Abstract: An optical backplane interconnect comprises a backplane comprising parallel D-fibers (1) that form an optical bus embedded in a plastics substrate (15), which form a coupling with respective parallel D-fibers (23) at an angle .PHI. in a connecting block (21) that is mounted on a card (2). Circuit components on the card are connected by optical fibers (9) to the fibers in the connecting block. The card is held by connections (18, 19), and as the card is pushed into position, coupling means, comprising balls (25, 26) on the connecting block, it self-aligns in groove (27) on the backplane, to set the angle .PHI. between the fibers, to provide a controlled, reliable optical coupling.

Abstract: An optical network includes an erbium-doped silica-based optical fibre having a D-shaped cross-section. The wave-guide carries information signals at 1.53 .mu.m from a signal source and provides amplification to the information signals when pumped by an optical pump source operating at 0.994 .mu.m. Optical signals are tapped from the waveguide by means of evanescent couplers. The waveguide provides amplification to at least partially restore tapping loss to the information signal due to the optical taps. The core of the optical waveguide is chosen to substantially minimize the spot size of signals at the wavelength of the pump source so as to provide preferential extraction of the information signal in order to leave the pump source substantially undisturbed to be able to pump regions of the amplifying waveguide beyond the optical tap.
