Fiber-optic transceiver

The sel-2815 fiber-optic transceiver provides electrically isolated, noise-free eia-232 communications over distances up to 15 km in harsh physical and rfi/emi environments. The unit plugs directly into DB-9 serial port connectors and requires 50 mW of power, which is obtained from the eia-232 signals. Users plug in the device, and it transmits full-duplex data at the port`s baud rate--up to 40 kbaud. Continuous light pulses are issued, facilitating functional verification with the use of an optical meter. The transceivers are dce/dte switch-selectable, eliminating the need for adapters. They do not require settings, jumpers, or attenuators. Designed to work with ST connectors, the device accepts fiber diameters ranging from 6 to 200 microns.
