Why This Architecture Matters

All-fiber Construction

No free space, improves reliability, high tolerance to shock/vibration, less susceptible to contamination.

Scalable

Rack systems can be built to incorporate as many modules as needed to achieve power target.

Wide Input Voltage Range

Designed to be powered directly from battery, 250-400 VDC, no additional electronics needed.

Customizable Output Fiber Delivery

Small form factor endcap terminations to enable small-pitch combiner arrays.
