1 Scope

GB/T 16849-2023 is the Chinese national standard on generic specification of optical amplifier, in the field of telecommunications and audio-video engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 17 March 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 October 2023. Classification: ICS 33.180.30, CCS M33. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document defines the terms and definitions of optical amplifiers (OA), specifies the classification and requirements of optical amplifiers, and describes the corresponding tests method: This document applies to rare earth element-doped active fiber OA devices, optical amplifier subsystems, and Raman fiber amplifiers (RFA) device design, development, production and testing:
