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.
