1300 nm Fiber Optic
Transmitter and Receiver
Technical Data
HFBR-1312T Transmitter
HFBR-2316T Receiver
Features
• Low Cost Fiber Optic Link
• Signal Rates over 155
Megabaud
• 1300 nm Wavelength
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
• Link Distances over 5 km
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.
• Dual-in-line Package Panel-
Mountable ST* and SC
Connector Receptacles
• Auto-Insertable and Wave-
Solderable
• Specified with 62.5/125 µm
and 50/125 µm Fiber
• Compatible with HFBR-0400
Series
transmitter to the HFBR-1312T
requires only the removal of a few
passive components.
Receiver
• Receiver also Specified for
SM Cable Spec (9/125 µm)
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
Applications
• Desktop Links for High
Speed LANs
• Distance Extension Links
• Telecom Switch Systems
• TAXlchip® Compatible
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.

Handling and Design
Information
When soldering, it is advisable to
leave the protective cap on the
unit to keep the optics clean.
Good system performance
requires clean port optics and
cable ferrules to avoid obstructing
the optical path. Clean com-
pressed air is often sufficient to
remove particles of dirt; methanol
on a cotton swab also works well.
Package Information
HFBR-0300 Series transmitters
and receivers are housed is a
dual-in-line package made of high
strength, heat resistant, chem-
ically resistant, and UL V-0 flame
retardant plastic. Transmitters are
identified by the brown port
color; receivers have black ports.
The package is auto-insertable
and wave solderable for high
volume production applications.

Panel Mounting
Hardware
When preparing the chassis wall
for panel mounting, use the
mounting template in Figure 2.
When tightening the nut, torque
should not exceed 0.8 N-m
(8.0 in-lb).
Aliphatics (hexane, heptane)
Other (soap solution, naphtha)
The HFBR-4411 kit consists of
100 nuts and 100 washers with
dimensions as shown in Figure 1.
These kits are available from
Agilent or any authorized distrib-
utor. Any standard size nut and
washer will work, provided the
total thickness of the wall, nut,
and washer does not exceed
0.2 inch (5.1mm).
Do not use partially halogenated
hydrocarbons (such as 1.1.1 tri-
chloroethane), ketones (such as
MEK), acetone, chloroform, ethyl
acetate, methylene dichloride,
phenol, methylene chloride, or N-
methylpyrolldone. Also, Agilent
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.

3. Optical power is measured with a large area detector at the end of 1 meter of mode stripped cable, with an ST* precision ceramic
ferrule (MIL-STD-83522/13), which approximates a standard test connector. Average power measurements are made at 12.5 MHz
with a 50% duty cycle drive current of 0 to I
power.

F,peak F,average
F,peak
4. When changing from µW to dBm, the optical power is referenced to 1 mW (1000 µW).
Optical power P(dBm) = 10*log[P(µW)/1000µW].
5. Fiber NA is measured at the end of 2 meters of mode stripped fiber using the far-field pattern. NA is defined as the sine of the half
angle, determined at 5% of the peak intensity point. When using other manufacturer’s fiber cable, results will vary due to differing
NA values and test methods.
6. Overshoot is measured as a percentage of the peak amplitude of the optical waveform to the 100% amplitude level. The 100%
amplitude level is determined at the end of a 40 ns pulse, 50% duty cycle. This will ensure that ringing and other noise sources have
been eliminated.
7. Optical rise and fall times are measured from 10% to 90% with 62.5/125 µm fiber. LED response time with recommended test
circuit (Figure 3) at 25 MHz, 50% duty cycle.

Receiver Notes:
1. 2.0 mm from where leads enter case.
2. The signal output is referred to VCC, and does not reject noise from the VCC power supply. Consequently, the VCC power supply must
be filtered. The recommended power supply is +5 V on VCC for typical usage with +5 V ECL logic. A -5 V power supply on VEE is
used for test purposes to minimize power supply noise.
3. Typical specifications are for operation at TA = 25°C and VCC = +5 VDC
.
4. The test circuit layout should be in accordance with good high frequency circuit design techniques.
5. Measured with a 9-pole “brick wall” low-pass filter [Mini-CircuitsTM, BLP-100*] with -3 dB bandwidth of 100 MHz.
6. -11.0 dBm is the maximum peak input optical power for which pulse-width distortion is less than 1 ns.
7. Electrical bandwidth is the frequency where the responsivity is -3 dB (electrical) below the responsivity measured at 50 MHz.
8. The specifled rise and fall times are referenced to a fast square wave optical source. Rise and fall times measured using an LED
optical source with a 2.0 ns rise and fall time (such as the HFBR-1312T) will be approximately 0.6 ns longer than the specifled rise
and fall times. E.g.: measured tr,f ~ [(specifled tr,f)2 + (test source optical tr,f)2]1/2
9. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.
.
10. Percent overshoot is defined as: ((VPK - V100%)/V100%) x 100% . The overshoot is typically 2% with an input optical rise time ≤ 1.5 ns.
11. The bandwidth*risetime product is typically 0.41 because the HFBR-2316T has a second-order bandwidth limiting characteristic.
