Description
Overview
GAOTek optical media converters can simultaneously transmit 1 to 72 channels of 8-bit digitally encoded broadcast quality video or reverse or bidirectional data or unidirectional or bidirectional audio or Ethernet or Telephone or dry contact over one single mode or multi mode optical fiber. These multiplexers are typically used in applications where the cameras have PTZ capabilities. Plug and Play design ensures the ease of installation and operation. Electronic and optical adjustments are never required. LED indicators are provided for instantly monitoring system status. Devices are available for either standalone or rack-mount installation ,which is suitable for different working environments.
