DESCRIPTION
The PLD-1315 and PLD-231X Series are
designed to be backward compatible with
industry standard sources and detectors used
for single mode fiber applications. This form
factor allows designers to offer single mode fiber
performance in applications which currently use
short wavelength (850 nm) devices in identical
form factor packages . A link upgrade from
multimode to single mode fiber can be done as
easily as swapping out the optical components
on the printed circuit board.
TRANSMITTER
The PDL-1315M/TM is constructed using a 1300
nm Edge Emitting LED (ELED) . Such ELED’s
efficiently couple their optical output into single
mode optical fiber. Although a single mode
emitter, driving the ELED can be done with the
same circuitry used with multimode LED based
components. Such circuitry is much simpler than
that used with LASER based emitters given that
no optical feedback is required with an ELED.

Product Data Sheet
RECEIVER
Two semiconductors make up the heart of the
HFBR-231XM/TM receiver modules: a 75 um diameter
InGaAs PIN photodiode and a silicon based
trans-impedance amplifier (TIA). The PIN photodiode
is optimized for high response in the 1300 nm
wavelength region and has been teamed with a low
noise TIA . The optical signals are detected by the
PIN and converted to an analog voltage output with
a very low input noise current contribution. The TIA
is available with or without an Automatic Gain Control
(AGC) circuit that decreases the light to voltage
conversion factor when the average incident optical
power is relatively high. There are three (3) versions
of receivers available;
Transmitter (TX) PLD-1315TM PLD-1315M
Receiver (RX) PLD-231XTM PLD-231XM
Threaded Metal Port Unthreaded Metal Port
„h PLD-2315M/TM: with AGC Package Options
„h PLD-2316M/TM: no AGC and with same pin-out
as the PLD-2315
„h PLD-2317M/TM: no AGC and pin-out compatible
with pcb’s designed for Agilent HFBR-2315
series
All of the receivers have differential output signals,
but may also be operated in a single ended fashion
by tying the negative output pin to ground.
The receiver offers a sensitivity of better than –36
dBm at 100 MHz and with appropriate filtering a
minimum overload value of 0 dBm. This large dynamic
range make it ideal for both long and short
range applications.
