HFBR-2316TZ Receiver
1300 nm Fiber Optic Transmitter and Receiver
Data Sheet
Description
Features
The HFBR-1312TZ Transmitter and HFBR-2316TZ Receiver
are designed to provide the most cost-effective 1300 nm
fiber optic links for a wide variety of data communication
applica­tions from low-speed distance extenders up to
SONET OC-3 signal rates. Pinouts identical to Avago HFBR0400Z 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 wave­length
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.
• RoHS-compliant
Transmitter
Applications
The HFBR-1312TZ 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. Converting the interface circuit from
a HFBR-14XXZ 820 nm transmitter to the HFBR-1312TZ
requires only the removal of a few passive components.

Package Information
The HFBR-2316TZ receiver con­tains an InGaAs PIN photodiode and a low-noise transimpedance preamplifier that
operate in the 1300 nm wavelength region. The HFBR2316TZ 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 compo­nents can be used to convert
the analog output to logic compatible signal levels for a
variety of data formats and data rates. The HFBR-2316TZ
is pin compatible with HFBR-24X6Z receivers and can be
used to extend the distance of an existing application by
sub­sti-tuting the HFBR-2316TZ for the HFBR-2416Z.
The transmitter and receiver are housed in a dual-in-line
package made of high strength, heat resistant, chem­
ically resistant, and UL V‑0 flame retardant plastic. The
package is auto-insertable and wave solderable for high
volume production applications.

Note: The “T” in the product numbers indicates a Threaded
ST connector (panel mountable), for both transmitter
and receiver.
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 com­pressed
air is often sufficient to remove particles of dirt; methanol
on a cotton swab also works well.

Panel Mounting Hardware
Recommended Chemicals for Cleaning/Degreasing
The HFBR-4411Z kit consists of 100 nuts and 100 washers
with dimensions as shown in Figure 1. These kits are
available from Avago or any authorized distrib­utor. Any
standard size nut and washer will work, provided the
total thickness of the wall, nut, and washer does not
exceed 0.2 inch (5.1 mm).
Alcohols (methyl, isopropyl, isobutyl)
Aliphatics (hexane, heptane)
Other (soap solution, naphtha)
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).
Do not use partially halogenated hydrocarbons (such as
1.1.1 tri­chloroethane), ketones (such as MEK), acetone,
chloroform, ethyl acetate, methylene dichloride, phenol,
methylene chloride, or N-methylpyrolldone. Also, Avago
does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm.

Notes:
1. Typical data are at TA = 25°C.
2. Thermal resistance is measured with the transmitter coupled to a connector assembly and mounted on a printed circuit board;
ΘJC < ΘJA.
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 IF,peak; IF,average = IF,peak/2. Peak optical power is 3 dB higher than average optical power.
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.

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-1312TZ) 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-2316TZ has a second-order bandwidth limiting characteristic.
