特点
VFI2小红光故障检查器是采用650nm的红色激光，从弯曲度过或被覆层断点或裸纤处射出，从而寻找故障位置。小红光也是OTDR的补充工具，它协助找到OTDR盲区故障点。它的另一些功能包括端到连续性检查，识别接头支架的连接头，熔接光纤时识别光纤等。

NOYES VFI2 visible red laser sources are designed to troubleshoot faults on fiber optic cables. Light generated by these units will escape from sharp bends and breaks in jacketed or bare fibers, as well as poorly mated connectors. They can quickly identify faults in fiber optic jumper cables, distribution frames, patch panels, and splice trays.
The VFI2 is an excellent complement to any OTDR because it can locate faults inside the OTDR’s dead-zone. Other applications include end-to-end continuity checks, identifying connectors in patch panels and fibers during splicing operations. The universal connector interface provides fast operation with many connector styles without changing an adapter.
Trace cables in crowded or un-documented setups. A VFI2 provides a quick means of finding the “other end” from amongst cluttered cables. Simply connect the VFI2 to one end and look for the visual red light transmitted out the opposite connector.
