This DVIGear DVI-7345-Tx 1x ST 3G-SDI Fiber Optic Transmitter that converts the SDI signals into light pulses for transmission over a single strand of Single-Mode optical fiber cable
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.
