Optical correlation-domain reflectometry (OCDR) provides distributed reflectivity measurements with moderate range, high spatial resolution, and real-time capability. Conventional systems, however, rely on bulky instruments that hinder field use. We propose and experimentally demonstrate a remote-head OCDR, where only the fiber under test (FUT) and circulator are placed on-site, connected to the main system via kilometer-scale fibers. The reflectivity distribution of the FUT was clearly measured, with multiple reflection points detected and ~15 cm spatial resolution maintained. These results confirm the feasibility of remote-head OCDR and its potential for practical infrastructure monitoring.
