The PT-7501 is an ideal and economic solution designed for transmission of multi-rate SDI video, with embedded
audio and metadata over a multi-mode optical fiber cable.
The transmitter module (PT-7501-TX) receives one HD-SDI electrical input, perfectly converts SMPTE 292M,
SMPTE 259M, or DVB-ASI electrical SDI signal to multi-mode optic SDI signals. The receiver module (PT-7501-RX)
receives optical signal from input LC connector, and then perfectly converts it to electrical SDI signal. Both transmitter and
receiver provide equalizing and re-clocking at input unit in order to re-construct the signal for consistent quality. The
PT-7501 is perfect for today’s broadcast applications, including video production, video editing, studio to studio and studio to
CATV head end. In addition, since transmission of content is inherently secure and immune to outside interference, fiber
applications are favored in government, military, and medical environments.
