This DVIGear DVI-7346 1x ST 12G-SDI Fiber Optic Extender is an ultra-compact, high performance fiber optic extender that supports SDI, HD-SDI, 3G-SDI and 12G-SDI signal extension over a single strand of Single-Mode optical fiber at distances up to 6.2 miles (~10 km). The extender set consists of an optical transmitter module that converts the SDI signals into light pulses for transmission over an optical fiber cable. An optical receiver module converts the light pulses back to an SDI signal for downstream processing or display on a monitor.
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 transimpedance amplifier (TIA), as well as a limiting amplifier. Both Tx and Rx use low-profile, metal cases equipped with rugged locking 75-ohm 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-7346 the perfect solution for extension of SDI, HD-SDI, 3G-SDI, and 12G-SDI signals over extreme distances in even the most demanding broadcast, studio, and live environments.
