TIA TIA-455-8: FOTP-8 Measurement of Splice or Connector Loss and Reflectance Using an OTDR
SDO: TIA: Telecommunications Industry Association
DOD Adopted ANSI Approved Approved
This procedure describes the use of an optical time-domain reflectometer (OTDR) to indirectly measure the loss and reflectance of a splice or connector.
Loss or reflectance measurements may be obtained also by using FOTP-34 or FOTP-107. The latter values will be accepted as correct in the event of a dispute.
Some OTDR/fiber combinations appear to give "noisy" traces that may be repeatable for a given OTDR but not against other OTDRs with the same fiber. These appear to be related to polarization and coherence effects, and are being studied in FO-6.6. Some OTDR manufacturers offer noise filters, internal or external to the OTDR, and care shall be taken that these do not mask "true" artifacts of the trace. Moreover, parts of the trace that are noisy due to low signal-to-noise ratio shall not be used.
