Overview
IEC 62149-5:2020 - "Fibre optic active components and devices - Performance standards - Part 5: ATM‑PON transceivers with LD driver and CDR ICs" is the third edition performance standard for transceiver modules used in ATM‑PON (Asynchronous Transfer Mode Passive Optical Network) systems referenced by ITU‑T Recommendation G.983.1. Published by the IEC in 2020, this edition replaces the 2009 version and updates normative references and clause content (notably removing the previous description of types in Clause 4). The standard focuses on defining measurable performance, interfaces and test requirements to promote interchangeability of fibre optic ATM‑PON transceivers (laser‑diode (LD) driver + clock‑data recovery (CDR) IC implementations).
Key topics
- Scope and product definition
- Performance requirements for ATM‑PON transceiver modules with LD drivers and CDR ICs.
- Functional block diagrams, absolute maximum ratings and functional specifications.
- Electrical and optical characteristics
- Defined transmitter and receiver parameters and interface types (e.g., PECL, LVTTL).
- Tables for electrical/optical characteristics and alarm/shutdown signaling.
- Testing and characterization
- Characterization tests for transmitter and receiver sections.
- Performance testing plans and measurement procedures (optical power, eye pattern, extinction ratio).
- Annexes for specialized tests (e.g., tolerance to reflected optical power; alarm/shutdown logic).
- Environmental and safety requirements
- Environmental testing references (vibration, shock, temperature, humidity).
- Laser safety (IEC 60825‑1) and EMC emission requirements (IEC 61000‑6‑3).
- Normative references
Applications
- Who uses this standard
- Fibre optic transceiver manufacturers designing ATM‑PON modules with LD drivers and CDR ICs.
- Test laboratories and QA teams performing characterization, compliance and interchangeability testing.
- Network equipment vendors, systems integrators and service providers procuring ATM‑PON transceivers.
- Certification bodies assessing product conformity to international performance criteria.
- Practical value
- Ensures consistent, testable performance criteria across suppliers to simplify procurement and interoperability efforts.
- Provides standardized test methods and interface definitions used during design verification and production testing.
