Introduction

Fiber optic wavelength switches enable the switching of light beams in time, space, and wavelength, and have many applications in optical networks, including optical communication.

Optical fiber is one of the key components in optical fiber communication systems such as optical computers and optical information processing. In recent years, with the dramatic increase in communication network bandwidth, optical fiber...

Communication systems are constantly evolving towards higher capacity and longer distances, and fiber optic wavelength switches are currently and will be used in next-generation intelligent all-optical network communication.

As one of the key components for non-communication applications, it has been mass-produced and commercialized, and has developed into a high-tech industry.

This document is the general specification for fiber optic wavelength switches, aiming to provide a top-level framework for the development of relevant domestic product specifications and testing methods standards.

Fiber Optics Wavelength Switches Part 1: General Specification

1 Scope

This document specifies the requirements and quality assessment procedures for wavelength switches.

This document applies to fiber optic wavelength switches (generally referring to devices, components, and systems with active or passive characteristics) that possess the following characteristics.

(Hereinafter referred to as "wavelength switch").

---The wavelength switch uses an active driving mechanism, while the optical path is passive, meaning it does not include optical amplification and photoelectric conversion.

---The wavelength switch functions only to switch the route of light and does not have power distribution capabilities. That is, it does not include signal broadcasting functionality.

---The wavelength switch has no fewer than two power transmission ports, and there are no fewer than two routing switching states between the ports.

---The termination type is fiber optic or fiber optic connector.

The wavelength switching specified in this document includes passive optical paths. Except for attenuation, other signal performance requirements are independent of signal type. However, special attention is required.

Note that certain switching and wavelength identification techniques may affect the channel transmission signal; therefore, spatial crosstalk and operating wavelength range need to be considered.

Performance characteristics such as crosstalk and polarization effects.

Wavelength switching typically involves wavelength separation, routing, and multiplexing. Therefore, a wavelength switch may include multiple optical connectors and internal switching components.

For multi-stage switching, this document only specifies the optical performance of the wavelength switching port to port.

This document does not specify the hardware and software for system control and monitoring. Wavelength switching assemblies may contain other functional components (such as fiber optic connectors or...).

Wavelength monitoring), and any resulting degradation in switching performance, are taken into account in the wavelength switching specification.
