1 Scope

GB/T 24366-2024 specifies the photodetector module used at the receiving end of an optical link. It is the component that turns light back into an electrical signal, and it sets the limit on how far a link can reach: the weakest optical power at which the receiver still recovers data determines the span between amplifiers, and every decibel of receiver sensitivity is worth real money over a network. Its performance depends on properties that have to be specified precisely rather than described - responsivity, dark current, bandwidth, and the noise contributed by the detector and by the amplifier packaged with it - because a module a fraction of a decibel worse than specified turns into a link budget that does not close on a route already built. This document defines the terms, definitions and abbreviations for optoelectronic detector modules for communications and specifies their classification, their optoelectronic performance requirements and the associated requirements. Under ICS 33.180.10 and CCS M33, it is written for optical component manufacturers, for the makers of transceivers and line equipment, and for the telecom operators and testing laboratories that verify what they bought.

This document defines the terms, definitions, abbreviations and abbreviations of photoelectric detector assemblies for communications (hereinafter referred to as "detector assemblies"), and specifies the The classification, optoelectronic characteristics, environmental compliance and other technical requirements of device components. This document applies to the design, development, production and use of photodetector components in digital optical communication systems as well as analog optical communication systems. test.
