Lexmark 27X0142 MarkNet N8230 Fiber Ethernet Print Server

Fiber optics have greater electromagnetic immunity, eliminating the chance of radio frequency interference in electrically "noisy" environments such as a factory or warehouse. And since fiber optic systems do not radiate electromagnetic signals like copper transmission lines, even sophisticated electronic methods of intercepting information won't work. Install the card in your supported Lexmark device without external boxes or adapters. You get fiber connectivity in a single, easily installable internal card, shipped in configurations that support many Lexmark devices (see specifications), including appropriate adapters and documentation.
