High Performance — The DVI-7345 is an ultra-compact, high performance fiber optic extender that supports SDI, HD-SDI and 3G-SDI extension over a single strand of Single-Mode optical fiber at distances up to 1.2 miles (~ 2000 meters).  The extender set consists of an optical transmitter module that converts the SDI signals into light pulses for transmission over a single strand of Single-Mode optical fiber cable.  An optical receiver module converts the light pulses back to an SDI signal for downstream processing or display on a monitor.

Superior Design — The transmitter includes an SDI signal EQ, a Laser driver and a laser diode module that uses a single optical wavelength of 1310nm.  The receiver includes an SDI copper cable driver, a photo diode, a TIA, as well as a limited amplifier.  Both Tx and Rx use low-profile, metal cases equipped with rugged locking 75ohm BNC SDI connectors.  The locking ST fiber connectors are supplied with twist-locking metal covers to prevent dust buildup inside the fiber optic connectors.  These features make the DVI-7345 the perfect solution for extension of SDI, HD-SDI, and 3G-SDI signals over extreme distances in even the most demanding broadcast, studio, and live environments.
