PD-LD Inc. is now offering LED
based WDM style BiDirectional
transmitter and receiver modules operating in the 850 and 1310nm optical windows. These devices, part
number PW13ST, are designed to
simultaneously transmit and receive
over a single optical fiber at frequencies from DC to 200MHz. Dual
wavelength bi-directional modules
replace the need for a multimode fiber coupled LEDs, a fiber coupled
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 two way operation
over a single 62.5/125um optical fiber.
The PD-LD product incorporates
high reliability surface emitting
1300nm light emitting diodes (LEDs)
transmitters that have typical operating currents between 50 and 100mA.
The receiver sections offer discreet
Silicon PIN photodiodes of planar
semiconductor design that have dielectric passivation for very low noise performance at 850nm. See the data sheet
for the PW85ST series for the matching bidirectional module. PD-LD’s
BiDirectional WDM modules are built
to meet the demanding requirements of
industrial operating temperature ranges
of –40 to 85°C.

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

.
The PD-LD BiDirectional modules
are 100% tested for conformance
to specification and are of robust
construction. The optical semiconductor die are mounted within hermetically sealed TO can subassemblies making them impervious to
contaminants and moisture. This
construction ensures that the modules will operate over full industrial temperature range .
