IEC 62148-15:2014 covers the physical dimension and interface specifications for the discrete vertical cavity surface emitting laser (VCSEL) devices in optical telecommunication and optical data transmission applications. The intent of this standard is to adequately specify the physical requirements of VCSEL devices that will enable mechanical interchangeability of laser devices or transmitters complying with this standard both at the printed circuit wiring board and for any panel-mounting requirement. This second edition cancels and replaces the first edition published in 2009 and constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows:
- to include a type-A pin configuration in the 4-pin type VCSEL TO CAN packages;
- to introduce new package standards for high-speed (8 Gbps and 10 Gbps) VCSEL TOSA packages with LC and SC connectors;
- to suggest optional colour codes for various pin configurations and;
- to delete the requirement of the minimum dimension for the outer diameters of the TO CAN packages in order to accommodate recent mini-TO CAN packages. Keywords: discrete vertical cavity surface emitting laser (VCSEL) devices, optical telecommunication and optical data transmission applications
