Overview
ISO/IEC TR 11801-9910:2020 is a Technical Report from ISO and IEC that addresses the specifications for modular plug terminated link (MPTL) cabling within customer premises. As part of the ISO/IEC 11801 series for generic cabling, this document defines the configurations, performance criteria, and testing methods relevant to MPTLs. It builds upon foundational standards to ensure interoperability and reliable performance in modern ICT infrastructures. The standard specifically covers performance requirements for cabling Classes D, E, EA, F, FA, I, and II, providing essential guidance for manufacturers, designers, and installers working with field-terminated modular plug links.
Key Topics
-
Modular Plug Terminated Link (MPTL) Definition:
An MPTL is a link terminated with a modular plug (free connector) on one end, commonly used in field-terminated cabling scenarios.
-
Cabling Classes Covered:
- Class D
- Class E
- Class EA
- Class F
- Class FA
- Class I
- Class II
-
Performance Specifications:
MPTLs must meet various transmission parameters, as outlined in ISO/IEC 11801-1, including:
- Return loss
- Insertion loss
- Near-end crosstalk (NEXT)
- Power sum NEXT (PS NEXT)
- Attenuation to crosstalk ratio (ACR-N, ACR-F)
- Power sum ACRs (PS ACR-N, PS ACR-F)
- Propagation delay and delay skew
- Alien crosstalk
- Direct current resistance and unbalance
- Coupling attenuation
- Transverse conversion loss (TCL)
- Equal level transverse conversion transfer loss (ELTCTL)
-
Test Methods:
Testing of MPTLs is addressed, referencing ISO/IEC 14763-4 for methodologies. Tests may be executed either in laboratories (reference testing) or in the field (installation performance) using appropriate measurement tools.
Applications
ISO/IEC TR 11801-9910:2020 delivers practical value for several key audiences:
-
Cabling Designers and Installers:
Offers clear guidance for the selection, implementation, and validation of modular plug terminated links to ensure class-specific performance within customer premises.
-
Product Manufacturers:
Ensures products meet international cabling standards, facilitating global market acceptance and interoperability for modular plug terminated cabling systems.
-
Quality Assurance and Systems Integrators:
Provides a framework for performance and compatibility testing, supporting reliable network infrastructure through verification of field installations.
Typical use cases include:
- Deploying networks in office buildings, data centers, educational facilities, or healthcare environments
- Implementing direct connections from horizontal cabling to active devices without using a traditional outlet
- Supporting power over Ethernet (PoE) and high-speed data transmission to endpoint devices
