OP940-SW Multichannel IL & RL Meter

The multichannel OP940 is an internally switched Insertion Loss and Return Loss meter designed for testing ribbon cables and multi-pin termini. This unit incorporates the same features as the single channel OP940 models, including a color LCD screen, an optical reflectance scan mode, programmable PASS/FAIL for user-configurable test criteria, and On-screen context help. It measures […]

AN-137 Preventing Damage to Optical Connectors

AN-137 Preventing Damage to Optical Connectors Effects of Damaged Front Panels Maintaining your equipment’s interface & connectors is absolutely critical to achieving quality results. Damaged instrumentation interfaces and reference cables can add loss and reflections as well as reduce stability, making it difficult to take accurate measurements. In addition to adhering to strict policies regarding cleaning […]

Testing Polarity & Continuity

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

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 […]
