高校全场景智慧教室建设方案：场景矩阵与python-pptx自动化生成
在高校信息化与多媒体教室升级中，智慧教室建设方案本质上是一套围绕教学行为的系统工程。其原理是先建立场景矩阵，把讲授型大教室、小班研讨室、录播教室、远程互动教室等空间的空间形态、音视频系统、网络算力与平台功能定档，再通过数据与版式分离，用 python-pptx 将场景清单灌入母版，批量生成可交付的 pptx。技术价值在于统一设备清单、预算与验收口径，降低多校区多版本手改出错率。应用场景覆盖高校智慧教室建设、录播与远程互动教室改造、中控与拾音扩声落地。全场景智慧教室从场景拆解、自动化生成到评审自检，形成一条可

Fifty-five km reach, bidirectional, 400 Gb/s (40 \times 10 Gb/s), channel-reuse DWDM–PON employing a self-wavelength managed tunable laser
We experimentally demonstrate a channel-reuse bidirectional 10 Gb/s/\lambda long-reach dense wavelength-division multiplexing passive optical network (DWDM-PON) and an optical beat-noise-based automatic wavelength control method for a tunable laser used in a colorless optical network unit (where \lambda=wavelength). A 55 km, bidirectional, 400 Gb/s (40 \times 10 Gb/s) capacity channel-reuse transmission with 100 GHz channel spacing is achieved. The transmission performance is also measured with
Upstream dispersion management of 25 Gb/s duobinary and PAM-4 signals to support 0–40 km differential reach
We extensively discuss 25 Gb/s per wavelength capacity in both IEEE and ITU-T standardization to support the increasing bandwidth requirement. In this Letter, we propose to use the optical dispersion compensation technique in an optical line terminal (OLT) combined with a bandwidth-limited electro-absorption modulated laser in an optical network unit to achieve 25 Gb/s capacity for the upstream link. We evaluate the positive and negative dispersion tolerances of 25 Gb/s electrical duo-binary (ED
