DESCRIPTION
The DVM-2700 is ideal for applications that require multiple video and audio to be transmitted over one fiber. Applications
include back haul, studio to studio and STL.
The all-digital processing,12 bit video and 24 bit audio, provides superior
performance characteristics.
Advanced CWDM technology allows up to 8 lengths to be put on one strand of fiber.
The DVM-2700 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. A -RMT kit allows unit to be mounted
in a standard 19” equipment rack.
