Testing parallel optics demands a loopback that behaves like a real link. These MTP modules use authentic connectors and verified fiber paths so measured results reflect true channel performance.
Each loopback uses controlled fiber lengths and interferometry-verified end faces, so the loop adds a known, repeatable loss. That makes the modules suitable both for quick go/no-go checks and for precise sensitivity measurements.
