Series Cascade Video Optical Transmission
VOF-N

Node Digital Optical Transmission CCOM VOF-N is designed to transmit signals of long-distance linear distribution. With less fiber cores, the transmission transmits each node signal of a line to the control centers. The products are ideal for use in linear-distribution places like highway etc. to monitor the signal transmission, improve the quality of signal transmission, and substantially reduce transmission costs.
With advanced technology, VOF-N processes all kinds of signals with uncompressed digitalization, and transmits video signals, audio signals and data signals to remote areas with high quality through optical fibers. It can support any high-resolution video signal, is automatically compatible with PAL, NTSC, SECAME and other video formats, and all data formats. It can also transmit video, audio and data signals with multilevel through a 1-core optical fiber.
VOF-N uses digital non-compression technology and WDM technology, forms a chain of network through an optical fiber, and transmits signals of 8-channel video, 8-channel point-to-point data signals and 1-channel shared data signals.

Features

Far-end provides 1-to-4-channel video input, 1-channel point to point RS232/485 data and 1-channel shared RS485 data.

Center-end node machine provides 8-channel video output, 8-channel point to point RS232/485 data and 1-channel shared RS485 data.
