Switches, Lossy Components, and the Need for External Reflectance Standards

Share This...

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.

Industry Update – Visual Inspection Standard

Share This...
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:

  1. Link visual inspection results to optical performance
  2. Make results more uniform between manual (visual) and automated (software) platforms
  3. Make results more uniform between different automated platforms

OptoTest will be offering a series of FREE mini-sessions on the topics below at OFC (Tuesday, March 5th through Thursday, March 7th). The sessions will be held at our booth #2538 and will last about 15 minutes. Don’t miss out!

Take the survey below and help us create a schedule for the sessions.

  • Join us as we explore the effect that different launch conditions, including Encircled Flux, have on Insertion Loss and Return Loss testing of multimode cables.
  • OptoTest equipment provides the most accurate Return Loss measurements in the industry. In this session you will learn more about the elements that make that possible and things to keep in mind to ensure optimal performance.
  • In this session we will look at the unique challenges of testing hybrid cables and the different solutions that OptoTest provides for this type of DUT.
  • As the most common and most preventable source of error in fiber optic test systems, come learn the tips and tricks for preventing damage to maintain the performance quality and longevity of optical connectors.

In addition to the group trainings, schedule time with one of our sales engineers to learn more about our product line and determine the fiber optic test solution that is best for you.

Optical Shuffle Polarity Testing

Optical Shuffle Testing with OP415 Polarity Analyzer

How do you Find Flaws in Optical Systems with Multiple Signal Pathways?

As the demand for more information in smaller form factors increases, optical shuffles emerge as a method for maximizing the efficiency of an optical network. Their ability to route signals in many different directions increases the complexity of testing these systems. All possible signal routes must be evaluated for proper signal transmission and quality. Any misrouted fibers in patchcords can cause downtime in networks and identifying those errors early in the production process can reduce the cost of labor required to re-terminate those cables.

TIA torn on OM5 connector color

Share This...
 

The standardization of wide band multimode fiber leads to allocating a color designation similar to the OM2 orange or OM3/OM4 aqua.  The widely accepted color within the Telecommunications Industry Association (TIA) has been lime green for the OM5 cable jacketing.  However, it has been proposed that the connector for OM5 cabling should also be lime green.  On the surface this sounds fitting.

Some concern has been raised among the TIA, pointing out that the lime green designation is too close to standard single mode APC green connectors and could potentially be confused with each other.  Next to one another, an OM5 lime green connector and an APC green connector could most likely be distinguished.  The issue arises when the distinction needs to be made without having the opposing type as a reference.  Basically, in the absence of an APC green connector, it would be difficult to tell if an OM5 lime green connector is lime or green.

Below, you can see the lime green jacket next to the standard APC connectors.
