This specification provides guidance for the physical layer of optical networks which use Wavelength Division Multiplexing (WDM), within the SAE AS5659 WDM LAN specifications document family. The physical layer consists of cabling and connectors which provide the optical interconnections between the components and portions of the network. Performance requirements for general link connections- called the physical layer- are described. Specific sets of documents are identified, corresponding to each of several environments, which describe physical layer design, installation, maintenance, and training.
The aerospace industry requires precise standards for avionics system design. This document helps define interoperability requirements within and between optical Wavelength Division Multiplexed (WDM) Local Area Networks (LANs) used in military and aerospace applications.
