2Insert the wavelength-specific CWDM GBICs into their respective network device(s). To install a CWDM GBIC, see Installing CWDM Gigabit Interface Converters, part number 212256-B.

3Clean all fiber optic connectors on the cabling (see “Handling and cleaning fiber optic equipment” on page 49 ).

4Connect the fiber optic cables from the CWDM GBIC transmit (TX) and receive (RX) connectors to the OADM Equipment RX and TX equipment connectors (Figure 16).

5Make the following network backbone connections (Figure 16):

•Connect the west network backbone fiber optic cable to the OADM west connector.

•Connect the east backbone fiber optic cable to the OADM east connector (Figure 16).
