Petaluma, California-based Nentronix Corp has launched what it claims is the first local area network that uses both plastic optical fibre and glass to move data. Forecasting a growth in the use of plastics in local nets, the company claims it has overcome a major problem of plastic optical fibre, the limited ability to carry data long distances – Nentronix says the network supports span 500 feet between any two nodes and, where longer distances are needed, the network accommodates glass fibre which can support 6,000-foot distances. It claims that advantages arise from plastic’s toughness, immunity from electrical interference, and the absence of electrical radiation. Running at 2Mbps, the Fiberstar network consists of MSDOS optical fibre local network adaptors and optical fibre hubs, cable, and wall plates and is compatible with Ethernet, StarLan and broadband networks.
