The gain spectrum of F-EDF-2 (manufacturer P/N I-5 (980/125)) has been designed to generate a substantially flattened wavelength response that closely matches that of other leading fiber types. This intrinsic flatness and compatibility both simplifies the design of gain flattening filters (GFFs) and facilitates multi-sourcing by enabling the re-use of existing component stocks. Its core composition also promotes rapid mode-expansion during fusion-splicing, optimizing power output and noise figure and simplifying gain-module manufacture. This product offers an identical gain spectrum every time, with maximum batch-batch absorption variability just 0.00025 dB/m. This model replaces the legacy model F-EDF-T3. Standard pricing is per meter.

F-EDF-2(制造商P/N I-5(980/125))的增益谱被设计成产生与其他主要光纤类型接近的基本平化波长响应。这种固有的平整度和兼容性既简化了增益变平滤波器(GFFs)的设计，又通过重用现有组件库存促进了多方采购。其核心组成也促进了熔接过程中的快速模态扩展，优化功率输出和噪声图，简化了增益模块的制造。该产品每次都提供相同的增益谱，最大的批批吸收变异性仅为0.00025 dB/m。这个模型替换了旧模型F-EDF-T3。标准价格是每米。
