1 m
Photodiode 40 µm - 80 µm, PIN InGaAs
Maximum distance 6000 meters or 9999 feet
Distance accuracy
(0 m to 3000 m or
0 ft to 9999 ft)
± 1 m for reflective incidents, ± 0.1% of
length
6
± 3 m for non-reflective incidents,
± 0.1% of length
7
Testing speed < 6 seconds typical
8
Connector Removable/cleanable SC adapter, UPC
polish
Fiber types tested 9/125 µm singlemode
Reflectance threshold
9
-40 dB typical
APC open detection
10
-65 dB reflectance typical and
backscatter > 3 dB above the noise
floor
5. With a reflectance range from -40 dB to -14 dB.
6. ± user-configurable Index of Refraction (IOR) error ± the incident
location error. Incident location error for reflective incidents: ±1 m from
1 m to 3 km.
7. ± user-configurable Index of Refraction (IOR) error ± the incident
location error. Incident location error for non-reflective incidents: ±2 m
for lengths
≤
15 m, otherwise ±1 m.
8. Does not include the active fiber test.
9. Finds and gives the location of an event that has a reflectance larger
than -40 dB, such as a dirty UPC connector.
10. Fiber length test with an open connector end that has a reflectance of -
65 dB typical (APC). Usually appears as a “non-reflective” event that falls
into the noise floor.
