CQF935/908 Series
The JDS Uniphase CQF935/908 series laser is
specifically developed for wavelength division
multiplexing (WDM) systems, where it is used
in combination with an external modulator,
such as the LiNbO3-based Mach-Zehnder.
Selected wavelengths comply with ITU
recommendations, both in range (1527.61 to
1610.06 nm) and in channel definition, thus
adhering to the 100 GHz grid (0.8 nm) relative
to a frequency of 193.1 THz (i.e., a wavelength
of 1552.52 nm). It is possible to customize the
wavelength spacing to a 50 GHz grid (0.4 nm).
Each laser's wavelength is accurately measured,
and the laser itself is accompanied by a datasheet
with the laser performance at the temperature T,
where the required wavelength channel is reached.
The CQF935/908 shows high side mode
suppression ratios, very low relative intensity
noise, and small linewidths. It is available in a
standard 14-pin butterfly package equipped with
a polarization maintaining fiber to facilitate
coupling to the modulator, and shows superb
thermal stability.
Key Features
