1. The controller is a 16-bit microprocessor that communicates using optical fibre cables. 2. High purity silicon tetrachloride is used in the manufacture of optical fibres . 3. Several communications networks, particularly electric cables and optical fibres , were also affected. 4. This configuration is common with twisted pair cable and optical fibre cable. 5. A newly installed submarine optical fibre cable now connects Vanuatu to Fiji. 6. Splicing optical fibres is much more difficult than connecting copper wires. 7. It has its own private optical fibre networks in several cities. 8. Self-phase modulation is an important effect in optical fibre communications systems. 9. It is already exporting optical fibre to Switzerland, Germany, Netherlands and the UK. 10. Field communications are via Optical Fibre , DSL, Wireless or PAPL connections.
