Fiber Acceptance Test Kit
23005
-
The unique design of the splice accommodates either 125um or 140um fiber and any size buffer up to 900um. The precision made splice holder firmly holds the pigtail in position without causing stress on the fiber. The low viscosity index matching liquid has an indefinite shelf life and allows for an easy glide of the bare fiber into the splice. Within seconds, a fiber acceptance reading can be made with an OTDR or test set. Low loss with minimum back reflection can easily be achieved for more accurate signatures. Other applications for this kit: splice training aids, bare fiber adapters, and temporary splicing.

Optical Fiber Cable Testing Equipment
-
Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.

Circulator And Isolator
-
A circulator is a three-port passive RF device that directs signals to flow in a single direction, like a one-way street for radio frequencies. An isolator is a type of circulator with one port terminated in a matched load, effectively acting as a two-port device that only allows signals to pass through in one direction and protects components by dissipating any reflected signal.

To protect a power amplifier in case of bad antenna matching the use of a circulator is recommended. This item conducts the reflected power into an external terminating resistor where it is absorbed. Therefore the power amplifier is protected well because the output stage is always matched correctly.
