W/D S/S BY TIA-455-62

This test method describes procedures to determine the bending loss ofuncabled graded-index multimode or single-mode fiber.The applicabilityto step-index fiber may require different conditions in 3.2 to 3.4, andin 6.5.Various bend radii and numbers of turns can be accommodated.

This test can be used to compare the bend performance of differentfibers at various wavelengths.Its purpose is to help characterizefiber performance in bend configurations such as in fiber routing withinequipment racks, or bending of excess fiber within splice housings.Itmay also indicate relative fiber performance affected by cablingcurvature lays and in cable routings.

The test is performed on uncabled fiber only, although the results maybe useful in predicting fiber performance in cables or pigtails.

Either of two methods (or both) are permitted by the test procedure, asspecified in the Detail Specification.

Method A measures the increase in the fiber attenuation due to a changefrom the straight condition to a bent condition.This is suggested fora smaller number of turns and/or larger bend radii.

Method B measures the total attenuation of the fiber in the bentcondition.This is suggested for a larger number of turns and/orsmaller bend radii.

If both Method A and Method B are used, an optional calculation can be
