Overview
IEC 62007-2:2009 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies measuring methods for semiconductor optoelectronic devices used in fibre optic digital communication systems. This standard focuses on uniform and reliable testing procedures for key optoelectronic components such as light emitting diodes (LEDs), laser diodes (LDs), photodiodes (PDs), and modules integrated into optical networks. The second edition of IEC 62007-2 removes content related to analogue characteristics and harmonizes terminology with related standards in fibre optic communications.
Key Topics
-
Measuring Methods for Optoelectronic Devices:
The standard details procedures to measure important properties of semiconductor devices, including:
- Radiant power and forward current for LEDs and LDs, with or without fibre pigtails
- Small signal cut-off frequency
- Threshold current of laser diodes
- Relative intensity noise (RIN)
- S-parameter (S11) analysis for impedance and reflection characteristics
- Tracking error in LD modules across temperature ranges
- Spectral linewidth assessment
- Modulation current and efficacy compression
- Differential efficiency and resistance
-
Measuring Methods for Receivers:
Methods for evaluating photodetector modules, such as PIN and avalanche photodiodes (APDs), include:
- Noise measurements
- Excess noise factor for APDs
- Frequency response and responsivity
- Output noise power and minimum detectable power
-
Consistent Test Conditions:
To ensure comparability, the standard specifies control of environmental parameters, like device temperature and biasing, during measurements.
-
Equipment and Setup:
Guidance on suitable measuring instruments, system configuration (including integrating spheres, photodetectors, and spectrum analyzers), and calibration procedures is provided for accuracy and repeatability.
Applications
IEC 62007-2:2009 is essential in the design, testing, and validation of optoelectronic devices within:
