Application Note 4 Reliable Operation of LSProbe 1.2 Field Probes
5 Replacing Sacrificial Cables
If a burn-in defect is observed at an E2000 connector, the complete sacrificial cable kit must
be replaced. A step-by-step description of the recommended procedure is given below:
1. Preparare replacement
a) Disconnect the complete sacrificial cable kit including its E2000 coupler and dis-
pose of it to prevent mix-up of cables or couplers.
b) Unpack a spare sacrificial cable kit. Skip step 2 for originally packed cables sup-
plied by LUMILOOP.
2. Clean E2000 connectors
a) Unplug both E2000 connectors from the E2000 coupler.
b) Clean the connector pair of the first E2000 connector as described in Sec-
tion 4 (Fig. 8) and plug it into the E2000 coupler.
c) Clean and connect the second E2000 connector.
3. Clean first end of sacrificial cable kit
a) Disconnect
both
FC connectors from the coupler.
b) Clean the first FC connector and connect it to the coupler.
c) Clean the second FC connector and connect it to the coupler.
d) Repeat steps a) through c) for the ST connectors.
4. Repeat step three for the second end of the sacrificial cable kit.
5. Consider ordering a new spare sacrificial cable kit.
Fixing burned-in FC/ST connectors:
In case of a burn-in defect at a ST or FC connector
due to improper handling, replacement is required. There are three destinct cases:
• In case of a burn-in defect at a fiber extension cable, the sacrificial cable kit and the
extension cable can be replaced with spares. Please contact LUMILOOP for support.
• In case of a burn-in defect at the Computer Interface, experienced users may remove
and replace the short orange fiber cable attached to the Computer Interface shown
in Fig. 9. Please contact LUMILOOP for detailed instructions. Computer Interfaces
without this short cable and associated cover can be refitted for improved system
reliability. For older systems the sacrificial cable is attached directly to the Computer
Interface. Please contact LUMILOOP support for more information.
• In case of a burn-in defect at the Field Probe, the system needs to be sent-in for repair.
Please contact LUMILOOP for support.
