A handheld fibre optic visual fault locator that helps pinpoint breaks, bends and connectivity faults for installers and maintenance teams. Confident fault finding keeps projects on schedule and reduces repeat visits. Is the OCEANCOMM Fiber Optic Tester the right tool for everyday field use?

⚡ At a Glance
  • Detection Capability: Detects continuity and locates fibre breaks, bends and OTDR blind zone errors
  • Best for: Field technicians and installers needing quick identification of physical fibre faults
  • Not ideal for: Users requiring full OTDR trace analysis and detailed loss measurements

Handheld visual fault locator for identifying breaks and bends with straightforward operation. Pen-type form suits quick checks during installation and maintenance.


Rapid fault location, with 30km visual range

Pen-type visual fault locator injects light into the fibre so discontinuities become visible along the cable, permitting checks over long runs specified in the product name. Optical continuity and localised faults are revealed without needing full OTDR traces.

Fast identification of visible breaks and bends across long cable runs, reducing time spent hunting faults on site. Portable operation speeds up routine testing and handover checks.

Connector flexibility, with 1.25mm universal detector plug

Detector plug accepts 1.25mm interfaces and is compatible with ST, SC, FC and LC connector types while accommodating both circular and square connector shapes. An FC male to LC female adapter is included for immediate use on common links.

Simplifies testing across mixed installations without searching for multiple converters. Ready-to-use compatibility reduces preparation time on multi-connector sites.

Find faults in hard-to-see areas, with OTDR blind zone detection

Visual fault location targets errors located in the OTDR blind zone, a region near connectors where OTDR traces can be ambiguous. Visual illumination of the fibre helps reveal faults that an OTDR may not resolve close to terminations.

Complimentary use with OTDR equipment improves confidence in diagnosing connector-side and near-end faults. Avoids repeated site attendance for problems that otherwise remain unclear.
