Quality Management

Overview of Our Process

Quality Objectives

All of Yingda’s products of fiber connectivity and fiber cable termination boxes are manufactured in accordance with international standards of IEC, TIA, IEEE, Telcordia and strictly follow the quality inspection process to ensure reliable product quality and stable performance. They can only be shipped based on 100% qualified, and unqualified products are prevented from entering the market or customers. At the same time, all goods are recorded and traceability.

HOW TO DO

Strict Process Control

In order to achieve the above goals, Yingda adopt strict process controls as below: 

Material Inspection

All raw materials and parts are inspected and counted in real time, and then put into storage after evaluation, so that all materials are controllable, traceable and stable.

The company implements the 5S standardized process in production. Each workstation clearly annotates and explains the qualified requirements and unqualified handling methods in the form of documents and labels to prevent defects and unqualified products from flowing into the next link.

All finished products must be fully inspected to ensure that they meet the industry and order standards before they can be put into storage and shipped.

The company monitors the production status of each order in real time, corrects deviations in a timely manner, and statistically analyzes the reasons and promptly puts forward improvement suggestions to provide reference for subsequent order processing.

All test and production equipment are regularly maintained to ensure normal operation of the equipment; measuring equipment is regularly calibrated to ensure its accuracy and good condition.

Safety production management personnel will check all spaces such as the company’s internal, production lines, warehouses and material reserves from time to time to prevent accidents, reduce or eliminate risks, and ensure that the production environment meets the requirements, prevent accidents from affecting production, and ensure the safety of employees’ lives and property.

WHAT WE DO

Internal Quality Control

All Yingda’s fiber connectivity and fiber cable termination boxes are manufactured in accordance with international standards of IEC, TIA, IEEE, Telcordia and strictly follow the quality inspection process to ensure reliable product quality and stable performance. They can only be shipped based on 100% qualified, and unqualified products are prevented from entering the market or customers. At the same time, all goods are recorded and traceability.

1

internal quality control fiber array
Fiber Array Checking

All coming materials will be checked by standard process to ensure the quality, and avoid problems from the beginning.

2

internal quality control endface check
Endface Checking

All pre-terminated fiber optic cable will be polished and grinding in factory firstly, so end face microscope checking is a must to endure top quality.

3

internal quality control polarity check
Polarity & Sequence Test

For multi fiber connectors like MPO/MTP, will check the polarity or fiber sequence to ensure perfect docking with optical terminal equipment.

4

internal quality control polarity check
IL & RL Test

All pre terminated products such as fiber optic patch cords, fiber optic pigtails, MPO patch cord must be tested for insertion loss and return loss to ensure the lowest fiber access at ONU ONT side.

5

internal quality control 3 dimension test
3 Dimension Interferior

According to the IEC standard, three technical parameters are generally specified for PC-type connectors: radius of curvature, vertex offset and fiber height.

6

internal quality control tension strength
Tension Strength

Many FTTH drop cable are installed overhead or in pipes. At this time, the tension value of the optical fiber cable directly affects the quality and loss of terminal distribution wiring.

LAB SUPPORT

Third Party Certificates

In order to meet the project requirements or special needs of customers, in addition to internal testing, Yingda can cooperate with customers to do third-party testing and certification. Please inform the specific product parameter requirements in advance. After evaluation, our company will provide samples to the testing agency, and then the testing agency will issue a test report to the customer.
