Do not power up the unit when there is no fiber attached to the fiber connection port. There are no user adjustments inside the Diamondback. Do not attempt any type of service to this instrument other than so instructed in this manual. Refer servicing to Telecast Fiber Systems, Inc. -
Page 5: Introduction
Configuration diagrams are featured on page 5. Within a DiamondBack TX, the video signals are first digitized at 147 MHz and then multiplexed at a data clock rate of 1.47 Gb/s. This digital data is converted to an optical signal and launched into the fiber. -
Page 6: Attaching The Rack Mount Adapters
Line Power Any power supply used with the DiamondBack must provide a minimum of 1.5 amps, continuous, at 12 to 24 VDC. Although the units will operate at 12 VDC, 13.8 VDC is required to charge the internal UPS battery. -

Telecast Fiber Systems Configuring Signal I/O Rear Panel Connections All setups and connections are on the rear panel, which is the same for the TX and RX units; see Figure 2. Figure 2. Rear Panels, same for TX and RX The rear panel has 8 BNC female connectors. -
Page 8: System Example
DiamondBack input chanelsl switched to “Data” position on the rear panel. An example of an efficient use of the DiamondBack and the Adder 161 is shown in Figure 4. The Adder 161 can multiplex up to 16 channels of audio, 2 streams of digital data, and 4 switch closures for delivery on its coaxial output to the DiamondBack TX. -
Page 9: Fiber Optic Cable Runs
The input at the RX uses a InGaAs pin diode and amplifier to convert the optical signal back into an electrical signal. DiamondBack launches the signals into 9 micron diameter core single mode fibers. Assembled cables and connectors are available from Telecast Fiber Systems, Inc. -
Page 10: Making The Fiber Connection
Diamondback™ The Transmitter’s optical outputs Fiber 1 and Fiber 2 have the following characteristics: • Fully redundant • Have independent power drivers • Both remain active in the absence of a failure The Receiver takes its signal selectively from Fiber 1. If the signal on Fiber 1 is lost, the RX automatically switches to its Fiber 2 input. -
