1T-CT-770 3G/HD/SD-SDI Over Fiber System is used to send 3G/HD/SD-SDI signals to remote display devices, using a single Fiber Optic cable. The individual components of this 3G/HD/SD-SDI Extender over Fiber product consists of the 1T-CT-771 Transmitter and the 1T-CT-772 Receiver which constitute a system used to transmit 3G/HD/SD-SDI signals at resolutions up to 1080p. SMPTE 424M (3G SDI) protocols are supported as well as SMPTE 292M (HD-SDI) and 259M (SD-SDI) protocols.

The 1T-CT-770 system can achieve distribution distances of up to 30km (18.6 miles) for signals with 1080p resolution and 30km (18.6 miles) for signals using 1.485G infrastructure. Input signals are Re-Clocked which prevents deterioration and allows for reconstitution of the signals at the receiving end so that output signal characteristics are the same as those present on the input signal.
