TLDR
In this article, a tree-type interconnection of SOLARnets at layer 1 and enlarges the network scale using WDM is used to overcome self-collision (collision of the packet header with its packet).Abstract:
A repeater for the 32 Mbit/s star-configured optical local area network (SOLARnet) has been developed This repeater permits a tree-type interconnection of SOLARnets at layer 1 and enlarges the network scale Wavelength-division multiplexing (WDM) is used to overcome self-collision (collision of the packet header with its packet)read more
