GeckoFlex 8943RDA-DFR Fiber-Ready SD/HD/3G Reclocking Distribution Amplifier

The GeckoFlex 8943RDA-DFR unit is a reclocking distribution amplifier with two dedicated electrical inputs and seven reclocked electrical outputs (in four output pairs). An optional fiber optic submodule can be installed to provide additional fiber optic inputs and outputs.

The module can distribute HD/3G-SDI or SD-SDI streams, making it ideal for mixed format applications, installations where an upgrade to HD/3G is planned, or a combination of HD/3G, SD, or ASI distribution. The fiber option makes it ideal for receiving signals from distant downlinks or transmitting to remote uplinks.

Key Features

Supports SD/HD/3G-SDI rates up to 1080p
Auto or manual input format selection
Fiber-ready for fiber optic submodule option for receiving or distributing over single-mode fiber
Two dedicated electrical inputs
Seven reclocked electrical outputs (in four output pairs: 3x2 and 1x1)
Configurable input to output mapping
100% DVB ASI compliant
High connectivity input/output density with multiple configurations
Remote control and monitoring via Ethernet frame interface
Input to output mapping: all available inputs can be active at the same time and are configurable to any output pair or available optional fiber optic output (one input per electrical output pair or fiber optic output). Availability of fiber optic inputs and outputs depends on the type of option fiber optic submodule installed

Application

Distributing HD/3G signals or mixed HD/3G and SD format installations
Installations where an SD to HD/3G update is planned
Combining HD/3G, SD, or ASI distribution with a long-distance isolated fiber connection
