10 Gigabit Ethernet or 10GbE is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. Nowadays, 10 Gigabit Ethernet is gaining broader deployments by the increasing bandwidth requirements and the growth of enterprise applications. In the world of 10 Gigabit Ethernet, selecting the appropriate 10-gigabit physical media is a challenge, because 10GbE is offered in two broad categories: optical and copper. This article will introduce both optical and copper cabling options for 10 Gigabit Ethernet.

Fiber Optical Cabling

Single-mode fiber (SMF), typically with an optical core of approximately 9 μm (microns), has lower modal dispersion than multimode fiber. It is able to support...

The Cisco10GBASE SFP+ modules is one of the most popular kinds of transceivers which offers customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.

Main features of Cisco 10GBASE SFP+ modules include: it has the smallest 10G form factor ,hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch and optical inter operability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link. What;s more, it supports not only 10GBASE Ethernet and OTU2/OTU2e, “pay-as-you-populate” model, digital optical monitoring capability, but also the Cisco quality identification (ID) feature that enables a...

With the demand for improved bandwidth, greater flexibility, infrastructure simplification, ease of migration, 10GBASE-T specification was lauched as a cost-effective solution to reach the majority of switches and servers in the data center. This article looks at what is driving choices for deploying 10 GbE and how 10GBASE-T will lead to broader deployment. It also compares 10GBASE-T with other media options for 10 Gb Ethernet.

What Is 10GBASE-T

10GBASE-T is an IEEE 802.3an standard which supports the creation of technology that is capable of transmitting 10 Gigabit Ethernet up to 100 meters over four pairs of CAT-5 balanced copper cabling system. It is an exciting technology that provides end users with cost-effective media to...

From the origin of 10G Ethernet, optical transceivers have been developed along the way to meet the increasing demand for higher-performance servers, storage and interconnects. SFP+ transceiver is an enhanced version of SFP that supports data rates up to 10 Gbit/s. 10G SFP+ transceiver is a popular industry format supported by many network component vendors. In comparison to earlier XENPAK or XFP module, SFP+ transceiver is more compact and leaves more circuitry to be implemented on the host board instead of inside the module. This article will introduce the 10GbE optical standards and the most common types of 10G SFP+ transceivers.

10GBASE-SR and 10GBASE-SR Transceiver

SR stands for short reach. 10GBASE-SR is a port type for multi-mode...
