OUTPUT PORT MAINTENANCE
The LSMM utilizes a physical fiber connection at the output port. This ensures a steady power level for performing
insertion loss tests.
Be aware that any test jumpers must be inspected and cleaned before plugging into the LSMM unit. If soiled or
damaged connectors are inserted, they can cause damage to the LSMM output port and the unit may need to
be repaired.
