NOTE When fitted with APD detectors O to 14dB when fitted with PIN detectors The IRT 6638 DDT and IRT 6638 DDR are 8 channel transmit and receive modules designed principally for use as eight serial data fibre optic transmission links on a single fibre for 3G SDI HD SDI or SD SDI applications conforming to SMPTE standards 424M 292M and 259M C using 9 125 um 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 links may be used for ASI transport streams for use with MPEG compressed video streams or other 270 Mb s type data The receivers use APD detectors with signal conditioning and reclocking circuits The data rates are automatically set to match the 3G SDI HD SDI or SD SDI ASI rates dependent on the actual input data rates to the transmitters A PIN detector version is also available for short run applications The transmitter and receiver modules are compatible with IRT s single channel fibre cards for use as eight independent fibre paths starting from or coming to a single location when used in conjunction with an external 8 channel CWDM optical combiner de combiner A DIP switch selectable keep link alive signal is available to maintain optical link operation when no electrical input is present The IRT 6638 DDT and IRT 6638 DDR are designed to fit the openGear standard 2RU fram
