NOTES
5.
RIN12 is measured using the OMA technique with 12dB
return.
1.
6.
Encircled flux is measured per TIA-455-203.
7.
To prevent VCSEL damage, short the VCSEL anode and
cathode during BVR testing of the photodiode.
8.
Operation of the HFE7192-xxx is critically dependent
upon the quality of the electrical interface between the
TO can and the customer PCB. All specifications are tested
with the optional flex interface circuit. Modulation
performance without the flex circuit will be impaired
9.
Using recommended bias profile shown below. OMA level
is for beginning of life and accounts for aging.
2.
3.
4.
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.
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.
Slope efficiency is defined as ∆PO/∆IF at a total power
output of 0.47mW. Slope efficiency is intentionally
lowered to the value shown by attenuation. See
recommended Bias Profile below for POC setup details.
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.
RECOMMENDED BIAS PROFILE
In order to maintain maximum output quality while
maintaining an ample high temperature margin for reliability
and rollover, a temperature dependent bias profile is
recommended. To define this profile, the back monitor current
IPD needs to be measured for a fiber coupled power of -3, -3.3,
and -3.5 dBm, respectively. The BOL tracking profile then
includes the recorded IPD values at -3 dBm for -5C, -3.3 dBm
for 25C, and -3.5 dBm at 85C. This programming can be
derived from room temperature measurements; measurement
over temperature can be used for increased accuracy.
