by Fiber-MART.COM Fiber Optic Fusion splicer  may be the act of joining two optical fibers end-to-end using heat. The thing is to fuse both the fibers together in such a way that light passing with the fibers is not scattered or reflected back from the splice, and thus the splice as well as the region surrounding it are almost as strong because virgin fiber itself. The basic fusion splicer apparatus includes two fixtures which the fibers are mounted and two electrodes. Inspection microscope assists in the placement in the prepared fiber ends into a fusion-splicing apparatus. The fibers they fit in to the apparatus, aligned, and then fused together. Initially, fusion splicing used nichrome wire as the heating unit to melt or fuse fibers together. New fusion-splicing techniques have replaced the nichrome wire with fractional co2 (CO2) lasers, electric arcs, or gas flames to heat the fiber ends, causing them to fuse together. The little size of the fusion splice along with the deve...

by Fiber-MART.COM Fiber Optical Identifier  is an essential installation and maintenance instrument which can identify the optical fiber by detecting the optical signals transmitted through the cables, during this process the fiber optic identifier do no harm or damage to the fiber cable and it also don’t need opening the fiber at the splice point for identification or interrupting the service.During fiber optic network installation, maintenance, or restoration, it is also often necessary to identify a specific fiber without disrupting live service.   The Fiber optic identifier have a slot on the top. The fiber under test is inserted into the slot, then the fiber identifier performs a macro-bend on the fiber. The macro-bend makes some light leak out from the fiber and the optical sensor detects it. The detector can detect both the presence of the light and the direction of light.   A fiber optic identifier can detect “no signal”, “tone” or “traffic” and it also...

by Fiber-MART.COM Though fiber optic cabling is in full swing in recent years, it still can not take the place of the copper cabling completely. As one type of the copper cabling, Unshielded Twisted Pair (UTP) cable is most certainly by far the most popular cable around the world. Because UTP cables are used not only for networking but also for the in television, video, and telephone applications. When we talking UTP cables, we’ll likely come across Cat 5, Cat 5e, and Cat 6 cables with no clue as to what these designations mean. Why are they called as Cat with a number? Are these cables the tails of felines, and the number denotes how many of their nine lives remain? Of course, it is just a joke for the outsider. Cat here is short for “category”, and the number, such as 3, 5, 5e, 6 etc., refers to the generation of twisted pair Ethernet technology. Though it is said that the Cat 5 cable is the most popular of all UTP cables in use today, many new generation of UTP cables still come...

by Fiber-MART.COM In  fiber optic network , whether installing new cable, or troubleshooting existing cable, cable testing always plays an important role in the process. Optical power meter which is widely used for power measurement and loss testing is well known to us. Today, we are going to talk about this familiar and essential fiber optic tester—optical power meter, in details.   As its name suggests, optical power meter is a meter which is used for testing optical power. So, what is optical power? And how to measure power by using optical power meter?   Optical Power In simple terms, optical power is the brightness or “intensity” of light. In optical networking, optical power is measured in “dBm” which refers to a decibel relative to 1 milliwatt (mW) of power. Thus a source with a power level of 0 dBm has a power of 1 mW. Likewise, 3 dBm is 2 mW and -3 dBm is 0.5 mW, etc. And one more thing should be known is that 0 mW is negative infinity dBm.   ...
