6.4.1. Optical Interface Connection
 Single Optical Fibre-module
Figure 6-13 shows that when using a pair of single optical fibre-modules, the wavelength of the two modules
should be different, for example, 1271nm & 1331nm. See Table 51 for the optical fibre module corresponding to each
port. 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. See Section 9 for how to resolve this issue.
