DESCRIPTION
¡¡¡¡¡¡¡¡OPV2300/2400 series is high broadcast quality video and audio transmission system. OPV2300 products provide one transmission channel that can carry one analog video and two audio streams over one multimode or single mode fiber. OPV2400 are expanded products of two transmission channels (unidirectional or bi-directional). Unidirectional OPV2400 transmits up to two analog video and four audio (2 pairs of stereos), and bidirectional OPV2400 transmits one analog video and two audio (1 pair of stereo) over one multimode or single-mode fiber. By using digital technology, the transmission distance of the whole system is up to 60 Km. OPV2300/2400 series are your ideal and economic choice for high quality fiber optic transmission.
