IEC 62099 pdf download – Fibre optic wavelength switches — Generic specification
1General1.1 scope
This International Standard applies to fibre optic wavelength switches.The term “fibre opticwavelength switch” can be used to describe a wide range of devices, assemblies and systemsboth active and passive.Therefore, it is necessary to elaborate on the scope and object of thisstandard. This specification is intended to cover those devices and assemblies which have thefollowing attributes.
– While the switch actuation means is by necessity active，the optical paths through the
switch are passive. Thus，neither optical amplification nor opto-electronic conversion isencompassed.
The switch function is restricted to the routing of light rather than intentional power divisionplus routing.Thus, signal broadcast functions are not encompassed.
They have two or more ports for the transmission of optical power and have two or morestates in which power may be routed or blocked between these ports.
The ports are optical fibres or optical fibre connectors.
Wavelength switching normally involves separation of the individual wavelength streams of lightwhich are re-routed and then recombined. Thus,wavelength switches may involve multipleoptical junctions and multiple-stage switching layouts interior to the switch.However，thespecifications relate to the optical performance from port to port of the overall assembly.
System control and monitoring with their related electronics and software are not covered bythis specification. The switch assembly may have optical means to facilitate such functionality(such as optical taps or wavelength monitoring means), but any related degradation in switchperformance should be covered by the overall switch specifications.
This specification deals with switches that incorporate passive optical paths,and， therefore, itmay be assumed that the signal performance, other than through attenuation, is independent ofthe signal format. However, particularly in the case of wavelength switching, some technologiesfor switching and for wavelength discrimination may have an influence on the signals beingcarried on the channels.Some factors that must be considered are: spatial crosstalk,crosstalkin the wavelength domain, and polarization effects.
This standard establishes uniform requirements for the following points:- fibre optic wavelength switch requirements;
-quality assessment procedures.
