Sk. Liaw et al., Experimental investigation of wavelength-tunable WADM and OXC devices using strain-tunable fiber Bragg gratings, OPT COMMUN, 169(1-6), 1999, pp. 75-80
Two reconfigurable wavelength add/drop multiplexer (WADM) and optical cross
-connect (OXC) devices based on strain-tunable fiber Bragg gratings (ST-FBG
s) are proposed. The feasibility of WADM is verified by measuring the bit-e
rror-rate performance of the dropped (cross-connect) and pass-through (no c
ross-connect) channels over a 50- and 100-km standard single-mode fiber for
a 2.5 Gb/s system. Compared to back-to-back transmission, a negligible pow
er penalty of only 0.2 dB is observed. (C) 1999 Published by Elsevier Scien
