OPV2000M SERIES (Analog Video/Audio)

4/8/16 Channel Analog Audio Fiber Optic Transmission System


OPV2000M series can transmit 4/8/16 channels of unidirectional or bidirectional audio signals (stereo). These audio products adopt 24bit digital audio coding technology. The “Plug and Play” design enables easy installation and operation. No electric or optic adjustment is required. OPV2000M products can perform properly under various execrable environments, making them your ideal choice, especially for road monitoring systems (including audio dialog function).

The maximum transmission distance is 50 Km (single mode) and 2 Km (multimode). There are LED indicator lights for analog audio connector (XLR) and optic fiber connector (ST/FC/SC) on the front panel, through which users can easily monitor the status of power-supply, connection and channel operation.

Two versions of OPV2000M audio products are provided for option including 1U case and card-cage.
