Categorias de cabos Ethernet explicadas: Uma breve história

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.

Como testar um transceptor SFP e um cabo de rede

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.

Fibra vs. Cobre até a borda: Por que a fibra é uma escolha crescente para edifícios inteligentes e sustentáveis

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.

Os seus cabos de fibra óptica e testadores estão prontos para a Ethernet 400G?

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.
