Cooled built-in optical isolator
The JDS Uniphase CQF975/508 series laser is
specifically developed for dense wavelength
division multiplexing (DWDM) systems, where it
is used in combination with an external modula-
tor, such as a LiNbO
3
-based Mach-Zehnder
modulator.
An integrated wavelength locker stabilizes the
laser’s wavelength. The wavelength locker consists
of two back facet monitor diodes. One diode is
unfiltered for use as a conventional power moni-
tor; the other is filtered to provide wavelength
dependent output.
Selected wavelengths comply with ITU recommen-
dations, both in range (for the C and L band, 1527
to 1610 nm) and in channel definition, thus
adhering to the 50 GHz grid. Each laser’s wave-
length is accurately measured, and the laser itself is
accompanied by a datasheet with the laser perfor-
mance at the temperature T
λ
, where the required
wavelength channel is reached.
The CQF975/508 shows high side mode suppres-
sion ratios, very low relative intensity noise
(RIN), 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.
Applications
Hybrid fiber-coax (HFC) networks, cable-
television (CATV) networks, and in DWDM
metro architectures where low RIN and narrow
linewidths are required
