Optical Link Test OLT 880 Programming the Test Sequence with NT Control and the Optical Link Editor The Windows® application, NT Control, manages and controls the OLT boxes and the fiber optic adapters connected to the test system. In programming mode, the Optical Link Editor allows the simple editing of fiber optic connections. The measurement channels and limits of optical attenuation can be programmed individually for each fiber optic cable. In test mode, NT Control controls the automatic test of the fiber optics. On this occasion, the fiber optics are tested for observance of the programmed attenuation Automatic Testing of Fiber Optic Cables limits. The measurement method corresponds to the Fiber optic cables are being increasingly used in automobiles and in mechanical engineering. Plastic fiber optics (POF - Polymer Optical Fiber) are Visualization of the Test Results becoming predominant in these areas. The display of test results is clear and extensive. The During final test of cables and wire harnesses, the graphical fault display makes an important contribution testing of fiber optic cables is required in addition to to the fast location and systematic elimination of faults. electrical testing. The OLT 880 test box, in Report printing and label printing are also available. connection with adaptronic wiring test systems, allows the simultaneous testing of several fiber optic System Calibration cables in wire harnesses. NT Control supports suitable calibration procedures allowing the traceability of the calibration of the optical Multi-Channel Test Unit with High Precision channels. Not only the optical channels of the OLT box This multi-channel test unit has optical transmitters but also the fiber-optic patch cables to the adapters are (LEDs) and precise power-measurement units taken into account during calibration. integrated into one housing. 8 transmitting and The fiber-optic patch cables support homogeneous receiving channels are available. If more than 8 energy distribution into the light modules (EMD- channels are required, additional OLT boxes can be Equillibrium Mode Distribution) and offer high flexibility in the design of the fiber optic adapter. After changing Special characteristics of OLT 880 are the high fiber-optic adapters or service activities on the optical measurement precision and simultaneous high test test pins, the test system can simply and quickly be re-

Optical Link Test The connection of the fiber optic connectors is done via our well known AT4000 adaption system. This adaption system can be used for purely optical as well as for hybrid connectors (electrical and optical contacts). The electrical and optical test pins are spring-loaded and can be changed individually. The connection between the optical test pins and the OLT box is made with fiber-optic patch cables (POF). The attenuation of the individual fiber-optic patch cables is taken into account during system calibration. Technical features Optical interface Transmission channels...
