The overall dimensions of the BIFODEL are determined by the number and dimensions of the switches, and by the minimum bend radius of the fiber pigtails necessary to avoid loss of light between switches.
Both devices are bidirectional but the BIFODEL requires much larger volume.
The optical signals exiting the BIFODELs and the nondelayed path are multiplexed (MUX) and subsequently divided into E channels via an E-channel optical divider.
The BIFODELs use customized piezomechanical 2 x 2 optical switches that have no differential delay between the two switch paths.
