请教怎么在独立屋里布网络线

如果房子已经建好了,最好利用已有的线路。像楼上有人说的,首先检查你的现有布线是cat5还是cat5e.如果是后者,和cat6效果是一样的。其次,你的高清播放器能播1000M的媒体吗?你的高清信号源需要1000M速率吗?如果100M就够了,就没有必要用1000M速率的。第三,需要每个房间都用1000M吗?如果只是从一个房间播放,另一个房间接收,就用现有的电话线路(cat5/cat5e)通过basement的接线板连接就行了。
 
我的房里用的是cat5e线,但是我是想布千兆网。所以8根线全部都要用。而且用的是DSL, 电话线还得占用。


以太网只用4根线,其余两根用作电话线(和DSL),另外闲置两根,可用做POE的电源。
 
请问是哪4根线?在RJ45头什么位置上?
 
1000Mbps 只是理论带宽,
实际吞吐能到6,700Mbps 就不错了。
再去掉各层协议开销,80MBps吧。
除了看高清文件,拷贝文件也比百兆网快很多。

在网线长度小于100米时,Gigabit Ethernet 用cat5e与cat6区别不大。如果只在独立屋内布网,Gigabit switch/rouyer放地下室, 那么每根线的长度不会大于100米。

正如sip说的,cat5,cat5e,cat6,cat6a,cat7,cat7a网线都只用4根线。

8P8C - Wikipedia, the free encyclopedia

The 8 Position 8 Contact (8P8C, also backronymed as 8 position 8 conductor; it is often incorrectly called RJ45)[1] plugs and sockets are most regularly used as an Ethernet connector.[2] 8P8C connectors are typically used to terminate twisted pair cable.

8P8C are commonly used in computer networking, where the plug on each end is an 8P8C modular plug wired according to a TIA/EIA standard. These cables are typically used to connect Ethernet or Token Ring network interfaces. Most network communications today are carried over Category 5e or Category 6 cable with an 8P8C modular plug crimped on each end.

The 8P8C modular connector is also used for RS-232 serial interfaces according to the EIA/TIA-561 standard[1]. This application is commonly used as a console interface on network equipment such as switches and routers. Other applications include other networking services such as ISDN and T1.

In floodwired [3] environments the center (blue) pair is often used to carry telephony signals. Where so wired, the physical layout of the 8P8C modular jack allows for the insertion of an RJ11 plug in the center of the socket, provided the RJ11 plug is wired in true compliance with the U.S. telephony standards (RJ11) using the center pair. The formal approach to connect telephony equipment is the insertion of a type-approved converter.

The remaining (brown) pair is increasingly used for Power over Ethernet (PoE). Legacy equipment may use just this pair; this conflicts with other equipment as manufacturers used to short circuit unused pairs to reduce signal crosstalk. Some routers/bridges/switches can be powered by the unused 4 lines — blues (+) and browns (−) — to carry current to the unit. There is now a standardized scheme for Power over Ethernet.

Different manufacturers of 8P8C modular jacks arrange for the pins of the 8P8C modular connector socket to be linked to wire connectors (often IDC type terminals) that are in a different physical arrangement from that of other manufacturers: Thus, for example, if a technician is in the habit of connecting the white/orange wire to the "bottom right hand" IDC terminal, which links it to 8P8C modular connector pin 1, in jacks made by other manufacturers this terminal may instead connect to 8P8C modular connector pin 2 (or any other pin).

不是说千兆网 8根线都要用的吗?

对了,我今天找到那个分线盒了。
证实了所有电缆都用的cat 5e,
如果布百兆网的话,估计照前面大家说的,用其中四根线就够了。

但是如果千兆网要8跟线的话,我倒是想到一个办法。
只要能找到进来的电话线是哪根,把它从面板上断开,DSL modem 就直接接断开的线,然后剩下的线就可以用来组千兆网了。

目前问题是 我分不出来哪根是进来的电话线,请问有没有办法找出来?


还有现在的面板似乎是用作 语音的,有没有必要把线用leviton 专门连 data 的面板再连一遍?


Correct!
 
还有即使千兆网要用8根线, DSL 信号才几兆赫兹, 千兆网信号频率应该高得多,放到同一根缆上跑,不知道行不行。
 
... GE requires 250MHz bandwidth (4 pairs)
FE only needs 100MHz bandwidth (2 pairs)


Where do you get extra bandwidth if you always only used 2 pairs?!?!

GE requires all 8 wires. Even if the "connected speed" says 1000 with 2 pairs, that's only the highest common denominator (both capable). But actual wire speed is reduced.

You can MAYBE modulate voice along with ethernet. But what's the point... DSL is a NONO for sure. Even running DSL/FE on the same CAT6 is doubtful, because of the possible noise components
 
看来对我来说最好的方案就是把电话线从面板断开,反正我不用常规电话,只用DSL。
然后其他的线我想可能最好也从面板上取下来,然后做好连接头,接在以太网交换机上,这样比原来的连接方式(实际上是hub连接方式)一个是干扰小,二个是吞吐量大些。

但是怎么样找进来的那根电话线呢? 我是看到了电缆上都有标号,怎么找Bell公司的分线盒呢? 它一般在什么地方? 那个ADT盒子出来的线是不是接的电话线?

把楼下所有电话线断开找24伏

有电压的就是电话局来的
 
太固执了。

他可能是不太明白。
PLA,follow these steps:
1到你的basement的接线板,看电话线都接到哪两根cat5e中的线了,通常是蓝色的和蓝花的。
2到homedepot 买几个电话线加ethernet网的接线盒,双口的,取代你现有的电话单口接线盒,需要几个
买几个。
3把那两根电话线,还接到电话插头上,剩下的1,2,3,6接到你的ethernet接头上。这样,每个屋
子都有电话和以太网接头了。
如果你的路由器(router,/switch)在basement, 就可以直接连接到每个房间的cable上。Homedepot有卖
这样的带socket的接线板。如果是从一个房间到另一个房间,只要找出相应的cable,把对应的4根线连起
来,就行了。
