Point to Point Video Optical Terminal

Global Tech GT-VO-1 Series digital non-compressed Video Optical Terminal adopts the lossless digital video coding technology, the digital TDM technology and the high-speed digital optic fiber transmission technology. With the modular design suitable to the integrated transmission requirement for the video/ audio/ data/ Ethernet/ switch signal, GT-VO-1 can transport 1~16 route of video signal, 8~16 route two-direction audio /data/ switch signal or its combination, and 1 route Ethernet signal over one single-mode optical fiber or multi mode optical fiber. With CWDM technology, GT-VO-1 supports up to 64 route video channels over one single-mode fiber. Adopting the high reliable VLSI, Very Large Scale Integrated Circuit, and SMT, Surface Mounting Technology, GT-VO-1 is one of the most advanced transmission products in remote high-resolution real-time video monitoring field.
