Introdution
The 1700 system provides simultaneous transmission of digital audio, digital video
and/or data over one or one pair of fibers. The 1700 unidirectional system transmits two
(2) AES audios and one (1) SDI video channel in one direction. The 1700
bi-directional system transmits and receives two (2) AES audios and one (1) SDI video
channel in both directions. The video quality in the 1700 system meets SMPTE-259M
specifications and its audio specifications exceed AES3 standards. Many versions of
optical transmitter and receiver combinations are available to address different distance
requirements.
The 1700 features a digital time-multiplexing fiber optic transmission technology,
capable of providing sharp video and crisp audio, with little or no maintenance, high
functionality reliability, and low operating cost. In addition, the audio and video
streams are totally independent. Thus the break of one stream (video or audio) will not
cause the break of the other stream (audio or video). The quality of video, audio and
data transmission in BCI's digital designs is much superior to the embedded video/
audio transmission designs used by other manufacturers. No user adjustments are
required in the 1700 system, enabling quick setup and trouble-free operation.
The 1700 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 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 1700 is capable of addressing a variety of
non-standard configurations. Contact us to discuss your custom, OEM/private brand
and high volume requirements.
