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. DITH is the maximum deviation
from the 25ºC value.
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.
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.
RIN12 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
