光放大器. 试验方法. 第4-3部分: 功率瞬态参数. 输出功率控制中的单通道光放大器

[中文适用范围]： IEC 61290 的这一部分适用于输出功率控制的光放大基本子系统。它适用于使用含有稀土掺杂剂的有源光纤的光纤放大器（OFA）@目前已商用@如IEC 61291-1@中所示，以及可用于单通道输出功率控制操作@的替代光放大器，例如半导体光放大器（SOA）。本标准的目的是为光放大器 (OA) 功率瞬态及其测量提供一般背景，并指出准确可靠地测量以下瞬态参数的 IEC 标准测试方法： a) 瞬态功率响应 b) 瞬态功率过补偿响应 c) 稳态功率偏移 d) 瞬态功率响应时间 考虑的激励和响应行为包括： 1) 通道功率增加（阶跃瞬态） 2) 通道功率减少（逆阶跃瞬态） 3) 通道功率增加排出（脉冲瞬变） 4） 通道功率减少/增加（逆脉冲瞬变） 5） 通道功率增加扣除/增加（闪电瞬变） 6） 通道功率减少/增加扣除（逆闪电瞬变） 包含这些参数是为了提供输出功率瞬态控制 OA 瞬态行为的完整描述。如果放大器是 OFA 或替代 OA，则此处定义的测试定义适用。然而@本文件附件A中的描述集中于OFA的物理性能，并提供了OFA行为的详细描述；它没有给出其他 OA 类型的类似描述。 [外文原描述]： IEC 61290-4-3:2015(E) applies to output power controlled optically amplified, elementary sub-systems. It applies to optical fibre amplifiers (OFA) using active fibres containing rare-earth dopants, presently commercially available, as indicated in IEC 61291-1, as well as alternative optical amplifiers that can be used for single channel output power controlled operation, such as semiconductor optical amplifiers (SOA). The object of this standard is to provide the general background for optical amplifier (OA) power transients and its measurements and to indicate those IEC standard test methods for accurate and reliable measurements of the following transient parameters: - Transient power response; - Transient power overcompensation response; - Steady-state power offset; - Transient power response time. The stimulus and responses behaviours under consideration include: - Channel power increase (step transient); - Channel power reduction (inverse step transient); - Channel power increase/reduction (pulse transient); - Channel power reduction/increase (inverse pulse transient); - Channel power increase/reduction/increase (lightning bolt transient); - Channel power reduction/increase/reduction (inverse lightning bolt transient). These parameters have been included to provide a complete description of the transient behaviour of an output power transient controlled OA. The test definition defined here are applicable if the amplifier is an OFA or an alternative OA. However, the description in Annex A of this document concentrates on the physical performance of an OFA and provides a detailed description of the behaviour of OFA; it does not give a similar description of other OA types.
