Testes e padrões estruturados de cabeamento - Harmonização

If you ever attended a Standards meeting you might have heard the word “harmonization” mentioned frequently. The idea of harmonization, somewhat of a holy grail, is to have standards from different organizations agree. For example, imagine if the TIA, IEC, and ISO/IEC organizations used the same test standard. Actually, there is nothing to stop them – TIA frequently adopts IEC standards. However, I am not aware of IEC or ISO/IEC adopting a TIA standard.

Série 101: Multimode vs. Monomodo

Fiber optic cabling comes in two types – multimode and singlemode. Most of you likely know that multimode cabling distances are shorter than singlemode, and singlemode is therefore deployed for outside plant long-haul fiber applications, while multimode is the primary choice for data centers and premise applications.

Melhores práticas de rotulagem de cabos, Circa 2017

For professional contractors and installers of data communications cabling systems, compliance with ANSI/TIA 606-B Standards updated back in 2012 has required new levels of precision in cable labeling – often an arduous and time-consuming process for cable installers. Today, however, thanks to smart, cutting-edge cable labeling tools and technologies, that situation has improved dramatically!

606-B Compliance…and a Whole Lot More

Em testes bi-direcionais, com uma fonte de luz e medidor de energia

In the 2014 version of ISO/IEC 14763-3, testing of optical fiber cabling, unidirectional testing for permanent links is required. In specific cases, bi-directional testing is required. However, ISO/IEC 14763-3 provides no information on how a bi-directional test should be done - this article explains how.

When Bi-Directional Testing is Required

No posicionamento do cursor ao fazer uma medição OTDR

Testing and characterizing a permanent link with an OTDR requires the measurement of connector attenuations A/B and fiber loss C. To make this measurement, a launch and tail cord are needed (see Figure 1).

Série 101: O que é diferente sobre TRCs e como faço para escolher um?

While it may look and feel like a fiber patch cord, Test Reference Cords, or TRCs for short, are not patch cords. There’s a little something different about these cords that are used for certifying fiber cabling systems to ANSI/TIA, ISO/IEC and IEEE standards.

Todas as rotas de fibra divisíveis por 2 e 8

By now you’ve probably heard of 8-fiber MPO plug and play solutions available on the market, which are ideal for Gigabit (40GBASE-SR4) and 100 Gigabit (100GBASE-SR4) applications that use 8 fibers with 4 transmitting and 4 receiving at either 10 or 25 Gb/s.

Future of fiber application is divisible by 2 or 8Unlike 12-fiber MPO solutions where 4 of the 12 fibers go unused, 8-fiber MPO solutions offer 100% fiber utilization in these applications.
