IRT-6690-DDT & IRT-6690-DDR: 8 Channel SD-SDI/ASI Fibre Optic Link

IRT-6690-DDT & IRT-6690-DDR Home Page, PDF Brochure

The IRT-6690-DDT and IRT-6690-DDR is an 8 channel SD-SDI/ASI optical fibre link for point to point transmission using single mode fibre.

FEATURES:

  • 270 Mb/s type signals, such as ASI and SDI, capability.
  • Automatic cable equalisation for up to 300m on each input.
  • Optical path loss ≥ 27dB.
  • DashBoard software monitoring and control.

IRT-6170 Block Diagram

The IRT-6690-DDT accepts up to eight 270 Mb/s input signals which may be ASI, SDI or a mixture of each type. The signals need not be phase or frequency synchronous.

The signals are multiplexed into a single 3G compliant (2.97 Gb/s) and transmitted optically via a single mode fibre. The IRT 6690 DDR receiver performs the reverse operation and restores correct 270 Mb/s timing.

The IRT-6690-DDT/IRT-6690-DDR system is primarily designed for use with a 9/125μm single mode fibre and will allow an optical path loss up to 27dB.

The IRT-6690-DDT transmitter comes standard with a 1310nm DFB laser. Other CWDM wavelengths are available. The IRT 6690 DDR receiver comes standard with an APD detector.

The IRT-6690-DDT & IRT-6690-DDR are designed to fit the openGear standard 2RU frames which allow a mixture of cards from various manufacturers to be mounted within the same frame.

The DashBoard control software is available as a free download.
