Twinax Direct Attach Cable
The SP10TW SFP+ direct attach copper cable assembly is a low-cost alternative for short reach applications. The design allows for a serial data transmission up to 12Gbps in each direction. Additionally, the copper cable acts as a natural heat sink. The low power consumption assists in making the passive copper cable assembly an economic solution for within rack or rack-to-rack applications.
These copper cables, known as "direct attach" or "Twinax," connect from one SFP+ slot to another without the need for SFP+ transceivers. This is an economical solution for making short 10 Gigabit connections between products and most servers, network switches and monitoring equipment that have SFP+ slots.The direct attach cable is terminated on both ends with mechanical connectors that plug directly into SFP+ slots in the same manner as SFP+ transceiver modules. The one, three and seven meter cables are all passive cables. They do not have signal buffers or amplifiers.
Low Latency and Low Power
The Twinax cable with SFP+ type of connection is able to transmit at 10 Gigabit full-duplex speed. This setup offers up to 15 - 25 times lower transceiver latency than current 10GbE CAT6/CAT6a/CAT7 cabling systems at 0.1 μs for Twinax with SFP+ versus 1.5 - 2.5 μs for current 10GbE specification. The power draw of Twinax with SFP+ is around 0.1 Watts compared to the typical 4–8 Watts for current 10GbE.
