What’s an Expanded Beam Fiber Connector?

In the premises and data center infrastructure world, most of us are familiar with typical fiber connectors like duplex LC, SC and ST connectors and multi-fiber MPOs. Perhaps you’ve also heard about expanded beam fiber connectors or have encountered a scenario that requires them.

In case you aren’t familiar with these connectors, their applications and testing considerations, we thought we’d help you “expand” your knowledge.

Fiber Certification Testing: All You Really Need is Loss, Length (and Sometimes Reflectance)

As data speeds increase and new fiber applications emerge, there has been some confusion surrounding fiber testing parameters and whether insertion loss testing is enough to guarantee support for high-speed applications.

Other than new short-reach singlemode applications that are more susceptible to reflections and therefore take connector reflectance into consideration, insertion loss testing, length and polarity are really all you need for Tier 1 certification testing.

Considerations for Using Hybrid Copper-Fiber Cable

In a previous blog, we covered what to do when you need to connect a device that is located beyond the 100-meter distance requirement and described four ways to address the problem—a new TR, the use of an extender device, extended-reach copper cable and fiber.

End of Year Reflections

When Winston Churchill said that the holiday season is not only one of rejoicing but also of reflection, he didn’t know that 2020 would be the year that family gatherings are kept to a minimum and parties take place over Zoom and FaceTime.

Is Power over Ethernet Safe?

Power over Ethernet (PoE) has been around now for several years, starting with Type 1 PoE (IEEE 802.3af) introduced in 2003 that delivers up to 15.4 W, with 13 W available for the device. That was followed by Type 2 PoE (sometimes referred to as PoE Plus) that delivers up to 30 W, with 25.5 W available for the device.

Keep it Clean: From the Endface to Your Tester

Cleanliness has long been a best practice in fiber optic installation, but since the onset of the COVID-19 pandemic, it’s no longer just the fiber endfaces you need to worry about. If you think about how often your cabling tools and testers are touched by you and others on the job site, it’s clear that they too need to be cleaned.

What’s the Difference Between Channel and Component Standards?

When it comes to cabling standards, you’ve probably heard of channel standards and component standards. The two are not one and the same, so we thought it might make sense to explain the difference, why you should care and how they are tested.
