The FIO-1901 Series are flexible serial digital video to/from fiber optic converters for the Densité frames. The FIO-1901 converters are designed for 3G, HD and SD serial video but also support DVB-ASI. The converters support any data rate within the range of 19.4 Mb/s to 3Gb/s and provide a reclocked serial digital video from 270 Mb/s to 3Gb/s. The FIO-1901 WDM Series allows the carrying of two independent 3G/HD/SD SDI channels onto a single fiber strand. This is done by using two different wavelengths, one at 1310 nm and one at 1550 nm.
