Custom shuffles with examples developed for velocity measurement. They include in the lower example photo a 48 fiber shuffle unit with 4 ribbons of 12 fibers each going to 12 ribbons with 4 fibers each. Each MT connector contains 3 ribbons each. The upper two in the photo are identical 96 fiber shuffles that were installed in one enclosure and laid out similarly to the 48 fiber shuffle.
OIL constructed a shuffle / delay line for a specific customer. Custom hybrid ribbons with both single and multimode fibers within one ribbon and 8 fibers per ribbon were constructed. A series of specific lengths ranging from several hundred meters to 4 meters in length were made and wound as shown into tight permanent coils for stacking in enclosures for this time pulse division application. The specified lengths were all within +/- 1 cm for the generation of precise set of spaced pulses for each input for signal analysis.
Optical InterLinks constructed 6 backplane units with 12 x12 perfect shuffles per each unit fully MT connectorized at the backplane board edge as shown. The 6 backplane units are all stacked in the enclosure shown in the photo as assembled by Reflex Photonics. These units provided 864 point-to-point channels over the 12 line-cards.
