Table 11-2. Custom Limit Settings for OTDR Tests
Setting Description*
Length Enter a maximum length for the cabling.
Reflective Event Loss Enter a maximum value for connector loss. A typical value is 0.75 dB.
Non-reflective Event Loss Enter a maximum value for splice loss. A typical value is 0.3 dB.
Overall Loss Enter a maximum value for the loss of all components and fiber in the cabling. You
may also enter a minimum loss value if receiver saturation is an issue in the
installation.
Segment Attenuation Coeff Enter a maximum value of attenuation per kilometer for a fiber segment in the
cabling.
Note
The segment attenuation coefficient for shorter segments (50 m to 500 m,
depending on wavelength and fiber characteristics) may not be measurable.
Overall Attenuation Coeff Enter a maximum value of attenuation per kilometer for the entire length of the
cabling.
Event Reflectance Enter a maximum reflection value for a single event.
* Minimum values are usually not used, but are available for special situations.
