cable tray

nounid 163657·updated Oct 4, 2026

A physical infrastructure component — a rigid, open or enclosed channel mounted overhead, underfloor, or along walls — used to route, support, and protect bundles of network, power, and telecommunications cables across a facility. In information security and compliance, cable trays function as a **physical safeguard for transmission media**: by enclosing cable runs in a structured, identifiable pathway, they reduce the risk of unauthorized access, physical tampering, accidental damage, and eavesdropping on unencrypted signals traversing those cables. Standards frameworks (NIST SP 800-53 PE-4, NIST SP 800-171 §3.10.2, ISO/IEC 27001 Control 7.12) enumerate them alongside locked wiring closets, conduit, and wiretap sensors as co-equal controls for protecting cabling infrastructure — making the phrase **compositional** in origin (it describes the physical object) but **used as a recognized term of art** within the physical-protection control family whenever physical access control over transmission media is addressed.

Safeguarding measures applied to system distribution and transmission lines prevent accidental damage, disruption, and physical tampering. Such measures may also be necessary to prevent eavesdropping or the modification of unencrypted transmissions. Safeguarding measures used to control physical access to system distribution and transmission lines include disconnected or locked spare jacks, locked wiring closets, cabling protection with conduit or cable trays, and wiretapping sensors.the sentence this term was read in
