6 Fiber Handling Recommendations
Observing the handling recommendations stated below will ensure the continuous, reliable
operation of the LSProbe 1.2 Field Probe System. The recommendations should be brought
to the attention of all staff operating the system. In general, always handle fiber-optic sys-
tems with care.
• Avoid bending of fiber optic cables more than the criticial radius. For the fiber-optic
cables supplied with the LSProbe 1.2 Field Probe, the critical bending radius can be
given with 60 mm for short term and 100 mm long term bending.
• Avoid tensile strain on fiber-optic cables. Fiber-optic cables shall not carry the weight
of the connectors.
• Always use two sacrificial cable kits – one between Computer Interface and extension
cable and one between extension cable and Field Probe.
• Always disconnect the optical fiber connection using the E2000 connectors of the
sacrificial cable kits.
• Do not open any FC/ST fiber connectors unless absolutely necessary.
• Cover all open fiber-optic connectors using the supplied dust caps.
• Before connecting any FC/ST connectors, e.g., when replacing a sacrificial cable kit,
clean all connectors as described in Section 4. Use a fiber microscope to ensure that
the connector end-faces are immaculate.
• When a sacrificial cable kit has burned-in at the E2000 coupler, replace the complete
sacrificial cable kit including the E2000 coupler and clean all FC/ST connectors as
described in Section 4.
