光缆线路施工的特点
光缆线路施工的特点
Characteristics of optical cable line construction
1光缆的制造长度较长
The length of the 1 optical fiber cable is longer
一般光缆的标准制造长度为2km(有时也可根据用户要求来确定),70公里以上的超长中继段的埋式光缆为2km。
The standard manufacturing length of the general optical cable is 2km (sometimes can be determined according to user requirements), and the buried cable of over 70 kilometers long relay section is 2km.
2光缆的抗张能力较小
The tensile ability of 2 optical cables is small
光缆所需的抗张强度,主要由加强构件来承担。
The tensile strength required for optical cables is mainly borne by reinforced components.
一般光缆的抗张力为100~300kg,而直埋光缆为600~800kg,特殊光缆(如水底光缆)由光缆制造设计部门提出抗拉强度值。
The tensile strength of the optical fiber cable is 100 ~ 300kg, while the direct buried optical cable is 600 ~ 800kg. The special optical cable (such as the underwater optical cable) is proposed by the optical cable manufacturing design department for the tensile strength.

3光缆直径较小,重量较轻
3 fiber cable is smaller in diameter and lighter in weight
例如单模10芯以下的光缆,其直径在11mm以内,单位长度的重量在90kg/km以下。
For example, the diameter of the optical cable with a single core of less than 10 cores is less than 11mm, and the weight of the unit length is less than 90kg/km.
4光纤的连接技术要求较高,接续较复杂
4 the connection technology of optical fiber is higher and the connection is more complicated.
光纤的接续需要在高温下,将光纤端面熔融,然后靠石英玻璃的粘度而粘合在一起。因而,在连接时需用的机具就较为复杂,而且技术要求也比电缆高。
The optical fiber needs to melt at the high temperature, melt the fiber end, and then adhere to the viscosity of the quartz glass. Therefore, the equipment needed to connect is more complicated and the technical requirement is higher than that of the cable.
