AFCT-5745NPZ/ANPZ, AFCT-57J5ANPZ
& AFCT-5745UPZ/AUPZ
Family of Singlemode SFP Transceivers for Long Reach SONET OC-48
and SDH/STM-16 with Digital Diagnostic Monitoring (DMI) Interface
Reliability Data Sheet
Introduction
FIT Rate Summary
Avago Technologies Quality system includes an ongoing
Reliability Monitoring program to generate a database
from which this reliability datasheet is published.
FIT rate for AFCT-5745NPZ/ANPZ & AFCT-57J5ANPZ is calculated as 252.14; FIT rate for AFCT-5745UPZ/AUPZ is calculated as 252.14.
Description
The details of this calculation are included in this report.
The AFCT-5745xxxZ is high performance, effective modules for serial optical data communications applications
that range from 125 Mb/s to 2.7 Gb/s. They are designed
to provide SONET/SDH compliant links at 2488 Mb/s for
both short and intermediate reach links.
Conclusion
The transmitter section of the AFCT-5745NPZ/ANPZ & AFCT-57J5ANPZ incorporates a 1300 nm Distributed Feedback (DFB) laser. The transmitter in the AFCT-5745UPZ/
AUPZ uses a 1550 nm Distributed Feedback (DFB) Laser.
For each device the receiver section uses an Avalanche
Photodiode (APD). A positive-ECL logic interface simplifies interface to external circuitry.
Reliability Qualification
The optical transceivers and receivers have been qualified in accordance with the requirements of Telcordia
Document GR-468-CORE. Reliability predictions follow
the method of Telcordia-SR-332. Avago internal test specifications have also been applied. Testing was carried out
under the supervision of Avago Technologies Quality &
Reliability Department.
Stress Test Pass Criteria
Product failure has occurred when the unit fails to respond
properly to a functional test. The functional test condition
shall not exceed the absolute maximum or minimum data
sheet limits.
AFCT-5745NPZ/ANPZ & AFCT-57J5ANPZ and AFCT5745UPZ/AUPZ have completed and passed the reliability
qualification criteria defined by Avago Technologies’ Quality and Reliability requirements.
Random Failure Rate (FIT) Calculation
Failure in time rate, or FIT, is defined as the number of
failures per billion device hours. In the product useful life
region, the random failure rate is considered as a constant
failure rate. In this region MTTF, Mean Time to Failure, is
defined as MTTF = 1/FIT.
FIT Prediction Based on Telcordia SR-332 Parts Count
Procedure
The Telcordia parts count method assumes that the module failure rate is equal to the sum of the device component failure rates. Modifiers are included to take into consideration variations in module operation environments,
device quality requirements, temperature, and stress. The
tables that follow show the FIT for the components used
in the modules and the total FIT which have been calculated for an operating ambient temperature of 40°C.

FITs at other temperatures can be derived following the procedure of Telcordia-SR332, assuming activation energy, Ea,
of 0.35eV to determine the component temperature factor πT. The following table shows FITs at different temperatures
for the transmitter, receiver, and transceiver.

The limitations of FIT prediction based on the Parts Count method include the fact that the piece part failure rates are
mostly obtained from the Telcordia database, which may not be exhaustive for state-of-the-art piece parts, and that
the results are independent of true module environmental stress tests. Nevertheless, the information obtained from
the Parts Count method is a useful reference during design-in and evaluation. Whenever possible, Avago substitute’s
internal data for the FIT rates of individual components, and predictions will be updated as more current data becomes
available.
Accelerated Aging Tests
Product integrity is also verified by Accelerated Aging. Tables 3a and 3b summarize the High Temperature Operating Life
stress (HTOL) performed on the product. On-going reliability monitoring will continue to add to the total device hours
