随着应用规模的扩大,FTTH设备以及固线的成本有极大的下降空间。在业务融合上,从过去能够提供普通的电话业务到广播电视,如高清晰电视、流媒体到现在目前正在实践的FTTH,今后宽带市场的走向一定时间内会出现ADSL、FTTB+LAN、FTTH共存,短时间内ADSL将持续占主流,DSL和FTTH将会共同发展。在FTTH设备价格由于建设量的增大而逐步降低到DSL的水平后,FTTH市场容量将会大量增加。

Media Gateway 用于监控车载以太网通信,以太网端口测试,CAN/LIN/Flexray与100Base-T1路由测试等;在BMW,AUDI,BOSCH以及国内多公司大量使用; MediaGateway from Technica Engineering is a development tool for testing and analyzing on-board vehicle networks. MediaGateway from Technica Engineering is the most widely used development and testing tool for on-board vehicle networks using 100BASE-T1. It’s in-built automotive switches and 12 x 100BASE-T1 ports enable both capture of traffic between devices while maintaining the normal communication, as well as interaction with such devices via your test set-up. It supports single and double tagging of VLANs, Mirroring, Forwarding and more. MediaGateway is excellently suitable for subsystem testing stations and can also be installed in a test vehicle without complications. It is configured conveniently via a browser through the integrated web server. An additional and optional CAN-Ethernet bi-directional conversion is available, as well as FlexRay logging via Ethernet and one SFP slot. The SFP slot supports commercial-grade SFP modules (e.g. optical or RJ-45) as well as our 100BASE-T1 SFP Module in order to get a 13th Automotive Ethernet Port or our 1000BASE-T1 SFP Module – this makes the MediaGateway ready for Automotive Gigabit Ethernet! 12 Broadcom 100BASE-T1 ports (100 MBit/s full duplex on a single unshielded twisted pair) 3 Gigabit Ethernet ports 1 SFP Gigabit Ethernet port Automotive Tyco MQS connectors for 100BASE-T1 and power supply Web server for easy configuration: Master/Slave, HalfOut/FullOut, Port Forwarding, Port Mirroring, VLAN Tagging WakeUp function by CAN Bus or Wakeline Power output for attached devices: VBAT max. 1 Ampere in total 19 status LEDs Possibility to reset to default settings by pushbutton Robust steel case Power requirement: 8 to 16 V DC, power consumption: 8 Watt Size: 195 x 143 x 33 mm 802.1AS Bridge function

矩形栅格平面相控阵天线经常受到圆柱形设备的约束,本文研究设计了一种阵元非均匀分布排列的圆形口径相控阵天线方向图,建立数学模型并对其进行了公式推导和计算机仿真。同时与同等规模的矩形栅格平面相控阵天线方向图进行对比分析。分析表明,前者的半功率点波束宽度要小于后者,主瓣能量利用更加集中,提高了扫描性能,辐射能量大致相同的情况下,前者所需要的阵元数要少,节约了成本。
