Fiber Optic Bend Radius Calculator

Fiber Optic Bend Radius Calculator. Feel free to download the table reference for your use. Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life.

When the manufacturer has failed to do this, you can go by this general rule of thumb: In absence of manufacturer stated rules, the generic guidance is four times (4x) the cable jacket diameter for u/utp ethernet cable or eight times (8x) for f/utp (and sf/ftp) solid copper structure cable. The manufacturer should specify the minimum radius that your cable may safely be bent.

20 Times Of Outside Diameter (O.d.)


This calculator can be used to estimate the maximum stress associated with fiber in bending. Outputs the radius of the effective gaussian. Some cables have different specifications, e.g.

R Minimum Bend Radius, In Meters (M) E Young’s Modulus (70,000 N/M2) R Fiber Clad Radius, In Meters (M)


The manufacturer should specify the minimum radius that your cable may safely be bent. This includes pulling tension, minimum bend radius or diameter and crush loads. Enter in these first 4 parameters which describe the properties of the optical fiber.

For example, a 6 strand indoor fiber optic cable if pulled too hard around a tight 90 may appear to be fine once the cable pull is finished. A2 and g.657.b1 fibers is 7.5mm and of the g.657.b2 fibers is 5mm. The minimum bend radius is the smallest allowable radius for a given fiber optic cable to be bent around.

Unfortunately, What Commonly Happens Is The Stress Around That 90 Caused The Individual Strands To Break Under The Jacket.


All fiber optic cables have specifications that must not be exceeded during and after installation to prevent irreparable damage to the cable. Feel free to download the table reference for your use. When a fiber cable is bent excessively, the optical signal within the cable may refract and escape through the fiber cladding.

Use it to your advantage but be careful to understand and follow best practices are. So if you’re dealing with a fiber cable that has a 2mm outer jacket, then 2mm x 10 = 20mm bend radius. The optical minimum bend radius is equal to ten times the outer jacket diameter of that cable.
