Rs-232 Fibre Optic Extender
Introduction
A national research organisation is offering a technology for RS-232 fibre optic extender to extend 16 RS-232 serial communication lines beyond the specified distanceof 50 feet. The system comprises two identical units connected to each other with a pair of optical fibres over which 16 Rx and 16 tx signals are transmitted. With the help of the system the distance between Data Communication Equipment (DCE) and Data Terminal Equipment (DTE) can be extended up to one kilometre.

The system is useful where multiple RS-232 supported devices are located away from the computer (DCE). With minor modifications in the design the system can be configured to support 16 digit/I/O lines to transit 16 bit of digital data to remote location. It can be used in a large factories where clusters of numerical controlled machines can be down loaded from the main computer where programme development is done.
- Totally transparent operation.
- All RS-232 baud rates supported.
- Independent and synchronous channel rates.
- Manchester encoding-decoding on multiplexer data communications to reduce the number of fibres to two.
- Indication of channel activities on front panel.
- Multimode graded index fibres with SMA connectors.
- Two identical units to implement the system.
