This part of IEC 62149 contains the performance standard for 850 nm discrete vertical cavity surface emitting laser (VCSEL) devices of transverse multimode type used for the fibre optic telecommunication and optical data transmission application. The performance standard contains defined requirements for the product performance together with a series 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 the product's ability to meet the requirements for the product performance. At DIN and VDE the responsible Subcommittee is UK 412.2 "Komponenten für Kommunikationskabelanlagen" ("Components for communication cabling systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies).
This document has been replaced by: DIN EN 62149-2:2015-03; VDE 0886-149-2:2015-03 .
