IEC 62148-16:2009 covers physical interface specification of transmitter and receiver components for use with LC connector interface. The intent of this part of IEC 62148 is to adequately specify the physical requirements of an optical transmitter and receiver that will enable mechanical interchangeability of transmitters and receivers complying with this standard both at the PCB and for any panel-mounting requirement.
This publication is to be read in conjunction with IEC 62148-1:2002.
