IEC 62148-11:20 09涵盖了调制器集成激光二极管发射机的物理接口规范。本标准的目的是充分规定光发射机的物理要求，使符合本标准的发射机在印刷电路板和任何面板安装要求上都具有机械互换性。这第二版取消并取代了第一版。第一版仅限于14引脚调制器集成激光二极管发射机。第二版已扩展到包括14针泵浦激光器，标题已更改以反映新的范围。 本出版物应与IEC 62148-1:20 02一起阅读。

IEC 62148-11:2009 covers physical interface specification for modulator integrated laser diode transmitters. The object of this standard is to adequately specify the physical requirements of an optical transmitter that will enable mechanical interchangeability of transmitters complying with this standard both at the printed circuit board and for any panel mounting requirement. This second edition cancels and replaces the first edition. The first edition was limited to 14-pin modulator-integrated laser diode transmitters. The second edition has been expanded to include 14-pin pump lasers and the title changed to reflect the new scope.

This publication is to be read in conjunction with IEC 62148-1:2002.
