port cap or plug covering the
optics. These caps/plugs will vary
by port style. When soldering, it
is advisable to leave the protec-
tive cap on the unit to keep the

5 MBd Logic Link Design
The following example will illus-
trate the technique for selecting
The curves in Figures 3, 4, and 5
are constructed assuming no in-
line splice or any additional
system loss. Should the link
consists of any in-line splices,
these curves can still be used to
calculate link limits provided they
are shifted by the additional
system loss expressed in dB. For
example, Figure 3 indicates that
with 48 mA of transmitter drive
current, a 1.75 km link distance
is achievable with 62.5/125 µm
fiber which has a maximum
attenuation of 4 dB/km. With
2 dB of additional system loss, a
1.25 km link distance is still
achievable.

6. When changing µW to dBm, the optical power is referenced to 1 mW (1000 µW). Optical Power P (dBm) = 10 log P (µW)/ 1000 µW.
7. Pre-bias is recommended if signal rate >10 MBd, see recommended drive circuit in Figure 11.
8. Pins 2, 6, and 7 are welded to the anode header connection to minimize the thermal resistance from junction to ambient. To further reduce the
thermal resistance, the anode trace should be made as large as is consistent with good RF circuit design.
9. 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
specification methods.

Recommended Drive Circuits
The circuit used to supply current
to the LED transmitter can
significantly influence the optical
switching characteristics of the
LED. The optical rise/fall times
and propagation delays can be
improved by using the appro-
priate circuit techniques. The
LED drive circuit shown in
pensation to reduce the typical
rise/fall times of the LED and a
small pre-bias voltage to minimize
propagation delay differences
that cause pulse-width distortion.
The circuit will typically produce
rise/fall times of 3 ns, and a total
jitter including pulse-width dis-
tortion of less than 1 ns. This
circuit is recommended for appli-
cations requiring low edge jitter
or high-speed data transmission
at signal rates of up to 155 MBd.
Component values for this circuit
can be calculated for different
LED drive currents using the
equations shown below. For
additional details about LED
drive circuits, the reader is
encouraged to read Avago

6. Propagation delay through the system is the result of several sequentially-occurring phenomena. Consequently it is a combination of data-rate-
limiting effects and of transmission-time effects. Because of this, the data-rate limit of the system must be described in terms of time differentials
between delays imposed on falling and rising edges.
7. As the cable length is increased, the propagation delays increase at 5 ns per meter of length. Data rate, as limited by pulse width distortion, is not
affected by increasing cable length if the optical power level at the receiver is maintained.

Notes:
1. 2.0 mm from where leads enter case.
2. Typical specifications are for operation at T = 25°C and V = +5 V dc.

CC
3. For 200 µm HCS fibers, typical responsivity will be 6 mV/ µW. Other parameters will change as well.
4. Pin # 2 should be ac coupled to a load ≥510 ohm. Load capacitance must be less than 5 pF.
5. Measured with a 3 pole Bessel filter with a 75 MHz, -3 dB bandwidth. Recommended receiver filters for various bandwidths are provided in
Application Bulletin 78.
6. Overdrive is defined at PWD = 2.5 ns.
7. D is the effective diameter of the detector image on the plane of the fiber face. The numerical value is the product of the actual detector diameter
and the lens magnification.
8. Measured with a 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.
9. Percent overshoot is defined as:
V
- V
PK 100%
––––––––––
x 100%
(

)
10. The conversion factor for the rise time to bandwidth is 0.41 since the HFBR-24X6 has a second order bandwidth limiting characteristic.
