In the diverse global landscape of telecommunications, the technical requirements imposed by telecom operators for Ethernet cards exhibit distinct features across various countries. This article delves into the unique demands driven by technical considerations, as well as the specific needs and challenges arising from the diverse network topologies deployed by telecom operators worldwide.


The Ethernet card is a network interface card that supports Ethernet standards and protocols to realize data transmission and processing. The technical characteristics of Ethernet cards mainly include transmission rate, transmission distance, transmission medium, compatibility, power consumption, size, weight, etc. Telecom operators in different countries may have different technical requirements for Ethernet cards, which mainly depend on factors such as their network size, network services, network environment, and network costs.

Generally speaking, the network topology of telecom operators in different countries can be divided into three layers: access layer, aggregation layer and core layer. The access layer refers to the network equipment connected to user terminals, such as optical fiber terminals, wireless base stations, etc. The aggregation layer refers to the network devices connected to the access layer devices, such as switches, routers, etc. The core layer refers to the network equipment connected to the aggregation layer equipment, such as backbone network switches, backbone network routers, etc. Different levels of network equipment may have different technical requirements for Ethernet cards, which mainly depend on their network performance, network efficiency, network reliability and other factors.

I summarized the following points:

? At the access layer, the technical characteristics required by telecom operators in different countries for Ethernet cards are mainly low speed, short distance, multi-media, high compatibility, low power consumption, small size, and light weight. This is because network equipment at the access layer needs to cover a wide range of users, adapt to a variety of network environments, provide a variety of network services, and reduce network costs and maintenance difficulties. For example, network equipment at the access layer may need to use 10G or 25G Ethernet cards, support 100m or 1km transmission distance, support multi-mode optical fiber, single-mode optical fiber, copper cable and other transmission media, support PCIe, USB and other interface types, support low With a power consumption of 10W, it supports a weight of less than 100g.


? At the aggregation layer, the technical characteristics of Ethernet cards demanded by telecom operators in different countries are mainly medium speed, medium distance, single medium, medium compatibility, medium power consumption, medium size, and medium weight. This is because network devices at the aggregation layer need to connect multiple access layer devices to improve network performance and efficiency, ensure network reliability and security, and balance network costs and maintenance difficulty. For example, network equipment at the aggregation layer may need to use 40G or 50G Ethernet cards, support transmission distances of 10km or 40km, support transmission media such as single-mode optical fiber or copper cables, support interface types such as PCIe and QSFP, and support power consumption below 20W. , supports weights below 300g.

? At the core layer, the technical characteristics of Ethernet cards demanded by telecom operators in different countries are mainly high speed, long distance, single medium, low compatibility, high power consumption, large size, and heavy weight. This is because the core layer network equipment needs to connect to multiple aggregation layer equipment to provide high-speed, efficient, and highly reliable network transmission and processing to meet high-end network services and applications, while also being able to withstand higher network costs and maintenance difficulties. For example, core layer network equipment may need to use 100G or 200G Ethernet cards, support 80km or 120km transmission distance, support transmission media such as single-mode optical fiber or DWDM, support PCIe, CFP and other interface types, and support power consumption higher than 30W. Supports weights above 500g.


The needs and challenges brought by the network topology of telecom operators in different countries mainly include the following aspects:

? Network planning and design. Telecom operators need to reasonably plan and design the network topology according to their own network goals and development strategies, and select appropriate network equipment and Ethernet cards to achieve network coverage and expansion, improve network performance and efficiency, and ensure network reliability. performance and security, taking into account the costs and benefits of the network.

? Network deployment and operation. Telecom operators need to effectively deploy and operate network equipment and Ethernet cards according to the network topology to achieve normal operation and optimization of the network, solve network faults and problems, meet users' network needs and services, and reduce network Risks and Losses.

? Network upgrades and innovations. Telecom operators need to promptly upgrade and innovate network equipment and Ethernet cards based on the network topology to adapt to network changes and development, support new network services and applications, enhance the competitiveness and influence of the network, and at the same time increase the network's revenue and profits.
