0-57510 使用屏蔽双绞线 

【产品详情】

0-57510工业现场布置以太网时对电缆有什么要求?

在工业现场布置以太网时，可以使用屏蔽双绞线

(STP)、非屏蔽双绞线(UTP) 和光

纤。可以使用5类、 5e、 6类和6e 的双绞线。电缆的等级越高，它的性能就越好，

所需的EMC 保护就越少。推荐

100M时使用5e 以上的双绞线，1000M 推荐使用6

类以上的双绞线。使用光纤具有更强的噪音抗扰性，可以传输更长的距离。

 双绞线和光纤的传输距离

在常温( 20度)下，交换机与网卡间的双绞线最大传输距离为

100米，当线缆

的温度上升时，信号就会衰减，导致传输距离变短:当电缆周围干扰比较大时，也

会传输距离变短，因此实际安装时应该小于90米。

光纤可传输更长的距离，多模光纤在

100M的速度下可以传输2km，多模光纤

在1000M的速度下使用直径为50um 的光纤可以传输550m， 多模光纤在1000M 的速度下使用直径为

62. .5um的光纤可以传输220m。.

单模光纤可以传输距离为10km。

光纤的实际传输距离与光纤模块、光纤的类型和直径以及光纤安装时的弯曲半径有关。

【英文介绍】

What are the requirements for cables when laying out Ethernet in industrial sites?

Shielded twisted pair cables can be used to arrange Ethernet in industrial sites

(STP), unshielded Twisted pair (UTP) and light

Fuck. Class 5, 5e, 6 and 6e twisted pairs can be used. The higher the grade of the cable, the better its performance,

The less EMC protection you need. Recommended

Use a twisted pair of more than 5e when 100M, and 6 is recommended for 1000M

Class above twisted pair. The use of optical fiber has greater noise immunity and can be transmitted over longer distances.

The transmission distance between twisted pair and optical fiber

At room temperature (20 degrees), the maximum transmission distance between the switch and the network adapter is

100 meters, when the cable

When the temperature rises, the signal will attenuate, resulting in a shorter transmission distance: when the interference around the cable is relatively large, it is also

The transmission distance will be shorter, so the actual installation should be less than 90 meters.

Optical fibers can transmit longer distances, and multi-mode fibers in

It can transmit 2km of multi-mode fiber at 100M speed

Optical fibers with a diameter of 50um at 1000M speed can transmit 550m, and multi-mode optical fibers with a diameter of 1000M speed

62.. 5um optical fiber can transmit 220m. .

Single-mode fiber can be transmitted for a distance of 10km.

The actual transmission distance of the fiber depends on the fiber module, the type and diameter of the fiber, and the bending radius of the fiber when installed.
