Multimode fiber Profiles: Step Index vs. Graded. What are the difference, advantages, and applications in Industry.
The Importance of Calibration
With any measurement instrument or tool used to qualify product, it is mandatory that the tool or instrument be 100% functional and measure per the appropriate specifications when used. A manufacturer’s calibration can perform both functions. A system inspection and calibration verify that the instrument is functional and that the instrument was and is measuring accurately, while routine maintenance helps to ensure the instrument will continue to function going forward.
While an instrument’s self-calibration or internal calibration is convenient for routine spot checking and verification, it should never replace a full calibration performed by an unbiased and trained professional.
How You Accurately Test Performance of Hybrid Cables Tutorial
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 to link otherwise incompatible infrastructure in existing fiber systems, such as those found in networks or data centers. They can be used to connect newer racks to legacy hardware, in distribution hubs to branch lines from high density panels to the nodes they serve, or to connect between devices from different manufacturers.

Switches, Lossy Components, and the Need for External Reflectance Standards
This article focuses on RL measurement setups that are prone to introducing testing errors. Ways to mitigate these errors are discussed. Some errors are unavoidable; therefore, steps for correcting them out or reducing them are also described here. Continue reading
Industry Update – Visual Inspection Standard
A recent update to IEC 61300-3-35 (Fiber optic connector endface visual and automated inspection) is moving forward with the intention to modernize inspection practices and provide more uniform results industrywide.
The updates aim to accomplish three things:
- Link visual inspection results to optical performance
- Make results more uniform between manual (visual) and automated (software) platforms
- Make results more uniform between different automated platforms
Ensuring Accurate Return Loss Measurements
OptoTest equipment provides the most accurate Return Loss measurements in the industry. In this presentation you will learn more about the elements that make that possible and things to keep in mind to ensure optimal performance.
