46 where C is the maximum allowable Connector Loss (in dB), L is the length of the run (in
47 kilometers) and F is the maximum allowable fiber loss (in dB/km). S is the total splice
48 loss (# of splices * max. attenuation per splice).
50 OTDR Testing
51 All fibers even those that are left unterminated (if applicable) shall be documented in one direction of
52 transmission using an Optical Time Domain Reflectometer (OTDR). Multi-mode fibers shall be tested at
53 850-nm (nominal). Single mode fibers (if applicable) shall be tested at 1300nm (nominal). The OTDR(s)
54 shall incorporate high-resolution optics optimized for viewing of short cable sections. Access jumpers of
55 adequate length to allow viewing of the entire length of the cable, including the connectors at the launch
56 and receive end, shall be used.
58 OTDR traces revealing a point discontinuity greater than 0.2-dB in a multi-mode fiber, or 0.1-dB in a
59 single mode fiber (if applicable) at any of the tested wavelengths or any discontinuity showing a reflection
60 at that point shall be a valid basis for rejection of that fiber by the Owner. The installation of that cable
61 shall be reviewed in an effort to remove any external stress that may be causing the fault. If such efforts do
62 not remove the fault, that cable and the associated terminations shall be replaced at the expense of the
