Since the development of 40GBASE-T (IEEE 802.3bq) began a few years ago, most of us believed that the next Ethernet data center speed for twisted-pair copper cabling beyond 10 Gb/s would be 40 Gb/s.

How long are the fiber links you need to test? Is it a short 50-meter multimode data center link, a longer 550-meter backbone, or maybe even a 130-kilometer singlemode link?
With contaminated connections remaining the number one cause of insertion loss and back reflection that inhibits optical transmission and causes havoc with expensive transceivers, it’s vital that fiber end-faces at both ends of a link are visually inspected.

Im Februar haben wir überlegt, ob 2015 das Jahr der Drohnen würde:
Sechs Monate später scheint die Antwort ein klares „Ja“zu sein. Fast-Zusammenstöße zwischen Verkehrsflugzeugen und ferngesteuerten Drohnen machen mit einer alarmierenden Rate weiterhin Schlagzeilen.

The Telecommunications Industry Association (TIA) is committed, by formal consensus, to develop standards for the benefit of industry and is represented by hundreds of companies. While participating companies cooperate to develop standards, each have their commercial business interests to protect. Sometimes, these companies over-reach to meet their business goals. Fortunately, the TIA voting and balloting process works well as a means to check and balance sometimes rogue proposals.

Several published standards describe how to perform attenuation measurements on installed fiber optic cabling. However, no standard exists that provides guidance for testing installed fiber optic cabling terminated with MPO connectors. Currently, a technical report (TR) is being drafted that provides such testing guidance.
