Cleaning the Optical Connector

The design of the SG 2000 optical module connector enables you to clean it easily without removing the module from the node.

To clean the connector:

1If necessary, disconnect the service cable from the modules’ optical-connector assembly. Place a dust cover on the service cable connector.

2Lift the metal tab to release the optical-connector assembly and pull it out of the module.

CAUTION!

Do not pull the optical connector out more than two inches from the casting wall. If you pull the connector out too far, you must disassemble the module and respool the fiber.

3Remove the bulkhead adapter from the internal optical connector.

4Carefully clean the optical connector and bulkhead adapter using a suitable optical connector cleaning kit. If an optical connector cleaning kit is not available, clean the connector using pure isopropyl alcohol (99%) and a lint-free wipe. Dry it with filtered compressed air. You can also clean the bulkhead adapter using filtered compressed air.

5Re-assemble the bulkhead adapter to the internal optical connector. Ensure that you install the internal optical connector in the end of the bulkhead adapter bearing the metal tangs.

6Snap the optical connector assembly back into the module.

7If necessary, clean and reconnect the service cable.

SG2 - LR Optical Receiver

The SG2-LR is a line of forward-path optical receivers used in the SG 2000 node platform. It is designed to be used in conjunction with an AM-Blazer, AM-OMNI-LM*, MegaStar, or other similar optical transmitter.

Figure 5-13 illustrates the SG2-LR:
