The TREND Networks VFF5 projects a highly visible laser light source into fibre optic cabling. This is used to check continuity and locate breaks, poor mechanical splices, and damaged connectors. Used to test and find breaks in fibre links, locate pinched fibre strands in termination cabinets, or anywhere fibre optic cables are terminated and subject to mechanical damage.
The VFF5 is also an excellent aide to technicians terminating mechanical splices or pre-polished connectors where leaking light is an indicator of a poor fibre cleave or other misalignments.
