Key product highlights:

Wide compatibility: Compatible with 10G/25G/100G/400G LC interface Optical Transceivers, single-core optical components, etc., covering all scenarios such as R&D testing, mass production verification, and on-site debugging.
Strong protection performance: Continues the patented design of the OES, transferring the LC port insertion loss to replaceable protective components, increasing the port insertion and removal lifespan by more than 4 times, effectively blocking dust and oil contamination from invading, and protecting the precise end face.
Compact and easy to integrate: Compact design suitable for high-density testing stations, not affecting the layout of existing testing equipment, plug-and-play, quick replacement, significantly improving testing efficiency.
Excellent performance indicators: Low insertion loss, high return loss, does not affect the transmission accuracy of the optical signal, ensuring accurate and reliable test results.

New Release of Multi-core Fiber Components: Unlocking New Solutions for High-Density Optical Interconnection

In line with the penetration trend of multi-core fiber (MCF) technology in the field of high-speed interconnection, QSTAR-LINK has simultaneously launched a series of new multi-core fiber component products, providing high-density, high-capacity, low-loss optical interconnection solutions for data centers, AI clusters, and high-speed optical modules.

Product Core Value:

High-density Transmission: Based on the multi-core fiber space multiplexing technology, a single fiber integrates multiple independent fiber cores, increasing the transmission capacity by 3-4 times, significantly saving wiring space, and adapting to 800G/1.6T and future higher-speed transmission requirements.
Full Series Coverage: Launching multi-core fiber fan-in/fan-out components, multi-core MPO connector components, and multi-core LC jumper components, achieving full coverage within and outside the module, seamlessly connecting with traditional single-mode fiber systems.
Low Loss and High Reliability: Utilizing precise coupling technology, with low insertion loss and strong stability, it has excellent bending resistance and vibration resistance performance, suitable for the strict operating environment of data centers.
Significant Cost Reduction and Efficiency Enhancement: Reducing fiber usage and wiring construction costs, shortening deployment cycles, and helping customers quickly build high-density, low-cost optical interconnection networks.

MPO Optical Extension Shield: Widely recognized in the market, leading in production scale

As the core product of QSTAR-LINK's OES series, the MPO OES has applied for Chinese and US patents. The product adopts an innovative port extension design, physically isolating the precise testing ports of the optical module from the testing equipment. It transfers the wear and tear caused by plugging and unplugging, as well as dust pollution, to low-cost and easily replaceable protective components, achieving long-term protection of the core end face of the optical module from a structural perspective. This product has become the benchmark for MPO interface testing protection of high-speed Optical Transceivers, and has achieved large-scale commercialization and leading production capacity.

Core solutions addressed:

Industry pain points	Optical Extension Shield (OES) solution
End face wears out quickly and has a short lifespan	A single OES can increase the port insertion and removal lifespan of the optical module by 3-5 times, significantly reducing the failure rate of ports due to frequent insertion and removal
End face is prone to scratches/pollution	Through internal isolation and intermittent protection, it effectively blocks dust and oil, reducing the proportion of end face damage during testing to below 0.5%
High cost	The Extender Shield is a replaceable device, with a cost much lower than replacing the optical module port, significantly reducing testing and maintenance costs
Poor environmental adaptability	Reduce reliance on a clean environment and minimize test yield fluctuations caused by environmental issues

Market application situation:

Deep coverage of 400G/800G/1.6T high-speed Optical Transceivers mass production testing, adapted to the batch testing requirements of data centers and AI computing clusters. It has been verified by many leading industry customers and achieved stable mass procurement.

It is widely used in the entire process of R&D reliability testing, customer on-site acceptance, and return-to-factory re-inspection, effectively solving the problem of end-face damage caused by high-frequency plugging and unplugging.

For scenarios with high requirements for polarization state stability such as coherent optical modules, fiber sensing, and quantum communication, the PM-OES model is provided to ensure test accuracy.

Production scale and delivery capability:

A mass production line has been established. The current monthly production capacity is stable at 30,000 units. It is planned to expand to 100,000 units in August this year, which can meet the large-scale and rapid delivery needs of global customers.

Self-built coating production capacity has been achieved, enabling full-process self-control, laying the foundation for quality control and continuous product optimization.

The production capacity has the ability to expand rapidly and can match the explosive demand for 1.6T and higher-speed optical modules in the future.
