Main Features

01 Ultra-Low Inter-Core Crosstalk

Uncompromised Signal Integrity

In Space Division Multiplexing, channel isolation is critical. Our precision-engineered MCF-FIFO devices guarantee inter-core crosstalk of ≤-45dB, ensuring that high-density data streams remain distinct and interference-free across all cores.

02 Versatile Coupling Architecture

Adaptable to Any Network

Whether you are splicing directly to backbone cables or patching into existing racks, the MCF-FIFO supports both bare fiber fusion splicing and direct pluggable coupling utilizing standard LC, SC, or FC connector interfaces.

03 Rugged, High-Reliability Packaging

Environmentally Hardened

Housed in a robust 55×7.3×4mm enclosure, the delicate multicore-to-single-mode transition is fully protected. Engineered for extreme environments, it delivers stable, dependable optical performance from -40°C to +85°C.

04 SDM System Enabler

Ready for Next-Gen Bandwidth

Break through the single-mode capacity crunch. The MCF-FIFO is the core component that makes high-density multicore fiber deployments practical, transitioning 4 or 7 discrete channels into a single physical spatial footprint.

Deployment Scenarios

01 High-Density Data Centers

Maximize Interconnect Density

As hyperscale data centers exhaust their existing duct space, multicore fibers offer a path to multiply capacity without laying new cables. The MCF-FIFO seamlessly breaks out these massive data pipes into standard single-mode patch panels for routing to individual transceivers.

02 Long-Haul Backbone Transmission

Extend the SDM Backbone

Space Division Multiplexing is revolutionizing long-haul optical networks by combating nonlinear optical limits. Deploy MCF-FIFO modules at amplifier sites and terminal nodes to efficiently inject and extract discrete channels from long-haul multicore cables.

03 Fiber Optic Sensing

Multi-Parameter Precision

In advanced distributed optical fiber sensing applications, multiple cores can measure different physical parameters (like temperature, strain, and vibration) simultaneously. The MCF-FIFO cleanly routes each sensing core to its dedicated interrogator channel.
