Laser with PM Fiber for
WDM Applications
CQF935/208 Series
The JDS Uniphase CQF935/208 series laser is
specifically developed for wavelength division
multiplexing (WDM) systems, where it is used as a
wavelength selected source in combination with an
external modulator, such as the LiNbO
3
-based
Mach-Zehnder.
Selected wavelengths comply with ITU
recommendations, both in range (channels from
1527.61 to 1610.06 nm) and in channel definition,
thus adhering to the 100 GHz grid relative to a
frequency of 193.1 THz. Customization of the
wavelength spacing to a 50 GHz grid is possible.
Each laser's wavelength is accurately measured,
and the laser itself is accompanied by a datasheet
with the laser performance at the temperature T
λ
where the required wavelength channel is reached.
The CQF935/208 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.
