HFBR-5805/ 5805T/ 5805A/ 5805AT ATM
Transceivers for SONET OC-3/ SDH
STM-1 in Low Cost 1 x 9 Package Style
Data Sheet
Features
• Full compliance with ATM forum
UNI SONET OC-3 multimode fiber
physical layer specification
Description
Transmitter Sections
• Multisourced 1 x 9 package style
with choice of duplex SC or
duplex ST* receptacle
• Wave solder and aqueous wash
process compatibility
• Manufactured in an ISO 9002
certified facility
• Single +3.3 V or +5.0 V power
supply
The HFBR-5800 family of
transceivers from Agilent
provide the system designer
with products to implement a
range of solutions for
multimode fiber SONET OC-3
(SDH STM-1) physical layers
for ATM and other services.
The transmitter section of the
HFBR-5803 and HFBR-5805
series utilize 1300 nm InGaAsP
LEDs. These LEDs are
packaged in the optical
subassembly portion of the
transmitter section. They are
driven by a custom silicon IC
which converts differential
PECL logic signals, ECL
referenced (shifted) to a +3.3 V
or +5.0 V supply, into an
analog LED drive current.
The transceivers are all
supplied in the industry
standard 1 x 9 SIP package
style with either a duplex SC
or a duplex ST* connector
interface.
Applications
• Multimode fiber ATM backbone
links
• Multimode fiber ATM wiring
closet to desktop links
Receiver Sections
ATM 2 km Backbone Links
The receiver section of the
HFBR-5803 and HFBR-5805
series utilize InGaAs PIN
photodiodes coupled to a
custom silicon transimpedance
preamplifier IC. These are
packaged in the optical
subassembly portion of the
receiver.

Package
The outer housing including
the duplex SC connector or
the duplex ST ports is molded
of filled nonconductive plastic
to provide mechanical strength
and electrical isolation. The
solder posts of the Agilent
design are isolated from the
circuit design of the
The transceiver is attached to
a printed circuit board with
the nine signal pins and the
two solder posts which exit
the bottom of the housing. The
two solder posts provide the
primary mechanical strength to
withstand the loads imposed
on the transceiver by mating
with duplex or simplex SC or
ST connectored fiber cables.
The overall package concept
for the Agilent transceivers
consists of three basic
elements; the two optical
subassemblies, an electrical
subassembly and the housing

square-wave) input signal, the average
optical power is measured. The data “1”
peak power is then calculated by adding
3 dB to the measured average optical
power. The data “0” output optical power is
found by measuring the optical power when
the transmitter is driven by a logic “0” input.
The extinction ratio is the ratio of the optical
power at the “0” level compared to the
optical power at the “1” level expressed as
a percentage or in decibels.

3. The power supply current needed to operate
the transmitter is provided to differential
ECL circuitry. This circuitry maintains a
nearly constant current flow from the power
supply. Constant current operation helps to
prevent unwanted electrical noise from
being generated and conducted or emitted
to neighboring circuitry.
• Receiver data window time-width is
1.23 ns or greater for the clock recovery
circuit to operate in. The actual test data
window time-width is set to simulate the
effect of worst case optical input jitter
based on the transmitter jitter values
from the specification tables. The test
window time-width is HFBR-5805 3.32 ns.
10. The transmitter will provide this low level of
Output Optical Power when driven by a logic
“0” input. This can be useful in link
troubleshooting.
11. The relationship between Full Width Half
Maximum and RMS values for Spectral
Width is derived from the assumption of a
Gaussian shaped spectrum which results in
a 2.35 X RMS = FWHM relationship.

The optical rise and fall times are measured
from 10% to 90% when the transmitter is
driven by a 25 MBd (12.5 MHz square-wave)
input signal. The ANSI T1E1.2 committee
has designated the possibility of defining an
eye pattern mask for the transmitter optical
output as an item for further study. Agilent
will incorporate this requirement into the
specifications for these products if it is
defined. The HFBR-5805 products typically
comply with the template requirements of
CCITT (now ITU-T) G.957 Section 3.2.5,
Figure 2 for the STM-1 rate, excluding the
optical receiver filter normally associated
with single mode fiber measurements which
is the likely source for the ANSI T1E1.2
committee to follow in this matter.
5. The power dissipation value is the power
dissipated in the receiver itself. Power
dissipation is calculated as the sum of the
products of supply voltage and currents,
minus the sum of the products of the output
voltages and currents.
15. All conditions of Note 14 apply except that
the measurement is made at the center of
the symbol with no window time-width.

with the following conditions:

from low to high levels of input optical
power.
• The Beginning of Life (BOL) to the End of
Life (EOL) optical power degradation is
typically 1.5 dB per the industry
convention for long wavelength LEDs.
The actual degradation observed in
Agilent’s 1300 nm LED products is
< 1 dB, as specified in this data sheet.

the requirements for the trade-offs between

IEC 9314-3 : 1990 and ANSI X3.166 - 1990)
