Why Choose PoE Switch for Your Network?

PoE is a technology which enables electrical power to pass over Ethernet cable at distances up to 100m. It is developed to reduce the cost of network planning, cabling and installation. PoE is primarily used for low-powered terminal devices, typically VoIP phones, IP cameras and wireless access points, but it can also provide a redundant power supply for switches to increase the network’s reliability. Until recently, the PoE switches are commonly found in industrial Ethernet network deployments. 802.3af and 802.3at PoE Standards The IEEE is responsible for creating PoE standards….

Huawei Marine and Tele Greenland Join Hands to Deploy 100G Network

Huawei Marine joins hands with Tele Greenland for the deployment of a 100G network along the Greenlandic Westcoast. The new coalition will also upgrade the capacity of existing Greenland Connect fiber optic cable, which connects Greenland with Iceland/Europe and North America. Huawei says once the new project is completed, the submarine system would be the world’s first 100G submarine network in the norther hemisphere. Greenland is located between the Arctic and Atlantic Oceans with 80% of the island covered by ice and snow year round. Huawei Marine will supply the…

Laser Diodes in Fiber Optic Communication

Laser is an abbreviated form of ”Light Amplification by the Stimulated Emission of Radiation”. A laser is a device that produces optical radiation by the process of optical amplification based on the stimulated emission of electromagnetic readiation. Laser was developed in 1960. Invention of Laser is one of the major milestones in the history of fiber optic communication. Theodore H. Maiman at Hughes Laboratory invented the first Laser, based on teh theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A Laser emits coherent light and this is the…
