Backplane Connectors – Specialized: 51940-373LF Application Field and Working Principle

The 51940-373LF is a specialized backplane connector designed for high-speed data communication applications such as those found in modern enterprise and telecommunications networks. It features a reliable hourglass type contact structure which uses staggered linear contact points to reduce signal reflection and improve signal integrity. The hourglass type contact structure is also known for its strong connection force and high electrical performance.The 51940-373LF backplane connector is highly suitable for applications with very high signal integrity requirements, such as the large enterprise/telecom switching systems which utilize two-way and multi-pair connections between units. Being compatible with the popular QSFP standard, the 51940-373LF is often used in the construction of high-speed backplanes for telecommunications as well as providing two-way connection capabilities to computer hardware.The 51940-373LF backplane connector is also designed for ruggedized environments. It has an operating temperature range of -40°C to +85°C, and it is resistant to mechanical stress, shock and vibration. The 51940-373LF connector is rated for up to 6000 mating cycles, making it highly reliable.The 51940-373LF backplane connectors support a wide range of high-speed protocols and speeds, such as 10Gbps, 4X SDH, ATM, LAN, and Wireless. It has the capability to manage different baud rates and protocols in a single cable, allowing for flexibility in applications which require different data rates. The 51940-373LF also has two-way configurations, accommodating both transmit and receive signals from two different sources.In order to implement the 51940-373LF backplane connector, a high-speed backplane design and layout are necessary. The backplane design must ensure that all the required high-speed signals from different modules are properly routed to the different connectors. Additionally, the layout of the board must minimize the crosstalk between signals as this can reduce signal integrity which can sometimes lead to data packet errors.When it comes to the working principle of the 51940-373LF backplane connector, the hourglass connector provides a contact force which is two times greater than standard rectangular connectors. This ensures a very strong and reliable connection which is capable of withstanding damage and wear and tear. Additionally, the staggered linear contact points reduce signal reflection while also providing maximum signal integrity.In conclusion, the 51940-373LF backplane connector is a specialized connector used for high-speed data communication in enterprise and telecommunications networks. It is suitable for ruggedized environments and can manage up to 6000 mating cycles. Additionally, its hourglass contact structure allows for an extra-strong connection with minimum signal reflection, allowing for maximum signal integrity.
