揭秘智能网络
As cable operators upgrade their network infrastructure to meet the rising capacity demands, there are opportunities to bring more intelligence into networks as well. Many of our customers have used the 智能网络 技术 for quite some time already. 与 large-scale distributed access deployments gradually growing, now is the perfect time to focus on what it would mean to make cable networks intelligent for those operators that have not yet done so.
简而言之， 智能网络 comprises advanced optical nodes and amplifiers in a cable access network. 传统上, these network elements have been aligned manually, meaning that a technician visits the site with a measurement device and a bunch of plugin equalisers and attenuators to manually align the signal levels as needed for the optimal network performance.
与 智能网络, 十大可靠彩票平台基本上把这些都自动化了. We have integrated many sensors in our amplifiers and nodes that measure a high number of parameters, 比如信号电平, internal temperature and power consumption, 例如. We have also developed algorithms and software turning the sensor data into automatic adjustments of the network elements. All these electronic adjustments and measurement capabilities allow exposing the network elements to remote control, monitoring and troubleshooting from the network operating centre.
建立公司的好处 智能网络 技术 can be concisely described under the banner ‘automation’. 最近, when talking about automation in the cable industry, the term has started to refer to software and cloud-based technologies. We, 然而, have introduced automation way ahead of these solutions by placing the 技术 in the network elements themselves.
Cable network operators are always looking for ways to improve the efficiency and performance of their networks. 智能网络 技术 is ready to help them achieve these goals.
Among the benefits realised by the 技术 is automatic ingress detection and suppression, allowing the detection of ingress in any coax port and then suppressing the ingress automatically to narrow the disturbance to a limited set of subscribers. This improves service availability for subscribers and allows the operator to reduce truck rolls to hunt for the locations where ingress enters the network.
另一个好处的例子是 同轴网络中的分频变化 这和 智能网络 技术, is a very simple operation carried out by a technician visiting the site and swapping the diplexer filter modules. The amplifier then automatically detects the new modules and aligns itself to the optimal level without any intervention from the technician. 再一次。, it is a very fast field operation with a very short service outage and a very quick truck roll.
当涉及到 设备功耗, the 技术 allows detecting the actual network load from amplifiers and nodes, which is typically much lower than the device is capable of managing. 例如，下一个1.8 GHz放大器的容量更大, and it will likely be used only partially for the first years. The intelligent amplifier can detect how much load there actually is and, 如果不是最大值, the bias current to the gain blocks can be adjusted down and significant power savings can be achieved. Our measurements show that up to 20% of the total network power consumption can be realistically saved by utilising the 技术.
In 1.8ghz网络, the capacity of the coax downstream system will be limited by the total composite power capacity of the amplifiers. 与 自动液位调节, the amplifier levels can be kept very close to the optimum level regardless of the temperature variations in the outside plant. 当水平达到最佳时, the network can operate much closer to the maximum total composite power capacity of the amplifiers. The perfect alignment and stability of the downstream system, 反过来, 给你每秒更多的千兆比特.
上游, 哪一个会扩展到200兆赫, 400兆赫甚至更高, the temperature compensations are just as important because of the much wider upstream spectrum than operators have used so far. When the intelligent amplifier knows the optimum levels for the downstream, the 技术 utilises algorithms and rules to define 最佳水平设置 for the upstream and maintain them very accurately. 再一次。, 运营商的好处是, 用同样的网络, 每秒有更多的千兆位, which this time is from subscribers towards the network.
