Cabling future-ready commercial office buildings

The concept of networking in office buildings evolving from a competitive selling feature to a necessary fourth utility alongside electricity, gas, and water has developed in the last 10 years. The need to enable more instrumentation and control points inside buildings requires wired and wireless networks to connect them back to the services that orchestrate their overall operations. The fourth utility has to span from basement to roof, and from carpeted floors to the parking garage. Cabling infrastructure that is not future-ready will require replacement or augmentation to accommodate the inevitable changes to the attached active electronics over the cabling’s 20-year useful life.

Cable Testing 101: What is the Difference Between OM3 and OM4?

OM3 and OM4 multimode fiber are two common types of fiber used in local area networks–typically in backbone cabling between telecommunications rooms and in the data center between main networking and storage area network (SAN) switches. Both of these fiber types are considered laser-optimized 50/125 multimode fiber, meaning they both have a 50 micron (µm) diameter core and a 125 µm diameter cladding, which is a special coating that prevents light from escaping the core. Both fiber types use the same connectors, the same termination and the same transceivers–vertical-cavity surface emitting lasers (VCSELs) that emit infrared light at 850 nanometers (nm). So, what’s different?

In-Vehicle Optical Multi-Gigabit Communications

The automotive industry is currently seeking technologies to enable 10 Gbps communications. This derives from the growing need for data interchange between sensors and electronic control units in the car. Infotainment, ADAS and growing levels of autonomy are the key trends that explain the exponential growth of data rates: 100 Mbps to 1 Gbps and to 10 Gbps. Some OEMs are even talking about 25 and 50 Gbps for the upcoming years.10GBASE-SR is the current standard by IEEE that establishes a communications channel in optical fiber at 10 Gbps. Although well-established for industrial use, it is not suitable for automotive applications.

AFL receives CPR certification for data center fiber-optic cables

AFL has received Construction Products Regulation (CPR) certification for certain fiber-optic cables including its Sub-Unitized MicroCore 2.0 and MicroCore 3.0, plus its Ruggedized MicroCore, product lines. CPR, often recognized as “CE marked,” defines minimum cable fire safety standard (EuroClasses) based on installation and type of building. Each country sets its own minimum EuroClass requirements for installation cables.

Molex opens optical telecom R&D facility in New Jersey

Molex has opened new research and development facility in Bridgewater, NJ. The building completion represents a significant investment by Molex in the future of optical wavelength solutions for telecommunications networks. The state-of-the-art facility features eco-friendly clean rooms and extensive capabilities for designing and prototype manufacturing of optical solutions for the rapidly emerging segment of metro and long-haul telecommunications networks.

The Beyondtech Guide for Fiber Optics Testing (PART II): Insertion Los

Insertion loss is the ratio of received to inserted signal power at the end of a cable and is dominated by the cable’s attenuation. Measuring Insertion Loss per TIA-568B helps you determine whether a cable’s transmitting capacity has been compromised by poor installation practices such as an inadequate polished or dirty connector or a cable that was installed to go around a corner that didn’t meet the minimum bend radius.
