DIN EN 62149-7:2013-02

Fibre optic laser devices are used to convert electrical signals into optical signals. This standard covers the performance specification for 1 310 nm discrete vertical cavity surface emitting laser devices of transverse single-mode and multimode types used for the fibre optic telecommunication and optical data transmission application in a form of the VCSEL chips mounted on a substrate with wire bonding to their chips' anode and cathode terminals without any fibre pigtails. 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 "one-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 a performance standard can be declared as complying with the performance standard, but should then be controlled by a quality assurance/quality conformance program. The responsible committee is Subcommittee DKE/UK 412.2 "Komponenten für Kommunikationskabelanlagen" ("Components for communication cabling systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
