DVI-7345
Quick Start Guide
Introduction
High Performance – The DVI-7345 is an ultra-compact, high performance ber optic extender
that supports SDI, HD-SDI and 3G-SDI extension over a single strand of Single-Mode optical ber 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 ber 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 amplier. Both Tx and Rx use low-prole, metal
cases equipped with rugged locking 75ohm BNC SDI connectors. The locking ST ber connectors are
supplied with twist-locking metal covers to prevent dust buildup inside the ber 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.

Installation Instructions
This product consists of a transmitter unit and receiver unit. These units are interconnected by means
of a single-channel ST optical cable, utilizing 9/125μ Single-Mode ber. For a list of supported SDI
standards and resolutions, please see page 4.
Note: No controls are present on either transmitter or receiver. Before attempting to use
the extender set, please verify that the source functions properly with the display device by
connecting the source and display devices together using a short coaxial cable.
1.) First, remove the locking metal dust covers from the ST ber optic connectors on the Tx and
Rx units. To do this, push in, turn 45˚ counterclockwise, then pull the cover off.
2.) Connect the BNC SDI connector on the transmitter unit to the SDI output port of the signal source.
3.) Each unit has one (1) optical port. Connect an ST-terminated ber optic cable between the
Transmitter Unit and the Receiver Unit.
4.) Connect the BNC SDI connector on the receiver unit to the SDI input port of the destination
device.
5.) Connect the External AC Power Adapters to the power input jack on both Tx and Rx units.
6.) Apply power to the destination device, then apply power to the source device. The signal should
be available for the display or other destination device within a few seconds.
Note: Always install the dust covers on the ST ber connectors when not in use.
