UTP Feed-Through
Unshielded
Feed-Through Panels serve as ready-to-deploy cross-connect or interconnect between active network switches and structured cabling panels inside TRs.
Unlike traditional punch-down panels, Feed-Through Panels provide immediate plug-and-play convenience: field installers simply plug in pre-terminated, factory-tested patch cords of exact lengths. Once installed, the physical cabling infrastructure remains untouched, allowing IT personnel to easily manage or swap cross-connect cords during routine moves, adds, and changes.
However, despite this convenience, one parameter remains the ultimate performance hurdle: Near-End Crosstalk.
The mating point where an RJ-45 plug engages with a jack creates an instant localized region of impedance mismatch - primary source of NEXT. Placing two RJ-45 jacks back-to-back within the shallow depth of a feed-through coupler requires sophisticated balance design to preserve original signal integrity. Compounding this challenge, patch cords connected to feed-through panels are frequently very short - often just 1 meter on either or both sides. In high-frequency cabling, the shorter the patch cord, the harsher the NEXT penalty, making channel compliance exceptionally difficult.

The HCI SP48KMCA Series solves these signal degradation issues through advanced impedance-matching technology protected under U.S. Patent 9391405 B1.
To eliminate all performance doubts, HCI validates its Feed-Through Panels under the most demanding field test configuration possible: a worst-case 1-meter short patch cord test setup (1m Patch Cord -> Feed-Through Panel -> 1m Equipment Cord) at the TR cross-connect end. Passing this rigorous short-channel certification guarantees complete transmission stability across ISO/IEC 11801 Class Ea, ANSI/TIA-568.2-E Cat 6A, and Cat 6 channel deployments.
