Overview
IEC 62255-3-1:2005 is an International Electrotechnical Commission (IEC) standard that focuses on the framework for detail specifications of multicore and symmetrical pair/quad filled cables. These cables are designed for broadband digital communications, specifically for high bit rate digital access telecommunication networks in outside plant environments. This standard serves as a blank detail specification, providing the structure and key content elements required for preparing comprehensive detail specifications. National organizations, manufacturers, or users can utilize this framework to develop specifications for filled cables used in high-speed telecom infrastructure.
Key Topics
-
Specification Layout and Guidance:
IEC 62255-3-1 defines the required layout, essential details, and correct style for drafting specifications for filled cables. It ensures all necessary technical and functional cable characteristics are comprehensively documented.
-
Scope of Application:
The standard is relevant to multicore and symmetrical pair/quad cables, emphasizing their use in broadband digital access and outdoor telecommunication networks.
-
Preparation of Detail Specification:
Guidance covers what data should be included:
- Descriptions of cable types, construction, and performance
- Details about materials, operating environments, and identifying characteristics
-
Comprehensive Cable Characteristics:
The framework addresses:
- Electrical features (e.g., impedance, resistance, capacitance)
- Transmission performance (e.g., attenuation, crosstalk)
- Mechanical and dimensional points (e.g., strength, bending radius)
- Environmental factors (e.g., temperature range, UV resistance, water penetration)
-
Use of Standardized References:
The document should be read in conjunction with IEC 62255-1 (Generic specification) and IEC 62255-3 (Sectional specification for filled cables), ensuring harmonized application and alignment with broader IEC requirements.
Applications
