Class 1 Eye Safe Device
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.
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 operating 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.
PD-LD Inc. reserves the right to make modifiations to or discontinue products without prior notice.
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.
