8、primarily those used in digital systems. Applications include both single-channel and multi-channel systems used in point-to-point and point-to-multipoint configurations for use in long-distance networks and optical access networks. The purpose of this Recommendation is to identify which aspects sho
9、uld be considered for each application and to specify appropriate parameter values and ranges for each type of OA device. In this version of this Recommendation, information about non-linear optical effects in Appendix II is updated. Amendment 1 adds a new clause II.3.4 to Appendix II for cross-pola

12、1000/11830-en. ii Rec. ITU-T G.663 (2011)/Amd.1 (09/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T)
13、is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years
14、, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necess
15、ary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However,
16、 the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equ
17、ivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a c
18、laimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU ha
19、d received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/IT

26、 publication. Modifications introduced by this amendment are shown in revision marks relative to Recommendation ITU-T G.663 (2011). 1 Scope This Recommendation covers application-related aspects of optical amplifier (OA) devices and subsystems, primarily those used in digital systems. Optical amplif
27、iers operating in the 1550 nm region, or 1310 nm region, or other wavelength regions are included. Generic characteristics of OA devices and subsystems are described in ITU-T G.662. Applications include both single-channel and multi-channel systems used in point-to-point and point-to-multipoint conf
28、igurations for use in long-distance networks and optical access networks. The purpose of this Recommendation is to identify which aspects should be considered for each application and to specify common parameter values and ranges for each type of OA device (booster amplifier, pre-amplifier, and line
29、 amplifier). This Recommendation pertains to the development of new equipment including OA devices and includes guidelines to apply OA devices and OA subsystems to existing equipment. As an objective, for systems specified as transversely compatible, the degree of compatibility should not be changed
30、 by the use of OA devices. Important topics contained in this Recommendation include transmission aspects, maintenance aspects, and optical safety. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of
