SIMPLE METER - Active Equipment Measurement
Active equipment should be monitored periodically to test its power levels and stability. The FiberMeter can
be directly attached to this equipment via a patch cord to check whether the transmitter is stable and within the
manufacturer’s specified power range.
NOTE: maximum transmitter output power exceeding the high end of the FiberMeter measurement range
could damage the photodector in the FiberMeter. If this is the case, a fiber optic attenuator will be necessary
to attenuate the signal sufficiently. Consult the manufacturer’s specification sheet for more information.
Use the following steps to measure the optical power of active equipment in SIMPLE METER:
1) Power on the FiberMeter and select SIMPLE METER.
2) Power on the active equipment to be tested.
3) Set the FiberMeter to match the output wavelength of the active equipment, and ensure that the
FiberMeter is set to dBm mode.
4) Connect the FiberMeter to the active equipment with a patch cord of the appropriate type.
5) Consult the active equipment manufacturer’s specifications to determine the correct power level of
the transmitter, and compare this number to the displayed optical power.
SIMPLE METER - Fiber Length Measurement
NOTE: THIS FUNCTION IS ONLY AVAILABLE FOR MODEL FO602.
The FiberMeter uses a loop-back method to measure the length of a fiber link. Use the following steps to
perform the length test:
1) Power ON the FiberMeter, and select SIMPLE METER.
2) Press to enter the MAIN MENU.
3) Select TEST FIBER LENGTH by pressing .
4) At the SELECT TEST TYPE menu, choose the menu option that best
matches the configuration of the fiber under test.
INSTALLED LINK - measures the end-to-end length of an installed fiber
cable, which is useful for calculation of loss budgets that are based on length (requires two fibers)
SPOOL OR JUMPER - measures the length of a spool of fiber or a test jumper
ABORT TEST - returns the user to the previous menu
