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 450MHz. 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. The receiver
section offers a 450MHz bandwidth
PIN TIA component that is ideal for
digital operation at 622MB/s. These receivers deliver typically –31dBm optical sensitivity at a BER of 10-10 at OC12/STM4 operation. AGC allows for
high optical input power.
PD-LD’s BiDirectional WDM modules
are built to meet the demanding requirements for ATM-PON ONU and
LTU applications. See PD-LD’s other
FSAN and Bidirectional Module offerings for devices optimized for 155MB/
s and 1.25 GB/s.
PD-LD Inc. reserves the right to make modifiations to or discontinue products without prior notice.
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 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.
