As a packet of charge is transferred through a charge transfer device (CTD), the size of the packet is altered owing to effects of incomplete transfer1-2 and noise.

The employment of redundancy coding to reduce bearing indication error is described.

There are times when problems arise in device implementation that appear to be the product of the sheer perversity of the system designer.

A groat deal of work has been done on error-correcting codes for the binary channel. In this paper we consider codes for a channel that can transmit more than two levels.

This paper is concerned with the problem of transmitting binary signals over a noisy channel.

Error-free unrepeatered transmission of 100 channels at 10 Gbit/s is demonstrated over 350 km.

We have used a packaged high-speed Ti:LiNbO(3) directional coupler switch to externally modulate a cw-operated coupled- cleaved-cavity laser oscillating at 1.3micron wavelength.

Error-free operation of a 100GHz-spaced large scale (16 nodes cascaded over a total distance of 600km) optical network system comprising 15 10Gbit/s/channel channels has been reported.

With optimization of detector threshold and a reservoir channel, error-free transmission of 32x2.5 Gb/s DWDM channels is demonstrated over 130 km using semiconductor optical amplifiers.

By optimising the detector threshold and using an optical reservoir channel, error-free transmission of 32×2.5 Gbit/s DWDM channels has been obtained over 125 km of AllWaveTM fibre using semiconduc
