Mini OTDR specification

Mini OTDR Description :

JFOTDR-02 is a high performance mini-OTDR, small, lightweight and rugged. The most distinct feature of JFOTDR-02 is that it can measure both single mode fiber and multimode fiber. It also features the large color LCD, USB interface and long battery operation life. With this OTDR, you can measure unit /connection/transmission loss and locate faults  or  breaks  on  optical  fibers.  It  is  widely  applied  in  the manufacture, construction and maintenance of optical fibers

1. The technical specification describes the ensured performance of the instrument when  using typical
PC model connector to measure. Without considering the uncertainty caused by optical fiber refractivity.
2. Dynamic range is the data measured under the condition of the maximum  pulse width  and 3 minutes
of average time. Dynamic  range is the data measured under the condition of 100km/10240ns/3min.
3. Measuring conditions of blind zone: reflection event is within  4Km, reflection strength <  -35dB.
Measured by the minimum  pulse width.
4. Dynamic range measured when there is filter.
5. Dynamic range measured when there is no filter.
