± (1 m + 0.1 % x length) for reflective incidents
1
± (3 m + 0.1 % x length) for non-reflective 
incidents

Testing speed
< 6 seconds typical
Connector
Removable/cleanable SC adapter, UPC polish
Fiber types tested

Detection of 
reflective incidents
3
-35 dB default threshold (User selectable: -20 dB to 
-45 dB in 5 dB increments)
Reflectance 
accuracy

± 4 dB
Maximum reflectance 
measurement
-20 dB
Detection of loss 
incidents
5
0.70 dB default threshold (user-configurable from 
0.5 dB to 6.1 dB in 0.2 dB increments)
Bulkhead quality
If no fiber is attached or if the connector is dirty, 
the troubleshooter displays 0 m or 0 ft.
Live fiber detection
Detects optical signals from 600 nm to 1050 nm 
and shows ACTIVE LINE if a signal is there. Looks 
for a signal every 3 seconds after the first detec-
tion. +7 dB maximum input power.
Certifications and 
compliance
P Conforms to relevant European Union directives
; Conforms to relevant Australian standards
$ Listed by the Canadian Standards Association 
CSA C22.2 No. 61010.1.04
 Conforms to FCC Rules, Part A, Class A
1. ± user-configurable Index of Refraction (IOR) error ± the incident location error. Incident location error for reflective incidents: ±1 m from 1 m to 1.5 km.
2. ± 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.
3. Finds and gives the location of an incident that has a reflectance larger than -55 dB. Detects incidents >1m after the bulkhead connector when the
 bulkhead reflectance is <35 dB. Detects incidents >3 m after an incident when the incident reflectance is <35 dB.
4. With a backscatter coefficient of -63 dB at 850 nm using a calibrated -14 dB reference.
5. Detects incidents >10 m after the bulkhead connector or any prior incident when the bulkhead reflectance is <-35 dB and the reflectance of any prior
 incident is <-35 dB. The maximum link loss prior to the incident is <7 dB.
