I nternational Standard IEC 61 291 -2 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of I EC technical committee 86: Fibre optics This fourth edition cancels and replaces the third edition published in 201 This edition constitutes a technical revision This edition includes the following significant technical changes with respect to the previous edition: a) the title of this standard has been changed from digital applications to single channel applications; b) the scope has been changed and, as a result, the titles of tables have been changed; c) Terms and definitions have been revised; –4– I EC 61 291 -2: 201 © I EC 201 d) three tables regarding the minimum list of relevant parameters of power amplifiers, preamplifiers and line amplifiers based on semiconductor optical amplifier (SOA) components have been added; e) transient parameters have been added in the minimum list of relevant parameters of preamplifiers and line amplifiers based on optical fibre amplifier (OFA) module The text of this standard is based on the following documents: CDV Report on voti ng 86C/1 31 8/CDV 86C/1 365/RVC Full information on the voting for the approval

used in single channel applications I n the performance standards or product specifications, other specifications such as ratings, operating conditions, tests and pass/fail criteria could be included in addition to the requirements based on this performance specification template Product specification writers may add specification parameters and/or groups of specification parameters for particular applications However, product specification writers should not remove specification parameters specified in this standard N o rm a t i v e re fe re n c e s The following documents, in whole or in
