PD-LD Inc. now offers its next ge neration of Dual Wavelength Laser
Combiner Modules. These devices
are designed to couple light from
two different semiconductor laser
diodes into a single optical fiber output. Single fiber dual wavelength
combiner modules offer the user the
simplicity of using a single device
when configuring equipment that
requires the output of two different
laser wavelengths.. These Combiner
Modules combine two sources in a
single housing thus relieving the
user of having to fusion splice two
discreet lasers along with a coupler
and then squeeze them onto their
PCB.

These small , compact modules require minimal board real estate and
may be specified by combining any
combination of the following three
wavelengths:
• 1310 nm
• 1550 nm
Modules using 1310 and 1550 nm
DFB lasers may be specified . Pulsed
lasers, suitable for OTDR applications
are also available at both 1310 and
1550 nm.
The PD-LD product incorporates
low threshold current, high differential
quantum efficiency MQW Multiple
Quantum Well) FP semiconductor lasers whose typical total operating currents are less than 30 mA. These low
current consuming laser diodes are well
suited for equipment using battery
power sources. Low threshold and
drive currents help to extend operating
duration between battery recharge or
replacement.

PD-LD Inc. reserves the right to make modifiations to or discontinue products without prior notice.

PD-LD’s Combiner modules are
built to meet the demanding requirements of the instrumentation
marketplace. These units are assembled using state of the art YAG
Laser welding processes. This
technique guarantees a semiconductor to optical fiber interface
that remains stable over mechanical and environmental extreme.
Monitor diode to fiber output
tracking error is guarenteed for
less than 1dB over the –20 to
+70C operating temperature range.
The optical semiconductor die are
mounted within hermetically
sealed TO can subassemblies making them impervious to contaminants and moisture.
Combiner modules are built with 1
meter long 9/125/900 um SMF28
fiber optic pigtails. These fibers
may be terminated with most standard fiber optic connectors including FC, SC, ST and LC .
