Cat 6A STP Field Termination Plug

88TSK01 Series

The 88TSK series holds a US patent for its utility designs, which contribute to its intuitive functionality. With its user-friendly design, the series simplifies the wiring and grounding process, allowing for quick and efficient installation in just two minutes. It supports Modular Plug Terminated Links (MPTL) as short as 0.5 meters, ensuring minimal Near End Crosstalk (NEXT) interference. Furthermore, it also supports MPTL connections as long as 90 meters, showcasing its ability to maintain strong signal strength over longer distances, as indicated by attenuation performance. Made in Taiwan Meets Cat 6a MPTL & Patch Cord Limits in any length 4PPoE Compliant US 10,490,960 B1 Patented
With Strain Relief

88TS52G6ATKBT

The 88TS52G6ATKBT is part of the 88TS52G product family and serves as the flagship model in the series. It features a standard body length that offers a generous grounding area of approximately 10mm. The regular length of the plug body provides an adequate buffer that helps maintain a proper bending radius when installed with cables routed through the ceiling or wall. This ensures good strain relief and promotes a reliable connection when connected to PoE built-in equipment. The proper bending radius and strain relief contribute to the overall stability of the connection, enhancing the reliability of the network infrastructure. The 88TS52G6ATKBT plug excels in performance, demonstrating exceptional results in both Cat 6A Modular Plug Terminated Link (MPTL) and even the more demanding Cat 6A Patch Cord Test Limit, surpassing the required standards with a significant margin. The plug is fully compatible with the IEEE 802.3bt 4PPoE (Power over Ethernet) requirement. It has the capability to efficiently deliver 90W of power from the Power Sourcing Equipment (PSE) to the Powered Device (PD), meeting the power delivery standards mandated by PoE Type 4. At the PD end, it ensures the reception of 71.3W of power, ensuring reliable and consistent power supply for PoE Type 4 devices.
