Basic Information
Scope
This document specifies the requirements and quality assessment procedures for wavelength switches.
This document applies to fiber-optic wavelength switches with the following characteristics (commonly referred to as active or passive devices, components, and systems, hereinafter referred to as "wavelength switches").
—— The wavelength switches employ an active driving mechanism, while the optical path is passive, i.e., they do not include optical amplification or photoelectric conversion.
—— The function of the wavelength switches is limited to routing and switching of light, and they do not have power distribution capabilities. This excludes signal broadcasting functions.
—— The wavelength switches have at least two power transmission ports, and the routing switching states between the ports must be at least two.
—— The termination form is fiber optic or fiber optic connectors.
The wavelength switches specified in this document include passive optical paths. Except for attenuation, other signal performance requirements are independent of the signal type. However, particular attention should be paid to the potential impact of certain switching technologies and wavelength identification technologies on channel transmission signals, thus requiring consideration of performance factors such as spatial crosstalk, crosstalk within the operating wavelength range, and polarization effects.
Wavelength switching typically includes wavelength separation, routing selection, and multiplexing. Therefore, wavelength switches may include multiple optical interfaces and multi-level switching within the switch. This document only specifies the optical performance from port to port of the wavelength switches.
This document does not specify the hardware and software for system control and monitoring. Wavelength switch components may contain other functional components (such as fiber optic connectors or wavelength monitori
