DESCRIPTION
The DVM-2000 series is designed for applications that demand high quality video (12 bit), audio (24 bit) and data transmission over fiber.
Applications include links from studio to transmitter (STL), studio to studio, studio to CATV head-end, common carrier, RBOC Telco
circuits, distance learning, Intelligent Transportation Systems & back-haul feeds from special events. This series supports NTSC, PAL,
SECAM as wel
l 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 that greatly reduce hum and noise.
The DVM-2000 is a compact unit designed for stand alone, wall mount or rack-mount applications, while the DVM-2200 modular card plugs
into one of our UTIL-200-DVM series card trays for high density rack mounting. The DVM-2200 with -SDI IN and -SDI OUT options
supports analog video and audio or SDI with embedded audio. The analog video and audio do not operate while in the SDI mode.
The UTIL-200-DVM card tray can also accommodate cards for other formats such as SDI, analog/AES digital audio and reclocking for
maximum flexibility. Advanced CWDM technology is available which enables up to 8 units to be put on one strand of fiber.
