The 125 MBd transceiver is a
cost-effective fiber-optic solution
for transmission of 125 MBd data
up to 100 meters with HCS®
fiber. The data link consists of a
650 nm visible, red LED transmitter and a PIN/preamp receiver.
These can be used with low-cost
plastic or hard clad silica fiber.
One millimeter diameter plastic
fiber provides the lowest cost
solution for distances under 25
meters. The lower attenuation of
HCS® fiber allows data transmission over longer distance. These
components can be used for high
speed data links without the
problems common with copper
wire solutions.
Applications
• Intra-System Links: Boardto-Board, Rack-to-Rack
• High Voltage Isolation
• Telecommunications
Switching Systems
• Computer-to-Peripheral Data
Links, PC Bus Extension
• Industrial Control Networks
• Proprietary LANs
• Digitized Video
• Medical Instruments
• Immune to Lightning and
Voltage Transients
The transmitter is a high power
650 nm LED. Both transmitter
and receiver are molded in one
housing which is compatible with
the FO7 connector. This connector is designed to efficiently
couple the power into POF or
HCS® fiber.
With the recommended drive
circuit, the LED operates at
speeds from 1-125 MBd. The
analog high bandwidth receiver
contains a PIN photodiode and
internal transimpedance
amplifier. With the recommended
application circuit for 125 MBd
operation, the performance of the
complete data link is specified for
0-25 meters with plastic fiber. A
wide variety of other digitizing
circuits can be combined with the
HFBR-5527 Series to optimize
performance and cost at higher or
lower data rates.
HCS® is a registered trademark of Spectran Corporation.

Notes:
1. If the output of U4C in Figure 1, page 4 is transmitted via coaxial cable, terminate with a 50 Ω resistor to VCC - 2 V.
2. Run length limited code with maximum run length of 10 µs.
3. Minimum link performance is projected based on the worst case specifications of the transmitter, receiver, and POF cable, and the
typical performance of other components (e.g., logic gates, transistors, resistors, capacitors, quantizer, HCS cable).
4. Typical performance is at 25°C, 125 MBd, and is measured with typical values of all circuit components.
5. Standard cable is HFBR-RXXYYY plastic optical fiber, with a maximum attenuation of 0.24 dB/m at 650 nm and NA = 0.5.
Extra low loss cable is HFBR-EXXYYY plastic optical fiber, with a maximum attenuation of 0.19 dB/m at 650 nm and NA = 0.5.
HCS cable is HFBR-H/VXXYYY glass optical fiber, with a maximum attenuation of 10 dB/km at 650 nm and NA = 0.37.
6. Optical Power Budget is the difference between the transmitter output power and the receiver sensitivity, measured after
1 meter of fiber. The minimum OPB is based on the limits of optical component performance over temperature, process, and
recommended power supply variation.
7. The Optical Power Margin is the available OPB after including the effects of attenuation and modal dispersion for the minimum
link distance: OPM = OPB - (attenuation power loss + modal dispersion power penalty). The minimum OPM is the margin
available for long term LED LOP degradation and additional fixed passive losses (such as in-line connectors) in addition to the
minimum specified distance.

Notes:
1. Average optical power is measured with an average power meter at 50% duty cycle, after 1 meter of fiber.
2. To allow the LED to switch at high speeds, the recommended drive circuit modulates LED light output between two non-zero power
levels. The modulated (useful) power is the difference between the high and low level of light output power (transmitted) or input
power (received), which can be measured with an average power meter as a function of duty cycle (see Figure 3). Average Modulated
Power is defined as one half the slope of the average power versus duty cycle:
[Pavg @ 80% duty cycle - Pavg @ 20% duty cycle]
Average Modulated Power = ––——————————————————————
(2) [0.80 - 0.20]
3. High and low level LED currents refer to the current through the LED. The low level LED “off” current, sometimes referred to as
“hold-on” current, is prebias supplied to the LED during the off state to facilitate fast switching speeds.

