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 Hewlett-
Packard 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 transmit-
ter 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 connec-
tors 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.
