8-channel video+2-channel Gigabit Ethernet video optical transceiver-Fornitore globale

product description

8-channel video+1000M Ethernet optical transmitter/receiver adopts digital encoding technology, which can convert 8-channel video signals and 2-channel 10/100/1000ba signalsThe Se-T twisted pair signal, data signal, audio signal, and switch signal are transmitted bidirectionally over long distances through a single-mode optical fiber. The professional design makes it compatible with various control systems such as Philips, AD, Vicon, Pelco, etc. The optical module and core circuit of the video multiplex optical transmitter/receiver are all made of imported components, with high stability. All optical and electrical interfaces are international standards, and can be installed without adjustment, suitable for different working environments.
