This part of IEC 62149 covers the performance specification for 1 310-nm discrete vertical
cavity surface emitting laser (VCSEL) 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.
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).
