Network Communication by Optical Directional Link
MetadataShow full item record
In this article, infrared point-to-point technologies (optical directional links) are discussed which are designed for digital transmissions. Optical directional links (ODLs) are transparent for the SDH/ATM, FDDI-II, Ethernet, and Token Ring protocols. Depending on type, ODL ranges are 300 m, 500 m, 1000 m and 2000 m. Steady and statistical models of ODL are presented as well as the measuring ODL arrangement and the graphs concerning the fluctuations of the received signal.
