Technical Data

Transmitters and receivers are

directly compatible with popular

“industry-standard” connectors:

ST, SMA, SC and FC. They are

completely specified with

multiple fiber sizes; including

50/125 µm, 62.5/125 µm, 100/

140 µm, and 200 µm.

µ

The HFBR-0400 Series of compo-

nents is designed to provide cost

effective, high performance fiber

optic communication links for

information systems and

industrial applications with link

distances of up to 4 kilometers.

With the HFBR-24X6, the 125

MHz analog receiver, data rates

of up to 175 megabaud are

attainable.

Complete evaluation kits are

available for ST and SMA product

offerings; including transmitter,

receiver, connectored cable, and

technical literature. In addition,

ST and SMA connectored cables

are available for evaluation.

Each part comes with a protective

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

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 particles of

• Recommended for use in noisy

environments

In addition to the various port

styles available for the HFBR-

0400 series products, there are

also several extra options that

can be ordered. To order an

option, simply place the corre-

sponding option number at the

end of the part number. For

instance, a metal-port option SMA

receiver would be HFBR-2406M.

You can add any number of

options in series at the end of a

part number. Please contact your

local sales office for further

information or browse HP’s fiber

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.

If resistor R in Figure 2 is

70.4 Ω, a forward current I of

48 mA is applied to the HFBR-

14X4 LED transmitter. With I =

48 mA the HFBR-14X4/24X2

logic link is guaranteed to work

with 62.5/125 µm fiber optic

cable over the entire range of 0

flexibility in choosing the fiber

size. The HFBR-14XX is designed

to operate with the Hewlett-

receivers.

Consistent coupling efficiency is

assured by the double-lens optical

system (Figure 1). 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.

The HFBR-14XX transmitter’s

high coupling efficiency allows

the emitter to be driven at low

current levels resulting in low

power consumption and increased

reliability of the transmitter. The

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.

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 components to prevent damage and/or degradation which may be

Figure 11 uses frequency com-

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.

5. Measured at the end of 100/140 µm fiber optic cable with large area detector.

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.

Tests were performed on both SMA an ST products with the conductive port option.

The Port Strength test was designed to address the concerns with hand tightening the SMA connector to the fiber optic port. The limit

is set to a level beyond most reasonable hand fastening loading.

3.HP has previously used an air discharge method to measure ESD; results using this method vary with air temperature and humidity.

The direct contact discharge method is perferred due to better repeatability and conformance with IEC procedures. ESD immunity

measured with the air discharge method is generally higher than with the direct contact discharge method.

Technical Data

This feature aids in maintaining

the integrity of the signal ground

if the chassis is exposed to elec-

trical noise. In addition, when the

metal port is in good electrical

contact with a well-grounded

chassis, the metal port provides

additional EMI shielding from

electrically noisy circuits.

HP recommends that the designer

use separate ground paths for the

signal ground and the conductive

metal port ground in order to

minimize the effects of external

coupled noise on receiver

circuitry. If noise is present on

the system chassis, care should

be taken to electrically isolate the

metal port from the chassis.

The Metal Port Option is available

with SMA, ST, Threaded ST

(panel mount) and FC styled port

transmitters and receivers. The

electrical/optical specifications,

the mechanical dimensions, and

the pinouts of the components

with metal ports are identical to

the standard plastic port

The metal port option for the

HFBR-0400 Series gives

designers the ability to have a

metal connector receptacle with

the familiar HFBR-0400 dual in-

line package (DIP). The metal

port option components have an

internal electrical connection

between the metal port and the

four grounding pins, as shown in

the package outline drawing.

Signal ground is separate from

the four grounding pins to give

the flexibility in connecting the

port to signal or chassis ground.

products.

In the case of ESD, the metal port

option does not alleviate the need

for system recovery procedures.

A 15 kV ESD event entering

through the connector port will

not cause catastrophic failure,

but the metal port does not

guarantee error-free performance

during an ESD event.
