首先我們先看看萬兆網線及千兆光纖的區別，否則無法定義它倆哪個更好。

首先看看萬兆網線：

萬兆網線是七類線，它的特徵是每對雙絞線都帶有遮蔽層，是對對遮蔽。

萬兆網線的標識如圖：

萬兆支援千兆 / 萬兆乙太網

目前國內的話，跑萬兆的就是超六類網線了，即CAT6A

1. 標準

萬兆網線:指的是七類線,ISO/IEC 11801 7類/F級標準中最新的一種雙絞線,主要為了適應萬兆位乙太網技術的應用和發展。

2. 速度

萬兆網線:可以提供至少500MHZ的綜合衰減對串擾比和600MHZ的整體頻寬,是六類線和超六類線的2倍以上傳輸。

3. 結構

萬兆網線:是一種8芯遮蔽線,每對都有一個遮蔽層(一般為金屬箔遮蔽。

4. 使用範圍

在公司通訊裝置、網路裝置（交換機和路由器）機房內，用於通訊裝置、網路裝置之間通訊聯結線及樓層交換機連線，最長不能超過100米。

然後咱們看看千兆光纖：

千兆光纖光纖本身是不分千兆萬兆的，因為它只是資料傳輸的介質，光纖傳輸的快慢取決於通訊交換機的光模組。

我們生活中所說的千兆萬兆光纖，其實說的光膜塊（也就是光纖埠）。光纖分為單模光纖和多模光纖。

首先單模光纜是不分千兆還是萬兆的，單模佈線是千兆速率還是萬兆主要取決於它使用的裝置，正常情況下單模光纜透過裝置的支援，工作在1550μm波長下的光單模光纜可以支援萬兆（10Gbps)至少達60公里。

多模光纜。根據傳輸速率的不同，又分為OM1,OM2,OM3,OM4。其中OM1的光纜纖芯直徑為62.5μm，OM2至OM4的纖芯直徑均為50μm。其實光纖分為兩種，一種是單芯光纖，一種是雙芯光纖。我們先從單芯光纖說起。

單芯光纖一般用於單芯光纖的光貓和單芯光收發器。一般家庭裡用的都是單芯的光纖光貓。為了進行區分，單芯的光纖使用不同的波長來進行下載和傳輸。舉個例子，如果用1310毫米的波長進行上行資料的傳輸，那麼下行資料的傳輸波長則為1490毫米。

在傳輸距離超過100米後，網線一般就很少被使用了，更多的是使用光纖，比起光貓。收發器的單芯光纖一般都是成對使用但比便如此，比起雙芯光纖，因為少了一根光纖的緣故，成本上還是便宜了不少。

然後就是雙芯光纖。

從字面上來看，雙芯光纖就是有兩條光纖，一條用於傳送，一條用於接收。其他的方面並沒有多少差別，也很少與單芯光纖進行對比，因為它們通常使用在不同的領域。但雙芯光纖常常被拿來與雙絞線進行對比。

此外，企業使用的交換機上，光口是要配合相關部件使用的，相比起雙絞線，光纖的介面速度達到了千兆甚至更高，極大方便了連線。

所以，綜合上述，如果使用在中心機房，進行網路裝置接的聯結，萬兆網線，千兆雙模光纖都可使用，當然網路裝置需提供萬網埠和千兆光纖模組。現在流行的H3C-5750的交換機及 H3C -8680的路由器，銳捷高階交換機都提供了這兩種網路埠，可根據需要進行網路裝置的聯結。而單模光纖多用於城區，縣域等遠距離，透過光端貓與光端機之間通訊。僅供參考。

下面，我把它翻譯成英文

Which is better, 10 gigabit cable or 1 gigabit fiber?

First let"s look at the difference between a 10 gigabit cable and a gigabit fiber, otherwise it"s impossible to define which is better.

First, look at the 10 gigabit cable:

10 million network cable is seven types of lines, it is characterized by each pair of twisted pair with shielding layer, is a pair of shielding.

The mark of ten million network cable is as follows:

10 gigabit support for gigabit / 10 gigabit Ethernet

At present domestic words, run ten thousand trillion is more than six kinds of network cable, namely CAT6A

Standard 1.

10 gigabit cable: refers to the seven classes of cables, the latest twisted pair in ISO/IEC 11801 class 7 /F, which are mainly used for the application and development of 10 gigabit Ethernet technology.

Speed of 2.

10 gigabit network cable: it can provide at least 500MHZ of integrated attenuation to crosswalk ratio and 600MHZ of overall bandwidth, which is more than twice the transmission of class 6 and superclass 6.

Structure of 3.

10 million network cable: it is a kind of 8-core shielding wire, each pair has a shielding layer (generally foil shielding).

4. Scope of use

In the machine room of the company"s communication equipment and network equipment (switches and routers), the communication connection line between the communication equipment and network equipment and the floor switch connection shall not exceed 100 meters.

Then let"s look at gigabit fiber:

Gigabit fiber itself is not divided into gigabit, because it is only the medium of data transmission, the speed of fiber transmission depends on the optical module of the communication switch.

What we call gigabit, gigabit fibers in our lives are actually lumps of optical film.Fiber is divided into single-mode fiber and multi-mode fiber.

First of all, single-mode optical cable is not divided into gigabit or 10 gigabit, single-mode wiring is gigabit rate or 10 gigabit mainly depends on the equipment it USES, under normal circumstances, single-mode optical cable through the support of equipment, working at 1550 nm wavelength optical single-mode optical cable can support 10 gigabit (10Gbps) at least 60 km.

Multimode cable.According to the transmission rate, it is divided into OM1,OM2,OM3 and OM4.Among them, the fiber core diameter of OM1 is 62.5 micrometers, and the core diameter of OM2 to OM4 is 50 micrometers.In fact, there are two kinds of fiber, one is single-core fiber, the other is double-core fiber.Let"s start with single-core fibers.

Single-core optical fiber is generally used in single-core optical fiber optical cat and single-core optical transceiver.Most homes use single-core fiber optic cats.To differentiate, single-core fibers use different wavelengths for download and transmission.For example, if the uplink data is transmitted at a wavelength of 1310mm, the downlink data is transmitted at a wavelength of 1490mm.

After transmission distances of more than 100 meters, network cables are generally used less, and more often, fiber optics than light cats.The single-core fiber of the transceiver is usually used in pairs, but this is the case because one fiber is less expensive than the dual-core fiber.

And then there"s the two-core fiber.

A two-core fiber is literally two fibers, one for sending and one for receiving.Other aspects are not much different and are rarely compared to single-core fibers because they are often used in different fields.But twin-core fibers are often compared to twisted pair wires.

In addition, the switch used by the enterprise, the optical port is to be used with related components, compared with the twisted pair, the interface speed of the optical fiber reached gigabit or higher, greatly facilitate the connection.

Therefore, on the basis of the above, if it is used in the central machine room, it can be used for connection of network equipment, such as ten thousand megabits of network cable and gigabit dual-mode fiber. Of course, the network equipment shall provide ten thousand network ports and gigabit fiber modules.Now the popular h3c-5750 switch and h3c-8680 router, ruijie high-end switches provide these two network ports, according to the need for network equipment connection.The single-mode fiber is mainly used for long-distance communication between the optical terminal and the optical terminal in urban areas and counties.

光纖更好，但主要看你需求。光纖連線裝置是千兆就是千兆速率，萬兆就是速率。千兆網線不同於萬兆網線，萬兆網線能用在千兆裝置上，但千兆網線用在萬兆裝置上只有千兆速率。相對來說對於家庭更傾向於萬兆網線，便宜；單位是光纖，方便。
