In today’s era of high-speed data communication, the OMC Cable MPO Fiber Optic Patch Cord stands out for its high-density connectivity and ultra-low insertion loss. With the growing demand for faster and more reliable data transmission in 5G, cloud computing, and large-scale data centers, insertion loss has become a critical performance indicator.
For OMC Cable, achieving low insertion loss is not just a product specification—it’s the result of precise engineering, advanced manufacturing, and strict quality control. So, what exactly ensures the exceptional performance of the OMC Cable MPO Cord? Let’s explore the key factors behind it.
Precision Design for Accurate Signal Alignment
The foundation of low insertion loss lies in the accuracy of structural design. OMC Cable places great emphasis on optical alignment and connector geometry optimization during product development:
- End-face Geometry Precision: Each fiber end-face is polished to a microscopic level, with strict control of flatness, curvature radius, and fiber height difference. This ensures perfect fiber contact and minimizes air gaps that cause signal attenuation.
- Consistent Fiber Array Alignment: In 12, 24, or even 48-core MPO connectors, every fiber is precisely positioned within the alignment guide holes. This micron-level accuracy guarantees that optical axes are perfectly aligned, resulting in minimal transmission loss.
- Low-Reflection APC Structure: OMC adopts the APC (Angled Physical Contact)design with an 8° angled polish to effectively reduce back reflection and enhance the overall signal-to-noise ratio (SNR) of the transmission system.
Through such meticulous design, the OMC Cable MPO Cord ensures stable, low-loss connections even in high-density network environments.

Advanced Manufacturing Processes for Minimal Loss
OMC Cable integrates industry-leading fiber polishing and automated assembly technologies to achieve consistently low insertion loss across all MPO cords.
- High-Precision Polishing Technology
OMC uses imported fiber polishing equipment to achieve nano-level surface smoothness.The PC (Physical Contact) polish ensures standard-grade performance, while the APC polish provides superior reflection control, bringing average insertion loss down to as low as 20dB.
- Automated Alignment and Assembly
By adopting computer-vision-based alignment systems, OMC ensures each fiber core is positioned precisely during assembly. This automation not only eliminates human error but also ensures consistent quality across large production batches.
- Cleanroom Production and End-Face Inspection
All MPO cords are manufactured in ISO Class 1000 cleanrooms. Each connector end-face is inspected under high magnification to guarantee a dust-free, scratch-free, and defect-free finish.
This meticulous production control ensures that OMC MPO cords maintain ultra-low insertion loss and long-term performance reliability.
Premium Materials for Superior Stability
Material quality is one of the key factors affecting insertion loss and long-term performance. OMC Cable carefully selects world-class materials for every component:
- Optical Fiber Core
OMC sources high-grade low-attenuation fibers from global brands such as Corningand YOFC, ensuring high bandwidth, low dispersion, and stable signal transmission even over long distances.
- Outer Sheath and Buffer Material
The MPO cord jacket is made of LSZH (Low Smoke Zero Halogen)material, offering exceptional flexibility, flame resistance, and environmental safety, ideal for modern data centers.
- High-Precision Ferrules and Alignment Pins
Ceramic ferrules and stainless-steel guide pins maintain long-term stability and precise fiber alignment, preventing micro-misalignments that could otherwise increase insertion loss.
These premium materials ensure durability, stability, and consistent optical performance under varying environmental conditions.
Rigorous Testing to Guarantee Consistent Quality
At OMC Cable, every MPO cord undergoes comprehensive testing before shipment to ensure the lowest possible insertion loss and optimal performance.
- 3D Interferometer Testing
Used to analyze the connector end-face geometry, including radius, fiber height, and apex offset, to confirm compliance with industry standards.
- Insertion Loss & Return Loss Measurement
Each MPO cord is tested using professional IL/RL measurement equipment to ensure Insertion Loss ≤ 0.35dBand Return Loss ≥ 60dB.
- Environmental and Mechanical Reliability Tests
All products undergo temperature cycling, humidity, tensile, and bending tests to ensure long-term reliability in diverse environments.
OMC products fully comply with IEC 61754-7 and TIA-604-5 (FOCIS 5) international standards, and each cord comes with a detailed IL/RL test report for traceable quality assurance.
Conclusion
The low insertion loss of the OMC Cable MPO Cord is not a coincidence—it’s the result of precision engineering, advanced polishing technology, premium materials, and rigorous quality testing. For high-performance data centers, cloud infrastructures, and 5G optical networks, OMC provides fiber connectivity solutions that deliver high speed, reliability, and long-term stability.
