What is BS EN 62149-2 - Fibre optic active components and devices about?
BS EN 62149 is a series on fibre optic active components and devices. Fibre optic active components and devices are made up of semiconductor materials that actively manipulate electrons to perform the intended function. BS EN 62149-2 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. BS EN 62149-2 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.
A product that has been shown to meet all the requirements of BS EN 62149-2 can be declared as complying with BS EN 62149-2 but should then be controlled by a quality assurance/quality conformance program. Depending on the modulation speeds, sub-categorized specifications are defined. Types A1, A2, A3 and A4 correspond to 1,25 Gbit/s, 2,5 Gbit/s, 4,25 Gbit/s and 10 Gbit/s VCSELs, respectively. Each sub-categorized specification is also defined by separate details depending on the device types, such as specifications for a VCSEL device without a monitor photodiode (case a) and for a VCSEL device with a monitor photodiode (case b).

Why should you use BS EN 62149-2 - Fibre optic active components and devices?
Fibre optic laser devices are used to convert electrical signals into optical signals. This part of IEC 62149 covers the performance specification for 850 nm discrete vertical-cavity surface emitting laser devices in fibre optic telecommunication and optical data transmission applications. BS EN 62149-2 describes test methods that state that initial characterization and qualification shall be undertaken when a building standard has been completed and frozen. Qualification maintenance is carried out using periodic testing programs. Test conditions for all tests, unless otherwise stated, are 25 °C ± 2 °C.
Fibre optic transmitters and transceivers using the laser diode specified in BS EN 62149-2 are class 3R laser or lower class (class 1 or 1M) laser certified under any condition of operation. This includes single fault conditions, whether coupled into a fibre or out of an open bore. Fibre optic transmitters and transceivers using the laser diode specified in BS EN 62149-2 are certified to be in conformance with IEC 60825-1. Laser safety standards and regulations require that the manufacturer of a laser product provide information about the product’s laser, safety features, labelling, use, maintenance, and service. BS EN 62149-2 explicitly define requirements and usage restrictions on the host system necessary to meet these safety certifications. Using BS EN 62149-2 you can understand the performance specification for 850-nm discrete vertical cavity surface emitting laser devices of transverse multimode types used for fibre optic telecommunication and optical data transmission applications.
