During the production and installation of MTP and MPO cables, it’s necessary to verify continuity and polarity on these cables. The OP-Polarity Kit makes it a simple task. The OptoTest Polarity Kit consists of an OP280, which acts as a source module, and an OP480, which acts as a detector module, and a set of […]
AN-135 Launch Conditions for Multimode Testing Overview An LED light source is required per IEC 61300-3-4 for testing insertion loss on multimode cabling/connectors. When LASER sources are used, outside influences, such as movement and settling in cable as well as changes in temperature, can cause output power instability which can affect insertion loss test results. Controlling launch […]
AN-128 Ensuring Accurate Return Loss Measurement Overview As fiber optic networks move towards higher data rates and lower loss, connectors with increased performance (low insertion and return loss) have become the standard. Return loss requirements on connectors have begun to approach the physical limitations of the polishing process and, as such, any error in the […]
OptoTest is currently in the process of innovating to improve the usability of its Single Channel OP940 Insertion and Return Loss Test Set. This latest development will integrate completely with the OP940, expanding its functionality beyond its existing capabilities.
OptoTest takes part in establishing the first production line of fiber optic cable assemblies in Angola. We would like to wish Fiberway the best of luck as they begin production and we would like to thank our distributor Fiberlab for allowing us to be a part of this groundbreaking project.
AN-112 Testing Insertion Loss and Return Loss on Ribbon Fiber Fanouts with OPL-MAX Overview Measuring Insertion Loss and Return Loss on Ribbon Fiber Fanouts, like the MTP® to LC cable shown in figure 1 below, can be a streamlined process when using the right equipment and automation software. For the methods described in this Application Note, […]
OptoTest Standards Cheat Sheet Insertion Loss Measurement Procedures FOTP-171 Being rewritten to define encircled flux as a launch condition requirement on certain measurements Method A: Single cable reference Method B: Two cable method, with a recommendation to measure multimode cabling in two directions by swapping the ends Method C: Replacement method (golden cable) for hybrid cable […]
AN-140 SRL Testing for APC Terminated Cables using the OP940 Front Panel Overview The OP940 was designed as an upgrade to the existing OP930 product line. One of the many additional features is the ability to reference to an angle polished connector through the front panel of the unit. The new feature works by searching for […]
