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
with crosstalk of <-47dB.
The PD-LD product incorporates low
threshold current, high differential
quantum efficiency MQW(Multiple
Quantum Well) FP semiconductor
lasers
whose typical total opating currents
are less than 30mA. Customers
may also request
DFB lasers.The receiver
section offers an 830MHz bandwidth
PIN TIA component that is ideal
for digital operation at 1.25GB/s. These
receivers deliver typically –23dBm optical
sensitivity at a BER of 10-10 at
OC-24/Gigabit Ethernet operation.
AGC allows for high optical input
power.
PD-LD’s BiDirectional WDM modules
are built to meet the demanding requirements
for optical networking. See
PD-LD’s other FSAN Bidirectional
Module offerings for devices optimized
for 155MB/s and 622MB/s.
These modules comply with the
Class 1 Eye Safety standards as
outlined by CDRH1040.10&11, as
well as IEC825-1 and –2.
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
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. is now offering its next
generation of WDM style BiDirectional
transmitter and receiver modules
operating in the 1310 and
1550nm optical windows. These devices
are designed to simultaneously
transmit and receive over a single
optical fiber at frequencies from 10
to 830 MHz. Dual wavelength bidirectional
modules replace the need
for a single mode fiber coupled
laser
diode, a fiber coupled InGaAs PIN
photodiode, a discreet fiber optic
WDM 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.
