Wavelength Division Multiplexing (WDM) is a technology that increases the data-carrying capacity of optical fiber by allowing multiple streams of data to be transported using different wavelengths of light. The primary benefit of WDM technology is that it requires just a single optical fiber which, in most cases, has already been deployed. Therefore, it is a much less expensive option for expanding network capacity compared to installing additional fiber cables.
The introduction of 200µm coated fibers in the market has introduced a paradigm shift in cable and splicing technology. These smaller fibers are readily found in loose fiber cables, and compared to a standard 250µm loose fiber cables, the positives are unmet by any significant negatives from the customer’s viewpoint. The only real disadvantage is that currently most 200µm fiber applications can only be spliced one fiber at a time. The reason for single fiber splicing is, that when looking at the fiber, the difference is minute. The untouched fiber has shrunk by 50µm, and when the coating is stripped away, it is still 125µm glass.
A vertical-cavity surface-emitting laser (VCSEL) is a semiconductor-based laser diode that emits a highly efficient optical beam vertically from its top surface. VCSELs differ from other common semiconductor optical sources such as Edge Emitting Lasers (EEL) that emit light from the side and Light Emitting Diodes (LED) that emit light from all directions. VCSELs technology brings together the advantages of low cost and optical efficiency within a small footprint.
It may be difficult to manage the explosive growth in network systems integrated into the enterprise LAN along with the ubiquitous use of smartphones and mobile apps. But, on the plus side, the diversity of connected devices and systems gives us more tools than ever when it comes to safeguarding lives and property. In an emergency, in-building wireless enables those who are trapped or endangered to call for help; security cameras can identify and locate intruders; and environmental sensors alert building occupants at the first signs of fire.
Legrand has introduced a new line of single-phase power products that include LP-Series Power Distribution Units (PDU) and LU-Series Uninterruptible Power Supplies (UPS) to serve the growing demand of edge and IoT applications in the North and Central America regions. The line was built to support network installations in network closets, data centers, retail applications and commercial environments.
This webinar explores the considerations that data center operators must make when planning the 40G-to-400G transition, from the standpoints of optical-networking capabilities and cable-management strategies. It describes how data center managers can increase asset utilization, reducing the complexity of jumper-cable deployment and eliminating stranded or unused fibers. It also details cable-management approaches that can both support high-density fiber installations and ease the process of network changes when they are necessary.
More than half of Industrial Ethernet problems can be traced to cabling. Some of these show up immediately during the startup process – others can allow the connection to function properly until something such as environmental changes cause communications failures. Ethernet is a robust technology that allows communications to continue even under marginal circumstances – but a change in those circumstances might cause communications problems or a complete failure down the road. Here are the most common problems with cabling.
AFL has introduced the FOCIS Lightning Ultrafast MPO/MTP connector inspection system with twin 5M pixel CMOS sensors to image the entire MPO end face simultaneously and perform multi-fiber inspections 10 to 100 times faster than legacy systems. This full view connector end face image is displayed in less than two seconds from power-on—a capability unique in the industry.
Learn about the different form-factors, transceivers and modules available for 100Gb Ethernet on Cisco devices. There are many different types of 100Gb Ethernet transceivers. Each has its own functional mode.
The release of purpose-built MPO test solutions has become a game changer for many contractors, giving them the ability to efficiently install and test MPO networks. With tools that are purpose-built for testing MPO, technicians can streamline their test workflows to reduce test time by up to 80%. In addition to time savings, the test process is greatly simplified, as technicians are no longer forced to deal with the complexities of breakout cables and the added steps involved when referencing and testing with devices that were built for single or duplex fiber connections.
