Product Bulletin

40 mW 1550 nm CW DFB

Laser with PM Fiber for

WDM Applications

CQF935/708 Series

The JDS Uniphase CQF935/708 series laser is

specifically developed for wavelength division

multiplexing (WDM) systems, where it is used 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

50 GHz grid (0.4 nm) relative to a frequency of

193.1 THz (i.e., a wavelength of 1552.52 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 CQF935/708 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 polariza-

tion maintaining fiber to facilitate coupling to the

modulator, and shows superb thermal stability.
