时下,宽带社区的建设很时髦,刚刚启动的“家庭上网”工程必将再为此推波助澜。在社区接入 Internet的方式(ADSL、Cable Modem和以太网等)中,以太网占了上风。然而,由于 10/100Mbps以太网交换机传输距离最远为 100m,而很多社区中的一些住户到社区网络中心的距离会超出这个距离,所以宽带社区的建设普遍采用了光纤到楼,以太网到户,在每个楼层安装1台交换机的方式。毋庸置疑,光纤的使用、交换机数量的增多会大大增加建设成本。那么,10/100Mbps以太网交换机传输距离能否突破100m的限制呢?答案是肯定的,常州电信局小区采用了长线以太网交换机实现了宽带接入,找到了宽带社区建设的新思路。这无疑在当前宽带用户还比较少的情况下,具有很广泛的应用价值。
Nowadays, the construction of broadband community is fashionable. The newly launched “Home Internet” project will no doubt be further promoted. In the community access to the Internet (ADSL, Cable Modem and Ethernet, etc.), Ethernet prevail. However, since 10 / 100Mbps Ethernet switches have a maximum transmission distance of 100m and many of the residents in many communities are far away from the community hub, broadband community building has generally adopted fiber-to-the-floor, Ethernet-to-the-home , Install a switch on each floor of the way. Needless to say, the use of optical fiber, the increase in the number of switches will greatly increase the cost of construction. Then, 10 / 100Mbps Ethernet switch transmission distance can exceed the 100m limit? The answer is yes, Changzhou Telecom Bureau district using a long-term Ethernet switch to achieve broadband access, to find a new broadband community building ideas. This undoubtedly has a very wide range of application values under the current circumstances where the number of broadband users is still relatively small.
