OTDRs

Optical Time Domain Reflectometers (OTDRs) are critical test instruments utilized by associations to confirm the execution of new fiber optics interfaces and distinguish issues with existing fiber links. The resolute quality and nature of OTDRs depend on their exactness, estimation range, capacity to measure firmly spaced events, estimation velocity, and capacity to perform under different environmental extremes and after different sorts of physical misuses. The instruments are additionally judged on the premise of their cost, size, weight and convenience.

Functions of OTDR Test Equipment

OTDR test equipment is mainly used for testing long links. The information that the OTDRs produce is normally used to make a picture called a "trace" or "signature" that has significant data for the prepared client and can be stored for later reference or check against a blueprint when system inconvenience emerges. OTDR testers should not be utilized for measuring insertion loss for fiber optic cables. The tasks are better left to fiber optic test sources and power meters. OTDRs essentially demonstrate where the cables are ended and confirm the quality of them. OTDRs traces are utilized for troubleshooting since they can indicate where breaks are in fibers. The OTDRs comprise of a powerful laser transmitter that sends a pulse of light down the fiber. Back-scattered light and reflected light come back to the OTDRs through the fiber and are coordinated through a coupler in the OTDR tester’s front end. For every estimation, the OTDRs convey a powerful pulse and measure the light returning. Anytime, the light that the OTDRs see is the light scattered from the pulse going through an area of the fiber. The OTDR test equipment can correlate what they see in backscattered light with an actual location in the fiber. Thus, they can create a display of the amount of backscattered light at any point in the fiber along its length.

Features

The handheld OTDRs offered by GAO Tek are concise, compact, light in weight and portable. They have a touchscreen with multiple touch gestures feature. The results can be immediately uploaded to PC via different channels. The upgradable feature will keep them aligned with all the new generation features as well.
