The Indonesian island of Bali - a hugely popular holiday resort - has gained its first optical fibre link to the rest of the world following completion of a submarine cable connecting it, neighbouring Lombok, Kalimantan and Sulawesi with the main island of Java.
An optical fibre communication system (NRZ coding) is operating at a data rate of 20 Mb/s and a bit-error-rate of 10^-9 (at most one error can occur for every 10^9 bits sent). The receiver is a PIN-photodiode operating at a wavelength of 850 nm. The source is a GaAlAs LED that couples 50 μW optical power into a fibre (fibre loss is 3.5 db/km) with a 50 μm core diameter.
Mexican telecommunications mogul Carlos Slim Helu says the Commonwealth's optical-fibre National Broadband Network seems over-priced at $43 billion and that Government should focus on a mix of technologies that includes fibre, wireless and copper.
