Mini Reflective Circulator Empowers AI Data-Center Optical Modules

As AI data centers and intelligent-computing clusters grow, data centers evolve toward 800G/1.6T high-speed optical interconnects, and Industry 4.0 drives the wide adoption of fiber sensing — optical modules, as core transmission units, face the dual challenges of space compression, signal integrity assurance and cost optimization. What is urgently needed are innovative optical component solutions combining low loss, high isolation and miniaturization.

Triple-Stone's Mini Reflective Circulator can be used in single-fiber bidirectional (BiDi) high-speed optical modules, allowing transmit and receive at the same wavelength and doubling the capacity of a single line — effectively reducing the cost of high-bandwidth data-center transmission networks.

Through innovative design and outstanding performance, the Mini Reflective Circulator has become a key component of optical network upgrades, helping customers build efficient, stable and intelligent all-optical connectivity.

Optimized Power, Higher Performance, Differentiated Value

1. Miniaturized Package

The Mini Reflective Circulator features a compact Φ2.4×15 mm package specially designed for space-limited modules. Its single-side fiber output effectively reduces internal fiber-coiling space, enabling further module miniaturization and multi-function integration.

2. Low Insertion Loss

Typical loss stays within 1.0dB with PDL below 0.2dB. The low insertion loss retains sufficient link-budget margin for single-fiber bidirectional transmission, ensuring data accuracy while helping reduce module power consumption.

3. High Isolation

High isolation (≥35dB) protects the signal source from reverse optical power interference while allowing return signals to exit through another port to the receiver.

4. High Directivity

Typical directivity ≥40dB effectively avoids crosstalk between the transmit end and the receive end.

5. High Reliability

Stable operation from −40°C to +85°C, meeting Telcordia GR-1221-CORE and passing 2,000-hour high-temperature, high-humidity testing.

Outstanding Performance, More Applications

The Mini Reflective Circulator supports multi-band customization across O/C/L bands, suiting AI data centers and intelligent-computing clusters, data-center optical interconnects, fiber sensing and monitoring, and quantum communication.

As communication technology advances, component performance requirements keep rising. The Mini Reflective Circulator delivers precise, efficient signal management, helping customers tackle complex technical challenges and meet the market demand for faster, more stable and more compact communication products.

Over the past two decades, Triple-Stone has focused on developing highly integrated, high-performance, reliable fiber-optic passive components. Beyond reflective circulators, our circulator series also includes standard circulators, free-space circulators, dual-path circulators, adapter-type circulators and circulator racks (for OCS).
