Application Case of Terminal Wires in Communication Equipment

I. Case Background

In modern communication networks, switches in data centers are crucial for data exchange and transmission. Their stable operation relies on reliable internal connection components. As commonly used connection components, terminal wires play an important role. This case focuses on the application of terminal wires in high - performance switches of a well - known data center.

II. Communication Equipment Situation

The switch features a high - density port design and has the ability to exchange data at a high speed with a network bandwidth of 10 Gbps or higher. Its internal structure is compact, and the modules are arranged closely, requiring a flexible and reliable connection method to achieve communication and power supply between modules.

III. Application Details of Terminal Wires

(I) Signal Transmission

The Molex 51880 series of flat flexible terminal wires are used between the switch motherboard and the port modules. This series of products is specifically designed for high - speed signal transmission. The wire cores are treated with a unique silver - plating process, which greatly reduces resistance and capacitance and effectively reduces signal delay and attenuation. At the same time, it has a multi - layer shielding structure that can resist the complex electromagnetic interference inside the switch and ensure the accurate transmission of high - speed data signals, fully meeting the requirements of scenarios with high real - time requirements such as video conferences. The wire core specification of this series of terminal wires is 28AWG, supporting a data transmission rate of up to 10 Gbps. The signal attenuation can be controlled at a very low level within a transmission distance of 1 meter.

(II) Power Supply

The multi - core high - current terminal wires of the 1677173 - 1 model from TE Connectivity are used to connect the power module to the key modules. The wire cores are made of high - purity copper, with excellent electrical conductivity and the ability to carry high currents. The connection terminals adopt a plug - and - play design, which is convenient for installation and maintenance, ensures good electrical connection, and avoids power supply anomalies. The rated current of this model of terminal wire can reach 30A and is suitable for a 48V DC power supply system, which can meet the power requirements of each key module of the switch. Its unique terminal structure design can effectively reduce the contact resistance, reduce heat generation, and improve the power transmission efficiency.

IV. Application Effects

1. Performance Improvement

After using the above - mentioned customized terminal wires, the packet loss rate of the switch is reduced by 30%, the network delay is shortened by 20%, and the processing capacity is greatly improved, meeting the high - speed data exchange requirements of the data center.

2. Enhanced Reliability

The terminal wires have high reliability, and the failure rate of the switch has decreased. In one - year continuous operation, the number of failures caused by connection problems has decreased from 5 times per year to less than 1 time, reducing maintenance costs and downtime and improving the operation efficiency.
