is less than

2 dB for a total dispersion of up to 1800 ps/nm at

1550 nm. Wavelength drift tests have been per-

formed to warrant long term wavelength stability.

Key Features

• 1550 nm (WDM) DFB laser diode

• Temperature tunable over 2 x 100 GHz channels

• 2.5 Gb/s suitable for OC-48 / STM-16

• Built-in cooled optical isolator

• Wavelengths available from 1527 - 1610 nm

(C and L bands)

• 25

electrical impedance matching

• 100 km distance

(1800 ps/nm dispersion at 1550 nm)

• Operation up to 85 °C

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.

The CQF413/408 is a 2 channel tunable (100 GHz

ITU grid) directly modulated laser source for use

in metro WDM systems up to a bit rate of

2.5 Gb/s and 100 km link length. The peak output

power is 10 mW.

Wavelengths are available in the range from

1527.22 to 1610.06 nm(C and L bands) in accor-

dance with the ITU recommendation. Adhering to

the 100 GHz grid each laser can be adjusted

between 2 adjacent channels (3 channels adhering

to the 50 GHz grid) by temperature tuning.

The laser is available in a standard 14-pin butterfly

package with a single-mode fiber. It has excellent

thermal stability (e.g., wavelength drift with case

temperature is much better than 1 pm/°C).

Dependence of the optical isolation on case

temperature is minimized by a cooled isolator.

The internal bias-T network and built-in monitor

diode enable simple DC-bias conditioning and

output power stabilization of the laser diode.

Under small signal modulation conditions, the

bandwidth of the device exceeds 3 GHz. Due to the

intrinsic low chirp characteristic of the DFB laser,

the device is especially suitable for digital transmis-

sion at 1550 nm. Based on standard single-mode

fiber with non-zero dispersion, the maximum
