• Abstract:

  IEC 62007-2:2025 specifies measuring methods for characterizing semiconductor optoelectronic devices that are used in the field of fibre optic digital communication systems and subsystems. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Modification of the definition of “optical fibre pigtail” in 3.1.3; b) Correction of an error in Formula (1) for relative intensity noise; c) Correction of an error in Formula (5); d) Correction of errors in the title of Figure 11 and the text of 4.9 (replaced "LD" with "LED"); e) Clarification of how to calculate the 1 dB compression in 4.9; f) Corrections of the circuit diagrams in Figure 2, Figure 5, Figure 11, Figure 17, Figure 18, Figure 19, Figure 20, and Figure 21; g) Clarification of the measurement setup in 5.10 (Figure 28).

Overview

EN IEC 62007-2:2025 (published by CLC/CENELEC, identical to IEC 62007-2:2025) defines standardized measuring methods for characterizing semiconductor optoelectronic devices for fibre optic system applications. This third edition replaces EN 62007-2:2009 and provides a technical revision of test procedures used in R&D, production and qualification of LEDs, laser diodes (LDs), photodiodes (PIN, APD), LD modules and PIN-TIA receiver modules. The standard focuses on laboratory and component-level measurements essential for fibre optic digital communication systems.

Key topics

EN IEC 62007-2:2025 covers measurement requirements and setups for:

• Radiant power and forward current of LEDs and LDs (with or without optical fibre pigtails)
• Small-signal cut-off frequency for emitters and photodiodes
• Threshold current and spectral linewidth of laser diodes
• Relative intensity noise (RIN) and S-parameter characterization for LEDs, LDs and LD modules
• Modulation current at 1 dB compression (LEDs) and calculation clarification for 1 dB compression
• Differential efficiency and differential (forward) resistance of LDs
• Noise measurements for PIN photodiodes and PIN-TIA modules, including minimum detectable power and low-frequency noise corner
• Excess noise factor, multiplication factor of APDs, and responsivity/frequency flatness of PIN-TIA modules

The 2025 edition makes multiple corrections and clarifications (e.g., definition of “optical fibre pigtail”, corrected formulas for RIN, corrected circuit diagrams and clarified measurement setups such as Figure 28).

Practical applications

This standard is essential for:

• Component manufacturers validating device performance and ensuring repeatable test methods
• Test laboratories performing acceptance, qualification and type tests for fibre optic components
• System designers and integrators assessing emitter/receiver characteristics for link budgets, noise analysis and bandwidth planning
• Quality and compliance teams documenting traceable measurement procedures for procurement and regulatory needs

Using EN IEC 62007-2:2025 helps reduce variability in test results, improves interoperability of components in fibre optic systems, and supports reliable product specifications for digital communication subsystems.
