Product Usage Instructions

Connecting the Extender:

Connect the DVI-7346-TX unit to the source device using an appropriate cable.
Connect the DVI-7346-RX unit to the display device using another cable.
Connect the ST optical cable between the TX and RX units.
Ensure both units are powered using the provided power adapters or optional USB adapter cable.

Powering the Units:
The TX and RX units can be powered via a USB adapter cable or the supplied external power adapters. Make sure to use the correct power source.

Environmental Considerations:
Place the units in a suitable environment with minimal signal noise for optimal performance.

FAQ:

Q: Can the extender support audio signals?
A: Yes, the extender supports embedded audio channels based on the specific SDI standard.
Q: How far can the extender transmit signals?
A: The standard version supports a certain range, but an extended range version is available on request for longer distances.

Optical fiber transmission is immune to environmental signal noise

High Performance — The DVI-7346 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 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 transimpedance amplifier (TIA), as well as a limited 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.
