This hands-on Tips for Techs video takes you inside the Black Box Training Center to show you how to terminate and test cabling for a copper installation. The video begins... more/see it nowwith a step-by-step demonstration of terminating a patch cable up to the CAT6 specification, with special focus on how to cut and strip the cabling in a way that ensures good signaling integrity. Next, it covers how to validate and verify a backbone link between a patch panel and workstation. The video tutorial then demonstrates what kind of tester you’ll need if you must certify and document a copper link, then ends with a discussion on what you’ll need to simply verify the Ethernet performance of a cable run. collapse
An optical time-domain reflectometer, or OTDR,
is an instrument used to analyze optical fiber. It sends a series of light pulses into the fiber under test and analyzes the light... more/see it nowthat is scattered and reflected back. These reflections are caused by faults such as breaks, splices, connectors, and adapters along the length of the fiber. The OTDR is able to estimate the overall length, attenuation or loss, and distance to faults. It’s also able to “see” past many of these “events” and display the results. The user is then able to see all the events along the length of the fiber run.
However, OTDRs do have a weakness?—?a blind spot that prevents them from seeing faults in the beginning of the fiber cable under test. To compensate for this, fiber launch boxes are used. Launch boxes come in predetermined lengths and connector types. These lengths of fiber enable you to compensate for this blind spot and analyze the length of fiber without missing any faults that may be in the first 10–30 meters of the cable.
An optical break locator, or OBL, is a simplified version of an OTDR. It’s able to detect high-loss events in the fiber such as breaks and determine the distance to the break. OBLs are much simpler to use than an OTDR and require no special training. However, there are limitations. They can only see to the first fault or event and do not display information on the portion of fiber after this event. collapse
