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 […]
Can you count on your test equipment to get the job done now and for the long haul?
As fiber continues to replace copper and as emerging technologies demand the deployment of more fiber that meets ever higher performance requirements, the need for fast and accurate testing of fiber optic cables is more important than ever before. What is not discussed nearly as much is the longevity of the equipment used for testing, […]
Why upgrade your OP930 to OP940? When is the right time to upgrade?
The OP930 served as the premier option for IL and RL testing in both lab and production settings for over 10 years. In 2016, the final OP930 was produced and the OP940 made its debut. The OP940 insertion loss and return loss meter was designed with the same technology principles as the OP930 and introduced […]
Industry Update – Effects of Using a BIMMF Cable as a Launch Cord
The TIA convened for its last meeting of 2019 from Sept 16th to Sept 20th in Albuquerque, New Mexico. Up for discussion in the TR42.11 subcommittee was the general concern from field installers on the testing and usage of bend insensitive multimode fiber (BIMMF). Current standards call for non-BIMMF cables to be used as the […]
OptoTest Releases New Adapters for Integrating Sphere
OptoTest is pleased to announce the release of new adapters for testing duplex LC (including unibody), 16f MTP, and CS connectors. With these adapters, insertion loss and return loss are tested across all fibers of the connectors without the need to move or slide the adapter. The new adapters were designed for the OP-SPHR Integrating […]
How Can You Accurately Test Performance of Hybrid Cables?
Hybrid Cable – Simplex Hybrid Cable Solution Sheet SOL-001Rev.A Fiber patch cables, also known as patch cord or jumper cables, are fiber optic cables that are terminated with connectors on both ends. When the connector types on each end are different, the cable is aptly dubbed a HYBRID CABLE. These hybrid cables can serve […]
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 […]
Bidirectional IL/RL Test on a Duplex-LC Cable
The OP940 and OP721 form the ideal test system for multichannel bidirectional insertion loss and return loss testing. The increased demand for more efficient IL and RL testing on multifiber cables, such as duplex LCs, MTP cables, and MTP fanout cables has led to an increased interest in this type of measurement. Additionally, this type […]
