Introduction

Intent

This procedure provides guidelines for acceptable optical fiber endface appearance and defines the techniques that are commonly employed to obtain such appearance. This procedure is intended to promote uniformity in fiber end preparation quality for testing purposes only and does not address issues associated with endface preparation and examination for the purposes of permanent termination (i.e., connectorization and splicing). This FOTP is not intended to require examination of every fiber end, nor is it intended to establish firm requirements, and is made available only to provide guidelines for various levels of end quality that may be called out in other FOTPs. Lastly, the intent of this method shall not be confused with the intent of FOTP-179, which is concerned primarily with the comparison of relative results.

Hazards

The procedure may involve the use of certain hazardous materials, operations and equipment. It is the responsibility of whoever uses this procedure to establish appropriate safety practices and to determine the applicability of regulatory limitations prior to use. Note, in particular, that some fluids used may be flammable or may constitute health hazards, or both. Use proper precautions during handling and during the balance of the procedure. Constant, prolonged or excess exposure to solvents such as Freon®, 1-1-1 trichloroethane, methylene chloride and methyl isobutyl ketone may act as a carcinogen or damage internal organs. Use solvents in a well-ventilated area and avoid skin contact as a standard precaution. Consult safety data sheets for these materials.
