Main Features
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.
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.
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.
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
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.
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.
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.
