PL1625 Isolated DFB Series Laser Diodes

PD
LD

Inc.

PD-LD Inc. offers its’ PL1625 DFB
Series of coaxial style laser diodes with
integral optical isolators. The addition of
these isolators ensures a minimum
optical isolation of 30dB at 1650nm
over the entire operating temperature
range. These lasers may be operated
from –40 to 85°C while maintaining all
of the DFB spectral characteristics.
These units are available in ready-touse, fiber-pigtailed packages and may
be terminated with all standard optical
connector varieties .
The InGaAsP DFB laser diodes
offered by PD-LD are of proven design
and manufacture. The semiconductor
lasers have been qualified as per
Telcordia GR-468. The highly stable
YAG Laser welded packaging ensures
a low tracking error of +/- 1.0 dB
maximum over OTR -40 to 85°C .
These
components
are
in
compliance with RoHS Directives. The
1625nm DFB lasers couple 2mW
optical power into 9/125um SMF and so
are considered Class 1 Eye Safe as
defined by the IEC825-1 & –2 and the
CDRH 1040.10 definitions.
Optional board- or panel -mount
flanges are available for pigtailed
devices; contact PD-LD Sales.
