Why Choose QSFP28 Transceivers for 100G Transmission? 1

Why Choose QSFP28 Transceivers for 100G Transmission?

Over the years, there has been an unprecedented increase in network connectivity and bandwidth needed to accommodate workload requirements of cloud computing, and high-performance web services. The rapid advancements in fiber optic technology has enabled easy upgrading from 10GbE to 40/100GbE within the data centers. With the emergence of 100GbE technologies, the creation of data center network architectures free from bandwidth constraints has been made possible. Among 100G interconnect components, QSFP28 transceiver is the predominant form factor for 100G switching and routing connectivity, a key enabler as 100G begins to ramp in data centers.

Nepal Telecom Deploys Fiber Optic Cable from Kathmandu to China Border 3

Nepal Telecom Deploys Fiber Optic Cable from Kathmandu to China Border

The Himalayan State , Nepal’s incumbent telecom operator Nepal Telecom (NT) has finished deployment of fiber optic cables from the capital Kathmandu to the Rasuwagadi border area near China in an attempt to boost communication services between the two countries. There is considerable growth in communication services between two countries recently. Newly installed fiber optic cables will further connected to the cables coming from China to have an across the border connectivity.

Patch Cable Selection Guide to Fiber Optic Transceivers

Nowadays, a huge number of bandwidth-hunger devices are housed in data centers, like clustered storage systems, backup devices, and various servers, which are all connected by networking equipment. These devices need reliable and scalable cabling structure for high performance and flexibility. For some large- or middle-sized enterprises, their billion-dollar business lie in the suitable deployment of fiber patch cords and fiber optic transceivers. Since there are many kinds of patch cables available in the market for transceiver modules to promote data transmission in enterprises’ data centers, it seems a little difficult to choose the right kind for such transceivers. This text tackles this issue and provides some selection guide.

Light From Optical Fibers Can Induce Sound Waves

Researchers have developed a promising new fiber-optic based chemical sensing method that uses light inside a fiber to induce sound waves outside it, providing indirect information about what surrounds the fiber. By overcoming a significant limitation of existing sensors, the new method could improve sensing capabilities for a wide range of applications, including industrial processes and remote detection of chemicals.

Investigators Raid NetCity Office in Romania

Regulation and control is the mantra now for telecom regulators worldwide. Romania’s Anti-trust agency, Competition Council has initiated a series of investigation to probe the NetCity Telecom’s policies that the regular says is discriminatory. It is alleged that the NetCity, which operates the Bucharest’s underground fiber optic networks had established a dominant position and implemented restrictions that make sharing of the network difficult.

Fiber Light Loss: What Causes it & How to Fix it? 7

Fiber Light Loss: What Causes it & How to Fix it?

As one of the most effective approaches today for reliable and long-distance communications, fiber optic cable has attracted network designers’ notice while they take on cabling installation and upgrade projects. Undoubtedly, compared with copper, fiber optic cable delivers more bandwidth, and allows for more reliable data transmission over longer distance, say 10km distance is possible in GbE applications when used in combination with 1000BASE-LX SFP transceivers (EX-SFP-1GE-LX). To put it simply, fiber is able to carry more information with greater fidelity since finer is immune to many environmental factors that affect copper wire. However, there are many aspects that may influence the performance of fiber, such as light loss, a key issue. And such fiber light loss seems to be a top priority for network designers to consider while handling fiber optic cable. This article mainly discusses problems that cause loss and methods to fix it.
