Temperature Tunable
10 mW WDM Laser
for Direct Modulation
in Links up to 180 km
CQF413/608 Series
The JDS Uniphase CQF413/608 is a two-channel,
tunable, directly modulated laser source for use
in metro wavelength division multiplexing (WDM)
systems with bit rates of up to 2.5 Gb/s and link
lengths of 180 km. Peak output power is 10 mW.
Wavelengths are available in the 1527.22 to
1610.06 nm range (C and L bands), in accordance
with ITU recommendations. Each laser adheres
to the 100 GHz grid and can be adjusted via
temperture tuning between two adjacent channels
(three channels adhering to the 50 GHz grid).
The CQF413/608 laser is available in a standard
14-pin butterfly package with a single-mode
fiber. It shows excellent thermal stability and
features a built-in cooled optical isolator. The
internal bias-T network and built-in monitor
diode enable simple DC-bias conditioning and
laser diode output power stabilization.
Under small signal modulation conditions,
device bandwidth exceeds 3 GHz. Due to the
intrinsic low chirp characteristic of its distributed
feedback (DFB) laser, the CQF413/608 is especially
suitable for digital transmission at 1550 nm.
Key Features

Applications
•
WDM metro architectures and cable television
(CATV) networks, where high optical output
power and very low dispersion are required.
Especially suitable for systems operating in
environments with uncontrolled ambient
temperature.
•
100 GHz ITU grid system design without
increasing the complexity of inventory compared
to 200 GHz system architectures.
Compliance
•
Fiberoptic pigtail, including connector,
complies with UL94 V-0 flammability rating
