CWDM 1.3~1.6um Band Laser Diode Modules
PD-LD Inc. offers a complete
selection of CWDM DFB Lasers for
the O+E+S+C+L+B regions. These
units are available in ready-to-use,
fiber-coupled packages, including
FC, ST, and SC receptacles, as well
as fiber- pigtailed units.
The InGaAsP laser diodes
offered by PD-LD are of proven
design and manufacture; the
standard wavelengths are centered
at 1310, 1330, 1350, 1370, 1390,
1410, 1430, 1450, 1470, 1490,
1510, 1530, 1550, 1570, 1590 and
1 6 1 0 nm. Fiber-coupled CW
(continuous -wavelength) output
powers range from 0.1 - 2 mW,
depending on the fiber type and
desired performance level. Tracking
error over OTR -40 to +85C is +/-
1.0 dB maximum .
The introduction by leading
optical fiber manufacturers of new
fiber varieties suited for operations
from 1310 to 1610nm require the
use of the complete spectrum of
CWDM lasers. Using these new
fibers with PD-LD’s offering of all 16
CWDM wavelengths provides 50%
more spectrum than previously
available. The elimination of the
water peak at 1390nm now makes
possible the use of all 16
wavelengths in these new fibers for
optimum performance in local/
access metro networks. PD-LD’s
lasers are excellent sources for
cost effective coarse wave division
multiplexing, using directly
modulated lasers and relaxing
stringent DWDM filter specifications,
which reduce the overall system
cost.
PD-LD’s CWDM lasers are suitable
for both digital and analog
modulation . The intrinsically fast
rise and fall time of 150psec allow
them to be used in digital
applications require data rates of
3.125GB/s or in analog schemes
which must operate at 3GHz.

The standard lasers are specified
for a center wavelength tolerance of
+/-3nm at 25 degrees C. These
DFB lasers have a wavelength tem-
perature coefficient of 0.10nm/
degree C.
PD-LD coaxially fiber pigtailed laser
diodes are assembled using X-Y-Z ac-
tive alignment to ensure consistent opti-
cal coupling efficiency. Each module is
constructed using at least 18 laser weld
points so that mechanical stability is
precisely maintained. Using this assem-
bly approach guarantees that fiber to
chip alignment is constant despite
changes in ambient temperature from –
40 to +85 C.
Fiber pigtailed modules are available
with all industry style connectors: FC,
SC, ST, LC in both PC and APC pol-
ish. Special connectors are also avail-
able upon request
.
Optional board- or panel -mount
flanges are available for pigtailed
devices; contact PD-LD Sales.
Also, PD-LD Inc. will package
these lasers with optical isolators if
desired. Isolation is typically 45dB
at 25C, and 20dB min over –40 to
85C. PD-LD assemblies are built
using an active micro-positioning
system and laser welding process
ensuring a reliable and well con-
structed product.
PD-LD offers two popular pin-
outs for DFB lasers to address
various existing PCB layouts
