Follow these steps to clean the cable and connectors:
Step 1. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free isopropyl
alcohol pad from a fiber cleaning kit. See Figure 5.
Figure 5. Cleaning Fiber Optic Cables and Connectors
Step 2. Use canned air to blow out any dust from the female fiber coupler.
Follow these steps to connect the cables:
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
Step 1. Plug in the optical cables.
• If you have a simplex optical connector, use a bi-directional cable between a pair of L322s, one at
1310 nm wavelength and the other at 1550 nm wavelength.
• If you have a duplex connector, use Tx to Rx, and Rx to Tx orientation to avoid transmission
errors.
Caution: To protect the Ethernet port from an intrabuilding lightning surge, use a properly
grounded shielded cable.
Step 2. Plug the unshielded twisted pair (UTP) Ethernet cable with RJ-45 connector into the User
port on the front of the CLIM.
Step 3. Label each cable and connector with the signal name and direction.
Step 4. For cable connections to other modules in the chassis, see the appropriate user manual for
details.
2.3.2 Measuring Fiber Link Attenuation and Transmit Power
It is recommended to determine link attenuation and transmission power before starting normal link
traffic. The attenuation factor and transmission power identify potential problems with links near the
lower limit of receiver limitations.
For details on link attenuation, see Chapter 5. For details on transmission power, see Chapter 5.
