Overview
IEC 62149-2:2014 is an international standard published by the International Electrotechnical Commission (IEC) that establishes performance specifications for 850 nm discrete vertical cavity surface emitting laser (VCSEL) devices. This standard specifically addresses transverse multimode VCSELs used in fibre optic telecommunication and optical data transmission systems. It defines a comprehensive set of product performance requirements, along with rigorous testing procedures and pass/fail criteria to ensure device reliability and functionality.
This second edition, published in 2014, updates the original 2009 version by enhancing performance standards to cover 10 Gbit/s data rates for 850-nm VCSELs and streamlining package specifications through reference to IEC 62148-15. The standard serves as a crucial benchmark for manufacturers and users of fibre optic active components, ensuring consistent quality and enabling interoperability in high-speed optical communication networks.
Key Topics
- 850 nm Discrete VCSEL Devices: Specifies device parameters for vertical cavity surface emitting lasers operating at 850 nanometers, a common wavelength for short-reach multimode fibre optic communications.
- Transverse Multimode Types: Focuses on multimode laser devices suitable for transmitting signals over multimode optical fibres used in data center and telecommunications infrastructure.
- Performance Requirements: Includes detailed criteria for absolute limiting ratings, operating environments, functional specifications, and diagrams that define device operation parameters.
- Testing Protocols: Describes characterization testing and performance testing conducted under controlled conditions to verify compliance with the standard. Tests are designed as “once-off” validations of device capability.
- Environmental and Safety Specifications: Covers operational environment constraints, laser safety guidelines, electromagnetic compatibility (EMC), and general safety provisions ensuring robust device deployment.
- Packaging Standards Integration: References IEC 62148-15 for VCSEL packaging, instead of including package diagrams and pin configurations within its own clauses.
- Data Transmission Speeds: Incorporates sub-categorized performance specifications to address different modulation speeds, including a focus on 10 Gbit/s transmission capabilities.
