Increasing demand for network services is driving the introduction of new transmission
formats and channel management technologies that facilitate the efficient use of optical
bandwidth for extremely high data rates.
Whilst the introduction of coherent techniques such as Dual-Polarization Quadrature Phase
Shift Keying (DP-QPSK) enables 100 Gb/s transmission within a 50 GHz channel, traffic with
higher data rates, including 400 Gb/s and 1 Tbit/s signals of the future, are not expected to
fit inside 50 GHz wide channels. These higher data rates require that channel spacings are
flexible and can be increased to allow the use of new transmission formats.
Finisar’s Flexgrid® technology provides dynamic control of the channel center frequency
with 6.25 GHz resolution and channel width with 12.5 GHz resolution within a Wavelength
Selective Switch (WSS), the key element in a Reconfigurable Optical Add/Drop Multiplexer
(ROADM).
Once deployed, channel plans are configurable ‘on-the-fly’, meaning that channel
bandwidths can be adjusted to most efficiently carry future demand as it arises.
Furthermore, as frequency slot edges are aligned to the 12.5 GHz ITU grid, Flexgrid® offers
full backwards compatibility with both the standard 100 GHz and 50 GHz ITU grids, as
illustrated on page 2.
Flexgrid® is available now on all Finisar WSS products.
