Maximizing Return Loss Measurement Accuracy in Test Setups

White Paper Overview With the wide range of fiber optic cables available for deployment (hybrid, multifiber, etc.), the test setups needed to evaluate them have become quite complex. The complexity required to test these cables often introduces additional insertion loss, resulting in uncertainty and erroneous return loss measurements. To ensure measurement accuracy, it is advisable […]

AN-143 Insertion Loss and Return Loss Testing of Short Cables and Assemblies (including TOSA and cassettes)

AN-143 Insertion Loss and Return Loss Testing of Short Cables and Assemblies (including TOSA and cassettes) Overview As fiber optic infrastructure and components are designed more densely and more compactly, patch cords, cassettes, and optical subassembly cables have followed suit by becoming shorter and shorter. These short cables, which can sometimes be just 20cm in [...]

OptoTest offers 24-Fiber Variant of High-Performance Reference Cables 

OptoTest introduces a 24-fiber variant of the MTP®/MPO High Performance Reference Cables (HPR). Like its 12-fiber counterpart and the simplex version, the 24-fiber HPR cable is designed to maximize the accuracy and repeatability of insertion loss and return loss measurements. In order to obtain the best results possible, both your test equipment and reference cables […]

AN-117 Measuring Insertion Loss and Return Loss of Hybrid Cables in OPL-MAX

AN-117 Measuring Insertion Loss and Return Loss of Hybrid Cables in OPL-MAX

AN-117 Measuring Insertion Loss and Return Loss of Hybrid Cables in OPL-MAX Overview Obtaining connector-level insertion loss (IL) and return loss (RL) for hybrid cables is complicated by the different connector types on either end of the cable. Hybrid cables cannot simply be flipped to test the reverse direction when the reference and device under […]
