Description
Overview
GAOTek-DFMC-103 transceivers can simultaneously transmit 1-8 channels of 8-bit digitally encoded broadcast quality video / return or bidirectional data / unidirectional or bidirectional audio / Ethernet / Telephone / Dry contact over one multimode or single-mode optical fiber.
These multiplexers are typically used in applications where the cameras have P/T/Z capabilities.
Plug and Play design ensures the ease of installation and operation. Electronic and optical adjustments are never required. LED indicators are provided for instant monitoring system status. Devices are available for either standalone or rack-mount installation, which is suitable for different working environments.
