DATA
SHEET
The HFD6180-420 uses a high-performance GaAs PIN photo-detector
packaged with a transimpedance amplifier designed to meet performance
requirements for 10Gbps data communication over multi-mode optical fiber at
850nm. Applications include Ethernet, Fiber Channel and ATM protocols. The
optical assembly is designed to interface either 50µm or 62.5µm multi-mode
fiber.
The HFD6180-421 is designed to be paired with Advanced Optical
Components HFE6x9x VCSEL 10Gbps TOSA products (see data sheets for
HFE6x9x products at www.finisar.com/aoc.php).

NOTICE: Stresses greater than those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation
of the device at these or any other conditions above those
indicated in the operations section for extended periods of
time may affect reliability.
NOTICE: The inherent design of this component causes it
to be sensitive to electrostatic discharge (ESD). To prevent
ESD-induced damage and/or degradation to equipment, take
normal ESD precautions when handling this product

NOTES
1. The data rate can be increased to 12.5Gbps, but the
sensitivity will be decreased by approximately 3dB.
2. PR is the average optical power at the fiber face.
3. PR OMA is the peak to peak optical power at the fiber face
(Optical Modulation Amplitude)
where ER is the extinction ratio (linear) of the optical
source.
4. Bandwidth and Low Frequency Cutoff are measured with
a small signal sinusoidal light source with –10dBm
average power
5. Sensitivity is measured with an optical source with an
extinction ratio of 3dB.
6. Stressed receiver sensitivity is measured with 3.5dB
vertical eye closure (intersymbol interference) and with
0.3UI of jitter added. The measurement technique is
defined in IEEE 802.3ae.
7. Rise/Fall times are corrected for optical source Rise/Fall
times. The corrected value is calculated as the square root
of the difference of the squares of the measured
differential detector output and the source.
8. Value shown is with external power supply filtering.
9. For best sensitivity, a limiting amplifier may be required
for operation.
10. The PD voltage must be connected to a positive 3.3V
power supply (nominal).

ADVANCED OPTICAL COMPONENTS
Finisar’s ADVANCED OPTICAL COMPONENTS division was
formed through strategic acquisition of key optical compon-
ent suppliers. The company has led the industry in high
volume Vertical Cavity Surface Emitting Laser (VCSEL) and
associated detector technology since 1996. VCSELs have
become the primary laser source for optical data communi-
cation, and are rapidly expanding into a wide variety of sensor
applications. VCSELs’ superior reliability, low drive current,
high coupled power, narrow and circularly symmetric beam
and versatile packaging options (including arrays) are enabling
solutions not possible with other optical technologies.
ADVANCED OPTICAL COMPONENTS is also a key supplier of
Fabrey-Perot (FP) and Distributed Feedback (DFB) Lasers, and
