DESCRIPTION
The DVM-2500 series is a compact standalone unit designed to provide bi-directional video, audio and data transmission
over one strand of single mode fiber.
It is ideally suited to applications such as teleconferencing, distance learning, STL and studio to studio links.
The DVM-2500 series supports NTSC, PAL, SECAM as well as video with diplexed audio carriers at 4.5MHz, 5.8 MHz
and 6.4 MHz (Option for 10 MHz). The design features differential video and audio inputs which greatly reduce hum and
noise. Video and Optical front panel status indicators with dry alarm relay contacts.
