Jingyi Optoelectronics Custom Quartz Optical Fiber: Optical Transmission Solutions for Diverse Applications
The rapid expansion of three key domains—computing-power networks, industrial digitalization, and precision optical sensing—is imposing unprecedented, stringent performance requirements on optical transmission media. Within data centers, PB-scale data exchange demands higher bandwidth; in industrial environments with strong electromagnetic fields, signal transmission must achieve zero packet loss; and for precision spectroscopic analysis, ultra-low optical signal attenuation is essential. Conventional copper cables and standard plastic optical fibers are no longer capable of meeting these specialized application requirements. High-purity multimode quartz optical fiber—leveraging its unique performance advantages—is emerging as the preferred optical transmission solution across industries.
Jingyi Optoelectronics’ full-range customized multimode quartz optical fiber utilizes quartz raw material with 99.999% purity for its core. By precisely engineering the refractive index difference between the core and cladding layers, light signals entering at various incident angles undergo total internal reflection within the core—effectively creating dozens of parallel optical transmission pathways. This design fundamentally eliminates crosstalk among signals while ensuring stability over extended distances.
This fiber’s core advantages align precisely with today’s industry-specific requirements:
1. **Ultra-Broadband Compatibility**: It supports seamless transmission across the entire spectrum—from deep ultraviolet (DUV) to mid-infrared (MIR). Its single-fiber bandwidth exceeds that of traditional copper cable by over 1,200×, fully satisfying current data center interconnect requirements for 400G/800G speeds—and remains future-proof for upcoming 1.6T standards without requiring infrastructure rewiring.
2. **Exceptionally Low Transmission Loss**: Through a proprietary quartz purification process, Jingyi’s fiber achieves an attenuation as low as 0.28 dB/km in standard communication bands. Even over a 3-km transmission distance, optical signal attenuation remains under 20%, eliminating the need for costly repeater amplifiers and significantly reducing deployment costs.
3. **Robust, Universal EMI Immunity**: As an all-optical transmission medium, it is completely immune to high-voltage electric fields, electromagnetic radiation from industrial welding equipment, and lightning-induced interference. In complex electromagnetic environments—such as substations or underground mines—signal accuracy remains consistently above 99.999%.
4. **Highly Flexible Application Adaptability**: Fully customizable in core diameter and protection rating, the fiber is compatible with LC/FC connectors for telecommunications and SMA connectors for optical sensing applications. Whether deployed in server rooms, outdoor buried installations, or harsh industrial settings—characterized by high temperature and humidity—the solution can be flexibly tailored to meet specific environmental and operational needs.
Jingyi’s customized multimode quartz optical fiber has already achieved large-scale commercial adoption across multiple sectors:
- In **computing infrastructure**, several leading Chinese internet companies have adopted this fiber for top-of-rack (TOR) switch-to-server interconnects in newly built data centers. Compared with conventional copper cabling, overall deployment costs were reduced by 32%, and operations & maintenance efficiency improved by over 40%.
- In the **industrial internet** sector, automotive OEMs and lithium battery manufacturers deploy it for control-signal transmission in welding and coating workshops—effectively resolving prior production disruptions caused by electromagnetic interference, and increasing average equipment utilization (OEE) by 16%.
- In **precision sensing**, Jingyi’s multimode quartz fiber integrates seamlessly with its proprietary miniature spectrometers and calibration light sources to build end-to-end spectral measurement systems for food safety testing, water quality monitoring, and materials analysis. Due to its ultra-low optical loss, measurement accuracy improves by over 22% compared with systems using standard optical fibers.
- Beyond these areas, the fiber is also employed in medical laser delivery and fiber-optic biosensing for human physiological monitoring. Its excellent biocompatibility and stable transmission performance have earned recognition from multiple medical device manufacturers.
As optical technologies continue penetrating deeper into vertical industries, the application scope of multimode quartz optical fiber keeps expanding. Jingyi Optoelectronics is continuously advancing related manufacturing processes and has already launched specialized customized variants—including bend-insensitive multimode fiber and deep-ultraviolet low-loss multimode fiber. Going forward, the company will deliver increasingly targeted optical transmission solutions to accelerate digital and intelligent transformation across diverse industries.
