HFBR-14x2/14x4 Low-Cost High-
Speed Transmitters
Description
The HFBR-14xx fiber optic
transmitter contains an 820 nm
AlGaAs emitter capable of
efficiently launching optical
power into four different optical
fiber sizes: 50/125 µm, 62.5/125
µm, 100/140 µm, and 200 µm
HCS®. This allows the designer
flexibility in choosing the fiber
size. The HFBR-14xx is designed
to operate with the Agilent
HFBR-24xx fiber optic receivers.
The HFBR-14xx transmitter’s
high coupling efficiency allows
the emitter to be driven at low
current levels resulting in low
power consumption and
increased reliability of the
transmitter. The HFBR-14x4
high power transmitter is
optimized for small size fiber
and typically can launch -15.8
dBm optical power at 60 mA

into 50/125 µm fiber and -12
dBm into 62.5/125 µm fiber. The
HFBR-14x2 standard
transmitter typically can launch
-12 dBm of optical power at 60
mA into 100/140 µm fiber cable.
It is ideal for large size fiber
such as 100/140 µm. The high
launched optical power level is
useful for systems where star
couplers, taps, or inline
connectors create large fixed
losses.
Consistent coupling efficiency is
assured by the double-lens
optical system (Figure 1). Power
coupled into any of the three
fiber types varies less than 5 dB
from part to part at a given drive
current and temperature.
Consistent coupling efficiency
reduces receiver dynamic range
requirements which allows for
longer link lengths.
