Sk. Liaw et al., MULTICHANNEL ADD DROP AND CROSS-CONNECT USING FIBER BRAGG GRATINGS AND OPTICAL SWITCHES/, Electronics Letters, 34(16), 1998, pp. 1601-1603
A dynamically selective wavelength add/drop multiplexer (WADM) and a m
ultiwavelength cross-connect (M-XC) configuration for dense wavelength
division multiplexed networks are proposed. Multiple channels add/dro
p and/or cross-connect can be realised according to the control of the
optical switches and fibre Bragg gratings arrangement. The selective
WADM and M-XC devices could provide more reconfigurable flexibility an
d survivability in WDM networks.
