IEC 62149-2:2014涵盖了用于光纤通信和光数据传输应用的850 nm横向多模离散垂直腔表面发射激光器（VCSEL）设备的性能规范。性能标准包含产品性能要求的定义，以及一系列测试和测量，其中明确定义了条件、严重程度和通过/失败标准。这些测试旨在“一次”运行- 关“证明任何产品能够满足性能标准要求的依据。本第二版取消并取代了2009年发布的第一版，并构成了技术修订版。与前一版相比，重大的技术变化包括引入了10 Gbit/s 850 nm波长垂直腔面发射la的性能标准。”ser（VCSEL）设备以及删除第A条中的封装图和引脚配置。 4和B.4条中引用VCSEL封装标准IEC 62148-15。 关键词:850 nm分立垂直腔面发射激光器（VCSEL）器件，横向多模类型

IEC 62149-2:2014 covers the performance specification for 850-nm discrete vertical cavity surface emitting laser (VCSEL) devices of transverse multimode types used for fibre optic telecommunication and optical data transmission applications. The performance standard contains a definition of the product performance requirements together with a series of sets of tests and measurements with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run on a "once-off" basis to prove any product's ability to satisfy the performance standard's requirements. 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 include the introduction of the performance standards for 10 Gbit/s 850-nm wavelength, vertical cavity surface emitting laser (VCSEL) devices and the deletion of the package diagrams and pin configurations in Clause A.4 and Clause B.4 by citing the VCSEL package standard IEC 62148-15 instead. Keywords: 850-nm discrete vertical cavity surface emitting laser (VCSEL) devices, transverse multimode types
