Overview
IEC 62149-5:2009 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies performance standards for fibre optic transceiver modules used in asynchronous-transfer-mode passive optical network (ATM-PON) systems. These systems are recommended by the International Telecommunication Union (ITU) through ITU-T Recommendation G.983.1. The standard focuses specifically on ATM-PON transceivers that integrate laser diode (LD) drivers and clock and data recovery (CDR) integrated circuits (ICs).
This second edition (2009) updates normative references, corrects letter symbols, and harmonizes table notes with related standards, enhancing clarity and consistency within fibre optic active component performance criteria.
Key Topics
- Performance Specifications: Defines optical and electrical performance parameters for ATM-PON transceiver modules, including transmitter and receiver sections.
- Transceiver Module Description: Covers functional definitions and block diagrams detailing transceiver components such as LD drivers and CDR ICs.
- Classification and Product Definition: Outlines the types and applied forms of transceiver modules for PON systems.
- Testing Procedures: Includes characterization and performance testing guidelines to ensure compliance with operational and reliability criteria.
- Environmental and Safety Standards: Specifies requirements for laser safety, electromagnetic emission, and environmental conditions such as vibration, shock, temperature, and humidity to ensure operational robustness.
- Normative References: Incorporates relevant IEC standards (e.g., IEC 60068 series for environmental testing, IEC 60825-1 for laser safety) essential for proper implementation and testing.
Applications
IEC 62149-5:2009 is critical for manufacturers, designers, and quality assurance professionals working with ATM-PON fibre optic transceivers in telecommunications networks. Its applications include:
