This design allows the HFBRXX transmitters to be driven at a relatively low current level for a specified amount of coupled power into the fiber. Because transmitter forward currents are proportional to failure rates, a low current translates into excellent transmitter reliability.

To further improve reliability, Agilent has implemented a proprietary wafer screening technology that identifies dislocations which can lead to the formation of darkline defects the primary mechanism for transmitter light output failures.

When this is true, transmitter reliability will be substantially better. Reliability Prediction Model The reliability prediction model used to project failure rate and mean time to failure MTTF at various temperatures shown in the second table assumes an exponential cumulative failure function constant failure rate. The Arrhenius temperature derating equation is used.

Agilent Technologies assumes no failure mechanism change between stress and use conditions. A conservative activation energy of 0. Confidence intervals are based upon the chi-squared prediction method associated with exponential distributions. Failure Criteria Failure has occurred when the unit fails catastrophically, or when the light output power decreases 3 dB.

The point MTTF representing an estimate of the mean point MTTF is the total device hours divided by either the number of failures or unity if there are no failures. This confidence interval is based on the statistics of the distribution of failures. The assumed distribution of failures is exponential. This particular distribution is commonly used in describing failure rates prior to the onset of wear out. Failure Criteria Failure has occurred when the unit fails catastrophically.

One device failed to switch logic states. This particular distribution is commonly used in describing useful life failures.

Brush after solvent immersion. The Connector Side Load testing required that the housing be held so to prevent the leads from yielding. The load was applied through a SMA connectored fiber optic cable, perpendicular to the port.

The product family is designed to limit cable and ferrule damage due to cable loading. The support and active leads should yield before damage to the cable or connector occurs. The Port Strength test was designed to gauge the concerns with hand tightening the connector to the fiber optic port. The limit is set to a level beyond most reasonable hand fastening loading. Package tests are defined as stresses that indicate the environmental strength of the package.

Units tested indicate the total number of devices taken from the product family. While not all part numbers have been subjected to each stress, worst case products have been included.
