The 285 Series is a low-cost and high-performance Digital Fiber Optic Audio and Data Transmission System, providing simultaneous transmission of digitized audio and serial data. The standard 285 system is designed to transmit one (1) audio channel and one (1) serial data (RS-232/ RS-422) channel over one or one pair of multimode or singlemode fiber. Many versions of optical transmitter and receiver combinations are available to address different distance requirements.

The 285 features a digital fiber optic transmission technology, capable of providing crisp audio, little or no maintenance, high functional reliability, and low operating costs. The quality of audio and data transmission in BCI's digital designs is superior to the analog transmission (based on amplitude or frequency modulation) designs by other manufacturers. No user adjustments are required in the 285 system, enabling quick setup and trouble-free operation.

The 285 comes with two packaging options: a rugged, standalone, and compact unit, or a plug-in card for a card cage system. Panel connectors are provided for audio and data (terminal block connector) and fiber connection (ST-type for singlemode and multimode fiber). The 285 can be easily monitored by LED indicators for power, optical link, and audio/data activity. The standalone units are powered by +12 VDC.

Due to its digital transmission design, the 285 is capable of addressing a variety of non-standard configurations. Contact us to discuss your custom, OEM/private brand and high volume requirements.
