10G SFP+

Before shipment, transmit/receive function, EEPROM, DDM/DOM and burn-in are checked 100% unit by unit. Every module must be confirmed for normal optical output, normal receive function, correct internal data and monitoring readings within a reasonable range.

Based on the reliability model, the estimated wear-out failure rate under 40°C and 10-year use conditions is 205 FIT, corresponding to an equivalent MTBF level of about 4.8 million hours. Together with 100% burn-in and full outgoing inspection, this is the engineering basis for the 3-year warranty.

Depending on the product specification, we verify the relevant IEEE, SFF and MSA requirements, including the optical/electrical interface, form factor, pin definition and EEPROM/DDM data format. Standards compliance does not mean a module will be fully compatible with every brand of host equipment, because firmware, identification codes, alarm thresholds and compatibility policies can differ by platform. Standards guarantee basic specification and interface consistency; they do not replace real platform validation or directly represent product reliability or service life. We therefore treat standards compliance as the baseline, then confirm usability with actual testing and the customer's application conditions.

The most common misunderstanding is that if a module lights up and links, its quality is fine. In reality, differences in optical modules often appear only during long operation, temperature changes, limited optical power margin or platform-specific compatibility conditions. We therefore check not only whether the link comes up, but also transmit/receive function, DDM/DOM readings, burn-in results and required reliability validation. For optical modules, lighting up is only the baseline; stable operation is the real quality target.
