DATA
SHEET
The HFE6192-x61 uses a high-performance Vertical Cavity Surface Emitting
Laser (VCSEL) designed to meet performance requirements for 10Gbps data
communication over multimode optical fiber. Applications include Ethernet,
Fibre Channel and ATM protocols. The optical assembly is designed to inter-
face either 50µm or 62.5µm multimode fiber and ensure launch conditioning
requirements compatibility with enhanced bandwidth fiber as specified by
TIA 455-203.
The HFE6192-x61 incorporates a power monitoring photodiode that can be
used for temperature compensation, average power control, and for
compliance with Class 1 eye safety limits.

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. PO_PCT is defined as the ratio of the coupled power into
a 50/125 micron fiber to the total power output from the
optical front end as measured on a large area detector.
2. Operation outside of the specified range may result in the
threshold current exceeding the maximums defined in
the electro-optical characteristics table. ∆ITH is the
maximum deviation from the 25ºC value.
3. Slope efficiency is defined as ∆PO/∆IFat a total power
output of 0.6mW. Slope efficiency is intentionally lowered
to the value shown by attenuation.
4. Rise and fall times are sensitive to drive electronics. Rise
and fall times are measured 20%-80% using a 1GHz
square wave AC coupled to the VCSEL using a bias-T.
The DC current is adjusted to achieve a minimum
OMA of -4dBm. Corrections are made for finite
detector bandwidth.
5. RIN12 is measured using the OMA technique with
12dB return.
6. Total capacitance is measured with the VCSEL forward
biased using a Network analyzer at 1GHz.
7. Encircled flux is measured per TIA-455-203.
8. To prevent VCSEL damage, short the VCSEL anode and
cathode during BVR testing of the photodiode.

TYPICAL PERFORMANCE CURVES
RMS Spectral Width is defined and measured using
TIA-455-127
Threshold Current vs. Temperature: Threshold current
varies parabolically with temperature; thus it can be nearly
constant for a limited temperature range.

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.
