Compatible
links for a wide variety of data
communication applications from
low-speed distance extenders up
to SONET OC-3 signal rates.
Pinouts identical to Agilent
HFBR-0400 Series allow
designers to easily upgrade their
820 nm links for farther distance.
The transmitter and receiver are
compatible with two popular
optical fiber sizes: 50/125
µm
and
62.5/125
µm
diameter. This
allows flexibility in choosing a
fiber size. The 1300 nm wave-
length is in the lower dispersion
and attenuation region of fiber,
and provides longer distance
capabilities than 820 nm LED
technology. Typical distance
capabilities are 2 km at 125 MBd
and 5 km at 32 MBd.
transmitter to the HFBR-1312T
requires only the removal of a few
passive components.
Receiver
The HFBR-2316T receiver con-
tains an InGaAs PIN photodiode
and a low-noise transimpedance
preamplifier that operate in the
1300 nm wavelength region. The
HFBR-2316T receives an optical
signal and converts it to an analog
voltage. The buffered output is an
emitter-follower, with frequency
response from DC to typically 125
MHz. Low-cost external compo-
nents can be used to convert the
analog output to logic compatible
signal levels for a variety of data
formats and data rates. The
Transmitter
The HFBR-1312T fiber optic
transmitter contains a 1300 nm
InGaAsP light emitting diode
capable of efficiently launching
optical power into 50/125
µm
and
62.5/125
µm
diameter fiber.
