Overview
The IEC 62148-15:2014 standard defines the physical dimensions and interface specifications for discrete vertical cavity surface emitting laser (VCSEL) packages used in fibre optic active components and devices. This international standard focuses on ensuring mechanical compatibility and interchangeability of VCSEL laser devices and transmitters, particularly in optical telecommunication and optical data transmission systems. It updates the previous 2009 edition by integrating new package types, electrical interface configurations, and optional color coding for pins.
Key enhancements include the introduction of:
- Type-A pin configuration for 4-pin VCSEL TO CAN packages
- High-speed VCSEL TOSA packages (8 Gbps and 10 Gbps) with LC and SC connectors
- Removal of minimum outer diameter restrictions to accommodate mini-TO CAN packages
Adhering to IEC 62148-15:2014 guarantees compatibility across printed circuit boards and panel-mounting setups.
Key Topics
- VCSEL Package Types: Specifies various package forms including TO CAN, TOSA with LC or SC connectors, and pigtail packages.
- Electrical Interfaces: Detailed terminal numbering and pin-function assignments for 3-pin and 4-pin configurations supporting high-speed data transmission.
- Optical Interfaces: Standards for optical connectors and pigtail interfaces to ensure seamless integration with fibre optic systems.
- Mechanical Dimensions: Precise physical outlines and dimensions for different VCSEL packages aiding mechanical interchangeability.
- Color Coding: Optional color coding schemes assist in identifying pin configurations for easier installation and maintenance.
- High-Speed Compatibility: Package designs optimized for data rates of 8 Gbps and above, addressing evolving communication needs.
Applications
IEC 62148-15:2014 is essential for manufacturers, system integrators, and designers involved in:
- Optical Telecommunication: Ensuring VCSEL laser assemblies fit industry-standard interfaces and packages for networking equipment.
- Data Transmission: Facilitating high-speed data link modules in data centers, enterprise networks, and optical interconnects.
