The IRT-6642-DDT & IRT-6642-DDR is a dual 12G/6G/3G/HD/SD-SDI/ASI optical fibre link for point to point transmission using single mode fibre.
With the advent of 4K/UHD television, distribution of higher data rate video signals up to 11.88 Gb/s (12G-SDI) has become necessary which can’t always be achieved via coaxial cable.
The IRT-6642-DDT and IRT-6642-DDR are dual transmit and receive modules designed principally for use as a serial data fibre optic transmission link for 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI or SD-SDI applications conforming to SMPTE standards 2082-1, 2081-1, 424M, 292M and 259M-C using 9/125 μm single mode fibre. This enables the use of space saving fibre optic cable for reliable transmission of digital video signals over lengths greater than can be achieved with coaxial cable.
In addition, the link may be used for ASI transport streams for use with MPEG compressed video streams or other 270 Mb/s type data.
The transmitter uses a dual laser at different wavelengths that are optically combined to a single optical output. Inputs 1 and 2 are independent from each other allowing a mix of signal rates.
The receiver uses a dual PIN detector with signal conditioning and reclocking circuits. The data rates are automatically set to match the 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI or SD SDI/ASI rates dependent on the actual input data rates to the transmitter.
The IRT-6642-DDT and IRT-6642-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.
Remote monitoring is possible via openGear’s DashBoard® control software, which is available as a free download.
NOTE: 1 – 16dB path loss at HD/SD, 15dB at 3G and 12dB at 12G/6G. Fitted with PIN detector.
