To determine the necessary take-up reel size: Measure the outer diameter (OD) of the cable being respooled, using a calibrated measurement tool such as a band micrometer or dial calipers. Refer to Appendix A which lists the acceptable minimum reel drum size for the measured cable. • Fiber optic cables are often custom cut to match required lengths for each cable run, or you can order a reel matching your total length and cut segments yourself. We advise you to incorporate a safety buffer when ordering. RP Fiber Calculator is a highly convenient software for doing various calculations on optical fibers with radially symmetric refractive index profiles. It has an intuitive graphical user interface with tabs for the following purposes: Your browser does not support the video tag. This advanced reel calculator provides essential metrics for project planning, inventory management, and manufacturing. Diameter of the wire, cable, or thickness of the film/tape.

This calculator uses common Gaussian-mode approximations for coupling into a single-mode fiber. Here, w_f is the fiber mode radius (MFD/2). This article demonstrates how to set up a coupling system and examines the multiple tools available in Sequential Mode for beam and fiber coupling analysis, including Paraxial Gaussian Beam. This tab provides a brief explanation of how we determine several key specifications for our 1x2 couplers. 1x2 couplers are manufactured using the same process as our 2x2 fiber optic couplers, except the second input port is internally terminated using a proprietary method that minimizes back. Compute coupling efficiency for single mode fibers fast. Include offsets, tilt, and waist mismatch today. Beam center offset. Butt coupling is the most basic method of coupling the optical output from a laser diode into an optical fiber. (This functionality is reserved for the PRO version of RP Fiber Calculator.
