The FR-110 and FR-120 are compact, cost-effective portable single mode fiber fault-event data loggers. They are light, easy to use, and hence ideal for fiber cable troubleshooting, repairing, and restoration.
Just like an OTDR, the fiber ranger injects the laser pulse into the fiber under test and picks up scattered and reflected optical signals. However, the structure of fiber ranger is highly simplified to make it a low cost, high performance fiber optical test instrument. Although the fiber ranger does not either display the trace of the fiber or give any information about the fiber and event losses, it can identify types and locations of both bases on a set of pre-determined threshold values and goes throughout the entire length of the fiber under test. |
