Sky Optics's SFP+ 10GBASE-T copper transceiver is specially designed for high-speed communication links that require 10GbE over Cat6a/7 cable. This is the first transceiver that offers 10G communication over this type of media. The 10GBASE-T copper SFP+ module Sky Optics offered can convert a 10GbE SFP+ port on a switch or NIC (network interface card) to a 10GBASE-T RJ45 connection, allowing 10G bandwidth over existing copper infrastructure instead of changing to new fiber network equipment. It supports links up to 30 m over Cat6a/7 cable. Compared with an embedded 10GBASE-T RJ45 port for link distances up to 30 m, this module has been optimized to save more than 0.5 W per port.
Some people may ask that with the cheap SFP+ DAC twinax and reliable SFP+ fiber optics available for 10Gbps applications, why should I use the SFP+ copper module? On one hand, in terms of application, some NICs and switches do not work well with DAC twinax. On the other hand, it often easier to use the common RJ45 cables than using the a copper DAC. Though at present the Cat6a/7 cabling provides limited support for 10GBASE-T in some environments, the compelling features of this SFP+ 10GBASE-T copper transceiver make it a favorable choice for long-term consideration. This module has the benefits of backwards compatible and usable for nearly every copper infrastructure, full PHY (physical layer) presentation, and cost-effective for today and future applications.
