    • The Weakest Link: Exposing the Dangers of Non-Compliant 8P8C (RJ45) Connectivity
      Feature
      Members
      David Jeskey, Betsy Conroy*The 8-position, 8-contact (8P8C) modular connector, more commonly known as the RJ45, is a highly engineered interconnection system of jacks and plugs with eight equally spaced contacts. Though its history began in the 1960s for telephony, it achieved widespread adoption with the rise of Ethernet networking over twisted-pair cabling.*      15 min
    • Extended-Reach Structured Cabling: Applying Engineered Guidance Beyond the 100-Meter Channel
      Feature
      Members
      Diane Forbes*Structured cabling has long provided the foundation for predictable, interoperable communications infrastructure. For decades, the 100 meter (m) horizontal channel defined by ANSI/TIA-568.1 has balanced performance, power delivery, and administrative simplicity across commercial buildings and campus environments. However, facilities are increasingly requiring connectivity in locations that challenge traditional topology assumptions.*      9 min

    • Structured Cabling—Twisted Pair Shielding: What is Best?
      Feature
      Members
      Gautier HumbertOn the market today, cables for structured cabling exist in various shielded and unshielded types, and it is important to select standard-compliant cables that offer the best performance for individual networks. The discussion is anchored on the principles of noise immunity, shielding types, and the importance of segregation, as outlined in the ISO/IEC series. Through an exploration of how twisted pairs work, the relevance of international standards, and the specifics of shielding and segregation, improved network efficiency and safety can be achieved.      10 min

    • Structured Cabling—Category 7A and Category 7A 22AWG: What are the Advantages?
      Feature
      Members
      Gautier Humbert, RCDDThe ISO/IEC 11801 series are the international standards relevant to structured cabling, and ANSI/TIA 568 series is the North American equivalent, but are there differences? They coordinate together, but Categories 7 and 7A represent a point of disagreement. While they exist in the international documents, they do not exist in the North American equivalent. A thorough history of the categories is necessary to understand the differences and their relevant applications.      14 min
