摘要： Disclosed are a system and techniques to determine a color of an optical fiber in a fiber optic cable. A spectrophotometer camera may obtain a color value of the optical fiber. A fiber adaptor is operable to hold a single optical fiber of a fiber optic cable in a field of view of the spectrophotometer camera. A memory storing instructions that, when executed by a processor, enable identifying a color of the optical fiber. The color value may be compared to a color value of a number of reference colors. A color match score value may be generated for the color value with respect to each reference color. A confidence value may be obtained for a pair of color match scores that are closest in score value. Based on the confidence value, one of the reference colors is identified as a color of the optical fiber.

摘要： A system and method for efficient optical signal amplification with system monitoring features are provided. For example, an optical repeater may include two different 4-port thin-film gain flattening filters (TF-GFFs), which may be connected to provide a high-loss loop-back (HLLB) path in the optical repeater for system monitoring. The 4-port TF-GFF may have four different ports and may integrate the functionalities of a conventional GFF and a coupler into a single component, thereby increasing power efficiency of the optical repeater.

摘要： Techniques for managing gain equalization error in optical communication systems are provided. For example, a multi-stage gain correction filter may be configured to at least correct gain equalization error produced by filters with insufficient resolution, for example, conventional non-reflective gain correction technology used in the optical communication systems. The multi-stage filter may include at least a broadband gain correction filter to correct gain equalization error in most of the transmission bandwidth and a narrow band gain correction filter to correction error in a narrow region of the bandwidth. One or more of the multi-stage filters may be implemented in the repeaters of the system (which may be referred to as hybrid GFFs) or may be included in a standalone body (which may be referred to as hybrid GEFs).
