Title: Up-to-Date Shanxi Communications Cable Specification Table

Shanxi Province, located in northwest China, is a key communication hub with diverse topography and climate. To ensure the efficient and reliable transmission of data, Shanxi Communications Cable Specification Table has been developed to meet the specific needs of the region. This table specifies various types of communication cables that can be used in different applications, including fiber optic cable, coaxial cable, and twisted pair cable. It also provides detailed information on the minimum requirements for cable length, bandwidth, and other factors such as signal attenuation and interference. By following this table, engineers and technicians can select the most appropriate cables for their projects and ensure that they meet the specified standards. In addition to improving communication quality, this specification table can also help to reduce costs and minimize downtime by ensuring that cables are properly installed and maintained. Overall, the Up-to-Date Shanxi Communications Cable Specification Table is an essential resource for anyone involved in communications infrastructure in Shanxi and beyond.

Communications cables play a critical role in the transmission of information and energy within a network. They connect various devices, such as computers, servers, routers, and switches, allowing data to be transmitted quickly and efficiently. In China, particularly in the northern regions, where the population is dense and the demand for communication infrastructure is high, the use of communication cables is prevalent. Among these cables, communication cables made of copper or fiber-optic material are the most commonly used. This article will focus on the latest specification table for communication cables in Shanxi province, China.

Shanxi Province is located in the northwest of China and has a long history of communication development. The province has seen rapid growth in recent years, with an increasing demand for communication infrastructure. To meet this demand, the provincial government has been investing heavily in the construction of communication networks, including upgrading existing infrastructure and installing new lines. As a result, there has been a surge in the production and use of communication cables in Shanxi.

In order to ensure that the communication cables being used meet the necessary standards and specifications, it is essential to have a comprehensive understanding of the latest specification table. The following sections provide an overview of the key features and components of communication cables in Shanxi, along with their respective specifications.

1. Copper Communication Cables (Category 5)

Copper communication cables are widely used in China due to their low cost and good performance. Category 5 copper communication cables are designed for short-distance transmission and can handle up to 100MHz frequency bandwidth. The following are the key specifications for Category 5 copper communication cables:

* Conductor: Pure copper, diameter 1.2mm

* Jacket: Polychloroprene (PVC), thickness 0.6mm

* Covering: PVC, thickness 0.4mm

* Max operating temperature: -30°C ~ 70°C

* Min operating voltage: DC 48V

* Max operating frequency: UHF (50Hz~1GHz)

* Min guard radius: > 75% of cable length

In Shanxi province, Category 5 copper communication cables are commonly used for domestic and small-scale commercial purposes. However, for larger-scale applications such as internet service providers (ISPs) and data centers, Category 5e copper communication cables with higher shielding levels may be required.

1. Fiber Optic Communication Cables (Category 6A/B/C)

Fiber-optic communication cables offer higher bandwidth, lower signal loss, and greater distance stability compared to copper cables. They are mainly used for long-distance transmission and can handle frequencies from几十MHz to几千MHz. The following are the key specifications for Category 6A/B/C fiber-optic communication cables:

* Core: Single-mode fiber with core diameter of 9μm, 12μm, or 62.5μm

* Jacket: Polyamide (PA) with an inner diameter of 25μm or larger

* Covering: Polycarbonate (PC) with an outer diameter of 20μm or larger

* Operating temperature: -10°C ~ 65°C

*operating humidity: <=95%RH(non-condensing)

* Max operating frequency range: UHF (50Hz~1GHz) or VHF (1GHz~30GHz) depending on core type and wavelength

* Min guard radius: >50% of cable length for indoor use; >80% of cable length for outdoor use

In Shanxi province, fiber-optic communication cables are commonly used in areas where there is a need for long-distance transmission, such as between cities or between provinces. For example, fiber-optic communication cables are often used to connect Beijing to Taiyuan, Shanxi's capital city, for faster data transmission and lower latency. Additionally, fiber-optic communication cables may also be used in areas where there is a significant amount of traffic on copper cables, such as in urban centers or near large buildings.
