Overview
IEC 60875-1:2015 is an international standard published by the International Electrotechnical Commission (IEC) that specifies uniform requirements for non-wavelength-selective fibre optic branching devices. These devices are passive components used in fibre optic networks, designed to split or share optical power across three or more ports without wavelength selectivity. This generic specification addresses the optical, mechanical, and environmental properties essential for reliable and standardized implementation.
This sixth edition of the standard replaces the 2010 fifth edition and incorporates key technical updates, including revised terminology and definitions to better categorize bidirectional and non-bidirectional branching devices, and the removal of outdated assessment levels. IEC 60875-1:2015 plays a critical role in ensuring interoperability and performance consistency for fibre optic interconnecting devices worldwide.

Devices are classified by type, style, and variant, considering bi-directionality and design specifics. It includes definitions for bidirectional and non-bidirectional non-wavelength-selective branching devices.
-
Standardization Structure
The document defines a three-level specification system covering interfaces, performance parameters, and reliability to harmonize requirements globally.
-
Design and Construction
It specifies materials, workmanship, and quality assurance practices to maintain durability and consistent performance under typical environmental conditions.
-
Performance Requirements
Optical parameters such as loss, uniformity, and isolation are detailed, alongside mechanical and environmental criteria ensuring robust field deployment.
-
Documentation and Marking
Clear guidelines are provided for symbols, drawings, test data sheets, and mandatory marking of devices and packages, facilitating traceability and user comprehension.
-
Safety and Compliance
Safety considerations and conformity requirements are covered to align with international electrical and telecommunications safety norms.
Applications
IEC 60875-1:2015 is fundamental for manufacturers, suppliers, and network operators involved with fibre optic systems where optical power distribution is required without wavelength dependency. Typical application areas include:
-
Telecommunications Networks
Passive optical branching components used to split optical signals across access networks and fibre-to-the-home (FTTH) deployments.
