High performance VCSEL
Low electrical parasitic TO package
with flexible interface
Data rates from DC to 12.5Gbps
Complete isolation between the
VCSEL, Monitor Photodiode and Case
Mechanically compatible with all
10Gbps MSAs
The HFE6x92-761 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 50 m or 62.5 m
multimode fiber and ensure launch conditioning requirements compatibility with
enhanced bandwidth fiber as specified by TIA 455-203.
The HFE6x92-761 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. DITH is the maximum deviation
from the 25ºC value.
3. Slope efficiency is defined as
∆PO/∆IF
at 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
