At YFY, quality is not the final step—it is engineered from the beginning. Every passive optical network component must survive heat, vibration, bending cycles, UV exposure, and long-term signal transmission without degradation. To guarantee this level of performance, we build reliability through controlled processes, certified systems, and verifiable test data—not assumptions or visual inspection.
How does YFY assure telecom productʼs quality?
RoHs & REACH: Environmental & Material Qualification
At YFY, quality is not just a requirement—it is the foundation of everything we do. Every fiber optic and passive telecom product must be engineered for field reliability, long-term performance and precision signal integrity.
Our quality commitment is inseparable from environmental responsibility. All materials & production comply with RoHS & REACH, verified through supplier audits, documentation trails and continuous regulatory monitoring.
ISO 9001 / ISO 14001 Certified Quality Factories
YFY operates under a documented quality management framework where every process — from molding to final shipment — is traceable, standardized and continuously improved.
IQC – Incoming Quality Control as first denfenser
Incoming material inspection is the foundation of our quality assurance structure. We utilize a data-driven, system-based approach instead of simple visual checks:
Clear inspection standards
Standardized criteria for all raw materials.
AQL-based sampling
Fully recorded in MES for traceability.
Non-conforming material quarantine
Rapid supplier feedback mechanism.
Supplier performance tracking
Based on long-term statistical data.
This ensures stable sourcing and prevents defects from entering production.
IPQC – In-Process Quality Control with Real-Time Response
Our real-time production controls guarantee process stability and consistency:
Critical Control Points (CCP)
Established across key manufacturing stages.
Standardized work instructions
Detailed SOPs for every operation.
Real-time MES data logging
Complete traceability for every unit.
Immediate deviation handling
Root-cause analysis and correction.
Regular data reviews
Continuous process optimization.
Stability is preserved through data, not intuition.
Functional and Performance Testing
All final performance verification is conducted under standardized processes aligned with internationally recognized testing principles. To ensure long-term reliability of optical cabinets, closures, fiber connectivity products, and passive components, we reference applicable global standards, including:
Mechanical & Environmental Reliability
IEC61300 / ITU-T L.13 / GR771-CORE / IEC62262 / ASTM G155 / GR1221 CORE
Environmental Durability
IEC61300 / IEC 60529 / IEC 68-2
Optical Performance
GR-1209-CORE / IEC 61300
Carrier-Grade Requirements
Telcordia requirements (GR-series) when required
Only products fully meeting all testing benchmarks are released for shipment.
Final QC & Shipment Authorization
Before shipment, products undergo a secondary verification stage including optical reconfirmation, housing integrity review, torque accuracy inspection and packaging drop-simulation. Only zero-defect units reach the customer — no exceptions.
