CQF935/808 Series
The JDS Uniphase CQF935/808 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 LiNbO3-based
Mach-Zehnder.
Selected wavelengths comply with ITU recommen-
dations, 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 CQF935/808 shows high side mode suppres-
sion 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
1550 nm WDM distributed feedback laser diode
High power (> 50 mW)
Polarization maintaining fiber
Built-in thermoelectric cooler
Cooled, built-in optical isolator
1527 - 1610 nm wavelength range
0.8 nm (100 GHz) spacing
0.4 nm (50 GHz) spacing optional
Applications
Hybrid fiber-coax (HFC) networks, cable-
television (CATV) networks and metro architec-
tures where high power, low RIN, and narrow
linewidths are required
Long haul for compensation of high-loss passive
or active components

Will external interference cause 2812 to enter an illegal interrupt during operation?
I made a PWM rectifier. When the DC voltage is below 200V, the DSP runs normally. But when the voltage is increased to 250V, the DSP tends to run wild, mostly because it enters an illegal interrupt (I...
