Overview

ISO 21111-4:2020 - "Road vehicles - In-vehicle Ethernet - Part 4" defines general requirements and test methods for optical gigabit Ethernet components used in automotive networks. The standard targets optical components for gigabit in-vehicle Ethernet (1000BASE-RHC) and sets out mechanical, optical and environmental test procedures to verify component performance. Electrical safety and electromagnetic compatibility (EMC) are explicitly outside its scope.

Key topics and requirements

This part of the ISO 21111 series covers component-level specifications and test methods, including:

1000BASE-RHC components - scope and component classification for optical gigabit links in vehicles.

Header connectors and cable connectors - dimensional criteria, mechanical coding, mating/unmating forces, retention and insertion force, durability (repeated mating), and evaluation after environmental exposure.

POF and POF cable (Polymer Optical Fiber) - requirements for cladding diameter, numerical aperture, attenuation, bending radius, tensile strength, crush, edge impact, static torsion and flame propagation resistance.

Optical channel - electrical and optical characteristics, physical attributes, positions of test points (e.g., TP2, TP3), and system-level performance evaluations such as transmitter/receiver photoelectric conversion characteristics and coupling attenuation.

Environmental and combined tests - high/low storage and operation temperatures, humidity/temperature cycling, vibration, heat shock, specific physical impacts, chemical and noxious gas exposure, dust, drop procedures and combined environmental load sequences.

Test methodology - light source setup, excitation and measurement equipment, harness setup and informative annexes (system power budget, mode filter).

Practical applications

ISO 21111-4 is practical for designing, qualifying and validating optical gigabit components used in automotive Ethernet networks. Typical uses:

Verifying optical connectors, POF cables and harness assemblies for in-vehicle data links.

Establishing supplier acceptance tests and incoming inspection criteria.

Guiding design decisions for durable, automotive-grade optical components that meet environmental and mechanical stressors.

Defining test sequences for component qualification in harsh automotive environments.

Who should use this standard?

Automotive OEMs and system architects specifying in-vehicle Ethernet.

Supplier and manufacturer engineers of optical connectors, POF cables and transceivers.

Test laboratories and quality managers performing compliance and durability testing.

Integration engineers responsible for vehicle network reliability and maintenance planning.
