitter terminals of the optical module can be
determined by the triangular mark on the optical module. Figure 6- 14 shows the triangular mark in the yellow box and
the red and green lines indicate the optical fibre connections.

Each pair (2) of optical module cages has four LED indicator arrows. The two on the left are green and the two on
the right are red as shown in Figure 6- 15. The indicator arrows represent the synchronization status of the upper and
lower optical modules. When optical module A has synchronized with module B (both uplink and downlink), the
indicators turn green as shown in the right pair of indicators in Figure 6- 15. When the optical module is unplugged or
not synchronized, the indicators are red as shown in the left pair of indicators in Figure 6- 15. Check whether both
indicators turn green after connecting one pair of optical modules. If they are red, the terminal has not synchronized.
