Return loss measures how much optical power is reflected back toward the transmitter due to imperfections at connectors, splices, or interfaces. In modern networks running at 10G, 100G, or even 800G s...

When an optical signal pulse hits an angled (APC) endface, the signal is reflected into the cladding of the fiber rather than back down the fiber core. This allows APC connectors to have low reflectance,
