Faster Networks Demand More Accurate Measurements

Today’s high-tech data centers form the digital heart of communication and commerce in our world. But every industry has its “remember when” stories, and World Metrology Day is a perfect time to tell them.

Ethernet Cable Categories Explained: A Brief History

Millennials who entered the workforce between 2003 and 2016 are accustomed to the digital era: high-speed internet access, smartphones, online everything. And while they’ve definitely experienced advancements in technology during their lifetime, they may not be aware of just how far copper Ethernet cabling has come to make it all possible. We thought we’d start off 2022 with a little Ethernet history lesson for the younger generation and a walk down memory lane for those of us that have been in the industry a bit longer than we’d like to admit.

How to Test an SFP Transceiver and Network Cable

Recently we have been getting questions about how to determine if an SFP (Small Form-factor Pluggable) transceiver is working. We refer to SFP generically here to represent a multitude of the various optical modules that are available. Fluke Networks fiber testers can be used to measure the light that is being put out by an SFP.

Choosing the Best Fiber Optic Scope for Today’s Fiber Inspection

Contaminated connections remain the number one cause of fiber related problems and failures in data centers, campus, and other enterprise or telecom networking environments. But it’s not enough to just clean every fiber end face—there is no way to know if the end face is clean unless you inspect it.

Fiber vs. Copper to the Edge: Why Fiber is a Growing Choice for Smart, Sustainable Buildings

For years, we’ve heard about FTTX making its way into the horizontal LAN—fiber to the desktop, fiber to the office, fiber to the enclosure, fiber to the zone, etc. Often referred to as “fiber to the edge” or FTTE, most of these deployments have traditionally been for high-security government environments or specialty applications or devices. Now, as bandwidth requirements continue to increase and the commercial real estate industry is trending towards smarter and more sustainable buildings, the question of using fiber vs. copper is more relevant.

광케이블 및 테스터가 400G 이더넷을 사용할 준비가 되어 있습니까?

Driven by large hyperscale and cloud data center providers, advancements in signaling and transceiver technology have led to the development of next-generation transmission speeds. There are now multiple options available for 400G Ethernet applications over multimode and single-mode fiber with more on the horizon. And it doesn’t stop there—big players like Google, Facebook, and Microsoft are driving innovation to support 800 Gig and 1.6 Terabit applications, and the IEEE Beyond 400 Gig Ethernet Study Group is already defining objectives.

What is Insertion Loss?

Insertion loss is the amount of energy that a signal loses as it travels along a cable link. It is a natural phenomenon that occurs for any type of transmission—whether it's electricity or data. This reduction of signal, also called attenuation, is directly related to the length of a cable—the longer the cable, the greater the insertion loss. Insertion loss is also caused by any connection points along a cable link (i.e., connectors and splices).

금속 LC 커넥터: 래치 파손의 우려가 없는 광케이블 테스트 참조 코드

사용 중인 구성 요소의 유형에 따라 다양한 유형의 광 커넥터가 있지만, 네트워킹 산업 전체에 걸쳐 LC 커넥터가 매우 흔해졌습니다.

플라스틱 LC 커넥터

연결부에 플라스틱을 사용하는 경우 플러그를 꽂은 다음 거의 건드리지만 않으면 완벽하게 작동합니다. 하지만 예를 들어 광케이블 테스트 참조 코드를 사용하여 이러한 연결을 반복적으로 수행하고 분리해야 하는 경우, 반복적인 구부림으로 인해 하우징의 신축성 래치가 파손되는 경우가 많습니다.
