It provides a comprehensive physical interface specification that ensures mechanical interchangeability and consistent performance of these components across different manufacturers.
Designed to be used alongside IEC 62148-1:2002, this standard details the electrical and optical interface requirements, including pin configurations, connector types, pigtail interface options, and recommended package footprints for printed circuit board (PCB) and panel integrations.
Key keywords: interface specification, transmitter components, receiver components, dual coaxial RF connectors, fibre optic active components, package standards.
Key Topics
-
Scope and Application
IEC 62148-17:2013 covers the physical interface specifications relevant to fibre optic transmitter and receiver components incorporating dual coaxial RF connectors. It complements general guidelines from IEC 62148-1, emphasizing mechanical and electrical standardization for enhanced compatibility.
-
Electrical Interface and Terminal Assignments
The standard defines key electrical terminal functions and numbering for transmitter and receiver modules. Dual coaxial RF connectors are specified to support high-frequency electrical signals, typically using the SMPM (Sub-Miniature Push-On Miniature) connector interface. Pin assignments include laser diode anodes, photodiode inputs, modulator bias, and modulation voltage inputs, ensuring consistent signal routing.
-
Mechanical Package and Footprint
Detailed mechanical drawings specify package outlines and recommend footprint layouts for PCBs. This facilitates accurate mounting and soldering, ensuring interchangeability and simplifying integration into various system designs.
-
Pigtail and Optical Connector Compatibility
All optical fibres compliant with IEC 60793-2-50 and optical connectors defined in IEC 60874-1 are applicable, allowing flexible optical interconnect configurations for diverse applications.
-
Electromagnetic Compatibility (EMC)
The components must meet suitable EMC requirements, including emissions and immunity, under different operational environments. IEC Guide 107 offers guidance on drafting EMC requirements; however, electrostatic discharge (ESD) standards for these devices are still under development.
