Custom Coding Service: We offer free on-site EEPROM coding to match your exact switch requirements. Simply specify your switch brand and model in the order notes, or contact our engineers for special OEM requirements.

OPTONE Quality Control & Testing Assurance

To ensure zero-failure deployment in mission-critical enterprise networks and data centers, our manufacturing process undergoes multi-tier testing:

Laser & Chip Screening: Incoming laser diodes and ROSA/TOSA components undergo high-temperature aging and electrical parameter screening.

Optical Performance Test: Every module is tested for Optical Output Power, Extinction Ratio, Center Wavelength, and Eye Diagram mask margin using high-precision Agilent/Keysight testing equipment.

Switch Burn-In Test: Modules are placed in live switches to undergo prolonged traffic stress tests (24-48 hours continuous traffic forwarding) to eliminate infant mortality.

Traceability: Each module features a unique laser-etched serial number and barcode linked to its individual test report.
