OverviewThe 72477-3221LF is a specialized backplane connector designed specifically for the telecommunications industry. It is unique in its ability to provide high-speed, low power operation and efficient signal stacking. This article will discuss the application field and the working principle of the 72477-3221LF.Application FieldThe 72477-3221LF is designed for use in the telecommunications industry, specifically for the backplane interconnects of base stations and antennas. It is well-suited for applications that require high-speed/low power signal integrity and high stackability. The ruggedness of the 72477-3221LF ensures that it can withstand the demanding applications of base station and antenna environments.Due to its small footprint and low profile, the 72477-3221LF is ideal for applications requiring a tight space constraint such as blade servers and mobile network products. Additionally, its high-speed transmission capability and low insertion loss makes it ideal for base stations and antenna interconnects.Working PrincipleThe 72477-3221LF utilizes two signal lock elements in order to ensure the highest levels of signal integrity. The signal lock element utilizes a non-metallic centralized Shim sandwiched between two conductive elements. The Shim contains a voltage peak that is greater than the peak power of the system. When a current passes through the Shim, an oscillating electric field is created around the Shim due to the Lorentz Force equation. The Lorentz Force causes the shim to move up and down and this movement induces a voltage in the system, allowing for the signal to be transmitted at the high speed and low power levels necessary for telecom wiring.The 72477-3221LF also utilizes a stackable design which allows for the coupling of multiple connectors. This allows for greater connectivity and it also lowers the overall cost of the product. The stackable design also helps eliminate signal cross-talk since each signal stack maintains its own integrity, minimizing potential interference from other signal stacks. This allows for increased signal clarity and reliability over challenging telecom environments.ConclusionThe 72477-3221LF is a specialized backplane connector which is designed specifically for the telecommunications industry. It is well suited for applications requiring high-speed/low power signal integrity and high stackability. Its two signal lock elements combined with its stackable design allow for increased signal clarity and reliability. Additionally, the 72477-3221LF’s small profile and low cost make it ideal for applications requiring a tight space constraint. All of these factors make the 72477-3221LF an ideal connector for base station and antenna interconnects in the telecom industry.
