TOT-300 Series single mode OTDR--High Dynamic Range

1310/1490/1550/1625nm; Up to 42/40dB High Dynamic Range

Product Description

OTDR, to test attenuation coefficient, loss of A and B points, splicing loss, fiber length,

distanceof A and B points, identify splicing points, fault points and direction of breaking points of optical fiber and cable. It shows curve of loss.Built-in VFL can test the fault direction of patch

cord. It has high capacity battery to last filed work.

TOT-300 Series OTDR developed for FTTx, which meet the needs on the wide range of measurement by FTTx,Metropolitan Area Network,Backbone Network and other optical networks.

Remarks: 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 180km/20480ns/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.
