Overview
IEC 62148-11:2009 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the physical interface requirements for fibre optic active components, specifically 14-pin active device modules. This part of the IEC 62148 series focuses on modulator integrated laser diode transmitters and 14-pin pump laser modules. It defines mechanical and electrical interface criteria to ensure mechanical interchangeability and compatibility of optical transmitter modules used in fibre optic communication systems.
This second edition builds upon the original 2003 edition by expanding the scope from only modulator integrated laser diode transmitters to also include 14-pin pump lasers. The standard aligns with IEC 62148-1, which provides general guidance for fibre optic active components.
Key Topics
1. Scope and Object
- Defines the physical interface for 14-pin optical transmitter modules.
- Ensures mechanical interchangeability for mounting on printed circuit boards (PCBs) and panels.
- Covers pigtail and electrical interfaces for laser diode transmitters and pump lasers.
2. Electrical Interface
- The standard defines pin numbering and pin function for 14 pins on the module.
- Pins include connections for laser diode anode and cathode, photodiode (PD) monitor, thermistor, thermo-electric cooler (TEC), grounds, and RF data input for modulators.
- The pin configuration supports both modulator integrated laser diode transmitters and pump laser diode devices with clear functional distinctions.
3. Mechanical Dimensions and Footprint
- Specifies detailed mechanical outlines for modules, including maximum and minimum dimensions for case, pin spacing, and mounting holes.
- Provides drawings for modulator integrated laser transmitters and pump lasers with a 14-pin butterfly package design.
- Includes footprint layouts for panel mounting or PCB integration to assist manufacturers and designers in ensuring compatibility.
4. Optical Interface Compatibility
- Supports optical fibres compliant with IEC 60793-2-50 single-mode fibre specifications.
- Compatible with optical connectors following the IEC 60874 series to enable standardized pigtail terminations.
Applications
IEC 62148-11:2009 applies primarily to the telecommunications and data communications industries where reliable, standardized laser transmitter modules are essential. Key applications include:
- Fibre Optic Communication Networks: Ensures consistent mechanical and electrical interface for modulator integrated laser transmitters within high-speed fibre optic transmission equipment.
- Optical Amplifiers: Defines interfaces for pump laser modules used in rare-earth doped fibre amplifiers to boost signal strength.
- Optoelectronic Module Manufacturing: Enables manufacturers to design 14-pin optical modules that conform to international standards, simplifying system integration and replacement.
- PCB and Panel Mounting Systems: Supports modular integration into printed circuit boards and rack-mounted network equipment with guaranteed interchangeability of compliant components.
The standard facilitates system interoperability and helps reduce time to market by providing clear, internationally recognized guidelines for designing and using 14-pin active device modules.