Description
The HFBR-5527 incorporates a
650 nm LED, a PIN photodiode,
and transimpedance preamplifier.
The 650 nm LED is suitable for
use with current peaking to
decrease optical response time
and can be used with the PIN
preamplifier to build an optical
transceiver that can be operated
at signaling rates from 1 to 125
MBd over POF or HCS® fiber. The
receivers convert a received
optical signal to an analog output
voltage. Follow-on circuitry can
optimize link performance for a
variety of distance and data rate
requirements. Electrical
bandwidth greater than 65 MHz
allows design of high speed data
links with plastic or hard clad
silica optical fiber.

5. Optical rise and fall times can be reduced with the appropriate driver circuit.
6. Pins 9 and 10 are primarily for mounting and retaining purposes, but are electrically connected with conductive housing; pins 5 and 6
are electrically unconnected. It is recommended that pins 5, 6, 9, and 10 all be connected to Rx ground to reduce coupling of
electrical noise.
7. Refer to the Versatile Link Family Fiber Optic Cable and Connectors Technical Data Sheet for cable connector options for 1 mm
plastic optical fiber and 200 µm HCS fiber.
8. The LED current peaking necessary for high frequency circuit design contributes to electromagnetic interference (EMI). Care must be
taken in circuit board layout to minimize emissions for compliance with governmental EMI emissions regulations.

Notes:
1. 1.6 mm below seating plane.
2. The signal output is an emitter follower, which does not reject noise in the power supply. The power supply must be filtered as in
Figure 9.
3. Typical data are at 25°C and VCC = +5 Vdc.
4. Pin 1 should be ac coupled to a load ≥ 510 Ω with load capacitance less than 5 pF.
5. Measured with a 3 pole Bessel filter with a 75 MHz, -3 dB bandwidth. No modulation appled to Tx.
6. The maximum Peak Input Optical Power is the level at which the Pulse Width Distortion is guaranteed to be less than the PWD listed
under Test Condition. PR,Max is given for PWD = 5 ns for designing links at ≤ 50 MBd operation, and also for PWD = 2 ns for
designing links up to 125 MBd (for both POF and HCS input conditions).
7. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.
8. Percent overshoot is defined at:
(VPK - V100%)
–––––––––––– × 100%
V100%
9. Pins 9 and 10 are primarily for mounting and retaining purposes, but are electrically connected with the conductive housing. Pins 5
and 6 are electrically unconnected. It is recommended that pins 5 and 6 be connected to Rx ground to reduce coupling of electrical
noise. Refer to Figure 1. The connections between pins 1 and 2 of the HFBR-5527 and pins 13 and 12 of the MC10H116 should be
adjacent and nearly the same length to maximize the common mode rejection of the MC10H116 to eliminate cross talk between the
transmitter and receiver.
10. If there is no input optical power to the receiver (no transmitted signal) electrical noise can result in false triggering of the receiver.
In typical applications, data encoding and error detection prevent random triggering from being interpreted as valid data.

receiver, the analog HFBR-5527
component must be connected to
a post amplifier and a comparator. This post amplifier plus
comparator function is commonly
known as a quantizer. The 0 V
common and +5 V power supply
connections for the HFBR-5527
and quantizer must be isolated
from the host system’s power and
ground planes by a low pass
filter. This recommended low pass
174
filter assures that the electrical
noise normally present in the
host system’s digital logic power
supply will not reduce the
sensitivity of fiber-optic receivers
implemented with the
HFBR-5527. The quantizer and
power supply filter circuits
recommended for use with the
HFBR-5527 are shown in
Figure 7 of HP Application
Note 1066. For optimum
performance, the HFBR-5527
should be used with the same
quantizer and power supply
filters recommended for use with
HP’s HFBR-15X7 and
HFBR-25X6 components. To
maximize immunity to electrical
noise, pins 3, 9, and 10 of the
HFBR-5527 should be connected
to filtered receiver common. For
best common mode noise
rejection, the connections
between pins 1 and 2 of the
HFBR-5527 and the quantizer’s
differential input should be of
equal length, and the components
in both traces should be placed to
achieve symmetry. The preceding
recommendations minimize the
cross talk between the fiber-optic
transmitter and receiver. These
recommendations also improve
the fiber-optic receiver’s
immunity to environmental noise
and the host system’s electrical
noise.
