1. OVERVIEW
The 7707MTA-HD is a fiber transmitter that extends one HD or SD digital video signal over a fiber optic
link, accompanied by four AES audio signals, serial data, two GPIs and two GPOs. 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. DVB-ASI signals may also be
transparently passed, but audio, serial data and GPIO functions are disabled. The 7707MTA-HD is
designed to operate with a companion 7707MRA-HD receiver.
Monitoring and control of card status and parameters is provided locally at the card-edge. The 7707MTA-
HD occupies one card slot and can be housed in either a 1RU frame, which will hold up to three modules,
or a 3RU frame, which will hold up to 15 modules.
