电信的生成AI底漆
摘要 - 生成人工智能（Genai）的兴起正在改变电信行业。Genai模型，尤其是大型语言模型（LLMS），已成为能够推动创新，提高效率并在电信中提供卓越客户服务的强大工具。本文提供了从理论到实践的电信的Genai的概述。我们回顾了Genai模型，并讨论了他们在电信中的实际应用。此外，我们描述了有效地将Genai应用于电信的关键技术推动因素和最佳实践。我们强调了将LLMS连接到电信域特定数据源以增强LLMS响应的准确性时，检索增强生成（RAG）的重要性。我们提出了一个基于抹布的聊天机器人的真实世界用例，该案例可以回答开放式广播访问网络（O-RAN）特定问题。聊天机器人向O-Ran联盟的演示引发了对该行业的巨大兴趣。我们已经在Github上公开访问O-Ran Rag Chatbot。

塞浦路斯今日塞浦路斯电信 - Cytaglobal
塞浦路斯的电信历史始于 1870 年 11 月 9 日，当时决定通过英国“纽沃尔公司”铺设的海底电缆将塞浦路斯与拉塔基亚电报连接起来。电缆的塞浦路斯终端位于法马古斯塔东北部的卡帕西亚的 Ayios Theodoros。从那里开始，一个内部电报网络被建立起来，将 Ayios Theodoros 连接到尼科西亚，将尼科西亚连接到拉纳卡。当时，塞浦路斯的商业中心是尼科西亚和拉纳卡，拉纳卡也是该岛的主要港口以及所有领事馆所在的城镇。这条电报链路是塞浦路斯电信发展的第一步。1878 年，塞浦路斯受到英国殖民统治。同年，“东方电报公司”获得许可，安装一条新的电报电缆，通过其他海底电缆将拉纳卡与亚历山大港连接起来，然后与伦敦连接起来。这条电缆于 1878 年 10 月 19 日启用，没有使用任何中继器，其容量为一个电报信道。还建立了一个更全面的内部网络，连接六个主要城镇和特罗多斯山区，夏季期间政府官员和主要政府服务机构会迁往该地区。拉纳卡当时是塞浦路斯著名的商业中心，也成为新成立的电报通信中心。电报信息的传输基于手动系统 ca
毫瓦阈值可见电信光学参数...
在可见波长下片上创建相干光对于光谱和计量系统的现场部署至关重要。虽然在特定情况下已经实现了片上激光器，但是尚未报道不受特定增益介质限制的通用解决方案。在这里，我们提出使用硅纳米光子学通过宽分离的光参量振荡 (OPO) 从红外泵浦产生可见光。OPO 使用 900 nm 泵浦分别在 700 nm 和 1300 nm 波段产生信号光和闲置光。它以 (0.9 ± 0.1) mW 的阈值功率工作，比其他仅在红外领域报道过的宽分离微腔 OPO 工作小 50 倍以上。这种低阈值使得直接泵浦成为可能，而无需中间光放大器。我们进一步展示了如何修改设备设计以产生具有相似功率效率的 780 nm 和 1500 nm 光。我们的 nanophotonic O PO 在功率效率、操作稳定性和设备可扩展性方面表现出了独特的优势，并且是朝着灵活地在芯片上产生相干可见光迈出的一大步。
