Overview
IEC 62148-16:2009 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the physical interface requirements for fibre optic transmitter and receiver components designed to use the LC connector interface. This part of the IEC 62148 series focuses on defining mechanical and electrical specifications that ensure compatibility and interchangeability of these active components at both the printed circuit board (PCB) level and for panel mounting.
This standard is essential for manufacturers and designers in the fibre optic industry who require standardized packaging and interfaces for active optical modules like transmitters and receivers using LC connectors. It supports global interoperability, facilitates streamlined integration into optical systems, and promotes consistency across different vendors.
IEC 62148-16:2009 should be used in conjunction with IEC 62148-1:2002, which covers general package and interface standards for fibre optic active components.
