Photonic integrated circuits for avionics network access and backbone network interface WDM LAN applications

The SAE AS5659 Wavelength Division Multiplexed (WDM) Local Area Network (LAN) standard defines network access (NAI) and backbone network (BNI) optical interfaces. NAIs and BNIs provide optical connection to and within the backbone network, respectively. The backbone network is comprised of optical network elements (ONEs). ONEs include optical multiplex and optical transport layers. Client adaptation elements (which include electrical signal adaptation, electrical multiplex and optical channel layers) interface to ONEs via NAIs. ONEs interface to one another via BNIs.
