OVERVIEW

The 7707MT-HD is a VistaLINK
over a fiber optic link, accompanied by four AES audio signals, serial data, and one GPIO signal. Audio
and control signals are embedded into HD, SD, or SDTi video for optical transport. Embedded audio and
control are extracted from the optical signal by a companion receiver module. The 7707MT-HD is
designed to operate with a companion 7707MR-HD receiver, to permit communication over fiber optic
cable with low latency.
Monitoring and control of card status and parameters is provided locally at the card-edge, or remotely via
VistaLINK capability. The optical output is available in an assortment of optical wavelengths,
®
accommodating 1310nm, 1550nm, CWDM, or DWDM transmission schemes. The 7707MT-HD occupies
one card slot and can be housed in either a 1RU frame, which will hold up to three modules, or a 3 RU
frame, which will hold up to 15 modules.
Features
• HD/SD video, AES audio, serial data, and GPIO conveniently presented in a single product.
• Provides embedding of audio and control signals into HD-SDI (SMPTE 292M), SD-SDI (SMPTE
259M-C), or SDTi (SMPTE 305.2M).
• Audio sample rate conversion permits asynchronous input of 32KHz, 44.1KHz, or 48KHz AES, with
up to 24-bit resolution.
• Audio sample rate conversion may be disabled to permit Dolby-E support.
• With sample rate conversion enabled, transport of audio and control signals is independent of video
interruptions other than format change.
• Audio inputs automatically accept balanced or unbalanced AES without configuration.
• Bi-directional serial port accommodates RS-422, RS-232, or RS-485 data.
• Serial data rates up to 153Kb/s with low latency through link.
• Monitoring of input video format, audio group availability, EDH or CRC errors, and optical power.
• Configurable embedding and selectable input video cleaning provide flexibility.
• Comprehensive signal and status monitoring via four-digit card-edge display or VistaLINK
• Optical output wavelengths of 1310nm, 1550nm, and up to sixteen CWDM wavelengths (ITU-T
G.694.2 compliant).
• DWDM wavelengths also available (ITU-T G.694.1 compliant).
• Compatible with multi-mode and single-mode fiber (dual fiber version).
• SC/PC, ST/PC, or FC/PC fiber connector options.
• Fully hot-swappable from front of frame.
• VistaLINK
enabled for remote monitoring and control when installed in 7700FR-C frame with 7700FC
®
VistaLINK Frame Controller.
