Composants et dispositifs actifs à fibres optiques – Normes de performances – Partie 2: Dispositifs discrets à laser 850 nm à cavité verticale émettant en surface (Edition 2.0)
"This part of IEC 62149 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. 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. 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)."
