Package and Handling Information

Package Information

Recommended Chemicals for Cleaning/Degreasing

820 nm Miniature Link Products

All transmitters and receivers of the 820 nm Miniature

Link Series are housed in a low-cost, dual-inline package

that is made of high strength, heat resistant, chemically

resistant, and UL 94V-O ﬂame retardant plastic (UL File

#E121562). The transmitters are easily identiﬁed by the

light grey color connector port. The receivers are easily

identiﬁed by the dark grey color connector port. (Black

color for conductive port). The package is designed for

pick and place and wave soldering so it is ideal for high

volume production applications.

Alcohols: methyl, isopropyl, isobutyl.

Aliphatics: hexane, heptane, Other: soap solution, naph-

tha.

Do not use partially halogenated hydrocarbons (such as

1.1.1 trichloroethane), ketones (such as MEK), acetone,

chloroform, ethyl acetate, methylene dichloride, phe-

nol, methylene chloride, or N-methylpyrolldone. Also,

Avago does not recommend the use of cleaners that use

halogenated hydrocarbons because of their potential

environmental harm.

Handling and Design Information

Each part comes with a protective port cap or plug cov-

ering the optics. Note: This plastic or rubber port cap is

made to protect the optical path during assembly. It is

not meant to remain on the part for a long period. These

caps/plugs will vary by port style. 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 often is suﬃcient to remove par-

ticles of dirt; methanol on a cotton swab also works well.

5 MBd Logic Link Design

Maximum distance required = 2000 meters by using

HFBR-14x4Z/24x2Z logic link with 62.5/125 µm ﬁber.

The resistor R1 is the only signiﬁcant element in the drive

circuit (see Figure 2) that limits the current through the

LED, apart from the gate´s output port. Depending

on the actual gate used, the voltage drop on the output

mA for reaching a distance of about 2000 meters.

The curves in Figure 3, Figure 4, and Figure 5 are con-

structed assuming no inline splice or any additional

system loss. Besides ﬁber attenuation, for correct power

budget calculation, make sure you take into account the

eﬀect of bending, humidity, ambient temperature, aging

and other relevant inﬂuences. All these additional losses

reduce the achievable link distance accordingly.

current of about 43 mA.

Page 16 shows the guaranteed HFBR-14x4Z´s optical

output power limit of -16.0 dBm (for driver current of 60

mA) over the entire temperature range.

Figure 10 shows the normalized typical output power.

When the transmitter will be driven with 43 mA the opti-

cal output power is about 0.70 or -1.55 dB lower than at

60 mA.

For calculating the LED´s aging eﬀect, an additional loss

of about 1.5 dB is recognized.

With an assumed ﬁber attenuation of 3.2 dB/km and the

reduced driver current of 43 mA, the minimum optical

output power at ﬁber end is about -24 dBm, which is

equal to the receiver sensitivity over the entire tempera-

ture range.

The following example will illustrate the technique for

selecting the appropriate value of I and R1:

tions. For broad use, no additional eﬀects such as aging

CATHODE

The HFBR-14xxZ ﬁber optic transmitter contains an 820

nm AlGaAs emitter capable of eﬃciently launching opti-

cal power into four diﬀerent optical ﬁber sizes: 50/125

µm, 62.5/125 µm, 100/140 µm, and 200 µm Plastic-Clad

Silica (PCS). This allows the designer ﬂexibility in choos-

ing the ﬁber size. The HFBR-14xxZ is designed to operate

with the Avago Technologies HFBR-24xxZ ﬁber optic

receivers.

NOTES:

The HFBR-14xxZ transmitter’s high coupling eﬃciency

allows the emitter to be driven at low current levels

resulting in low power consumption and increased reli-

ability of the transmitter. The HFBR-14x4Z high power

transmitter 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-

14x2Z 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 connectors create large ﬁxed

losses.

1. PINS 1, 4, 5 AND 8 ARE ELECTRICALLY CONNECTED.

2. PINS 2, 6 AND 7 ARE ELECTRICALLY CONNECTED TO THE HEADER.

Consistent coupling eﬃciency is assured by the double-

lens optical system (Figure 1 on page 9). 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.

For 820 nm Miniature Link transmitters with protection

improved option“P”a Zener diode parallel to the LED was

implemented. Therefore, a higher ESD capability could

be attained.

Note: Parameters “reverse input voltage” and “diode ca-

pacitance” for “HFBR-141xPxZ” transmitters deviate from

the non P-parts.

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.

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

applications requiring low edge jitter or high-speed data

transmission at signal rates of up to 155 MBd. Compo-

nent values for this circuit can be calculated for diﬀerent

LED drive currents using the equations shown as follows.

The circuit used to supply current to the LED transmitter

can signiﬁcantly inﬂuence the optical switching charac-

teristics of the LED. The optical rise/fall times and propa-

gation delays can be improved by using the appropriate

circuit techniques. The LED drive circuit shown in Figure

11 uses frequency compensation to reduce the typical

rise/fall times of the LED and a small pre-bias voltage to

minimize propagation delay diﬀerences that cause pulse-

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. 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.

CAUTION: The small junction sizes inherent to the design of these components increase the components’ susceptibility to damage

from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these compo-

nents to prevent damage and/or degradation which may be induced by ESD.

3. For 200 µm PCS ﬁbers, typical responsivity will be 6 mV/mW. Other parameters will change as well.

4. Pin #2 should be ac coupled to a load 510 Ω. Load capacitance must be less than 5 pF.

5. Measured with a 3 pole Bessel ﬁlter with a 75 MHz, -3 dB bandwidth.

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 di-

ameter 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:
