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.
ΔI
TH
is the maximum deviation from the 25ºC value.
3. Slope efficiency is defined as
ΔP
O
/ΔI
F
at a total power output of 0.47mW. Slope efficiency is intentionally lowered to the value
shown by attenuation.

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.
RIN
12
is measured using the OMA technique with 12dB return.
Total capacitance is measured with the VCSEL forward biased using a Network analyzer at 1GHz.
Encircled flux is measured per TIA-455-203.
To prevent VCSEL damage, short the VCSEL anode and cathode during BVR testing of the photodiode.
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 I
PD
needs to be measured for a
fiber coupled power of -3, -3.3, and -4 dBm, respectively. The BOL tracking profile then includes the recorded I
PD
values at -3 dBm
for -5C, -3.3 dBm for 25C, and -4 dBm at 85C. This programming can be derived from room temperature measurements;
measurement over temperature can be used for increased accuracy. A typical BOL OMA for this setup would be 380 uW.
