LD Inc
These small , compact modules require
minimal board real estate and
when used in pairs deliver full duplex
operation of a single 9/125um optical
fiber. The use of high performance optical
filters maintains an optical cross
talk between the channels <-24dB.
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 30mA. The receiver
section offers a discreet 75um diameter
InGaAs PIN photodiode of planar
semiconductor design that has diele ctric
passivation for very low noise performance.
(Modules with PIN TIA receiver
sections are also available in a
variety of standard bandwidths).
PD-LD’s BiDirectional WDM modules
are built to meet the demanding requirements
for ATM-PON ONU and
LTU applications.
These units combine the electro
optic performance and robust mechanical
integrity necessary to
meet the demands of passive optical
networks outlined in FSAN,
ITU-G1983.
The PD-LD BiDirectional modules
are assembled using
laser welding
processes. This technique guarantees
a semiconductor to optical fiber
interface that remains stable
over mechanical and environmental
extremes. The optical
semiconductor die are mounted
within hermetically sealed TO can
subassemblies making them impervious
to contaminants and
moisture.
WDM BiDirectional 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.
PD-LD Inc. offers its next generation
of Single Wavelength BiDirectional
transmitter and receiver modules
operating in the 1310 or the
1550nm optical windows. These devices
are designed to simultaneously
transmit and receive over a single
optical fiber at frequencies from DC
to 1.5 GHz. Single wavelength bidirectional
modules replace the need
for a single mode fiber coupled
laser
diode, a fiber coupled InGaAs PIN
photodiode, a discreet fiber optic
coupler and a second stage optical
isolator. The BiDirectional Modules
combine all of these optical functions
and relieve the user of having
to fusion splice several discreet
units together and then squeeze
them onto their PCB.
