The 270/280 features a digital, fiber optic transmission technology, capable of providing sharper video and crisp audio, little or no maintenance, high function reliability, and low operating cost.

The 270/280 system provides simultaneous transmission of digitized stereo audio, video and/or data over one or one pair of fiber. The standard 270 system transmits two (2) audios (or one (1) stereo audio pair) and one (1) baseband NTSC video channel in one direction. The 280 system transmits and receives two (2) audios (or one (1) stereo audio pair), one (1) baseband NTSC video channel, and up to four (4) serial data (RS-232/RS-422) channels in both directions. No user adjustments are required in the 270/280 system, enabling quick setup and trouble-free operation. The 270/280 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 video (BNC), audio (terminal block), and data (DB-9), and fiber connection (FC-type for singlemode fiber or ST-type for multimode fiber). They are also easily monitored by separate LED indicators for power, optical link, and channel activity. Due to its digital transmission design, the 270/280 is capable of addressing a variety of non-standard configurations.
