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 \u201conce-off\u201d basis to prove any product\u2019s ability to satisfy the performance standard\u2019s requirements.<\/p>\n<p>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.<\/p>\n<p>Depending on the modulation speeds, subcategorized specifications are defined. Types A1, A2 and A3 correspond to 1,25 Gbit\/s, 2,5 Gbit\/s and 4,25 Gbit\/s VCSELs, respectively.<\/p>\n<p>Each subcategorized 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).<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Fibre optic active components and devices.
