Recommendations for High-speed Fiber Optic cable
Recent years, with the developments of 10g transceiver modules, there is a low cost technical solution in the short distance high speed internet connections, it is gigabit high speed cable. These direct attach cables also known as twinax cable, they are different from other common fiber optic cable, whether in the application or their appearances. They increase reliability of short 10 Gigabit network connections. In order to satisfy data meter and high performance computing application needs for a high density cabling interconnect system capable of 10Gb/s per channel transmission rates, （shown as the figure）we can find that they are designed to be fully compatible with optical or electrical connections in the factor of shape and industrial standards, sfp+ dac meet the harshest external operating conditions including temperature, humidity and EMI interference. Here I will introduce several popular SFP cables simply.
First, passive sfp+ cable, standard?sfp+ copper transceiver module? Assemblies are offered in different wire gauges (AWG) depending on length. fiber-mart’s SFP+ direct attach copper cable assemblies are a high speed, cost effective alternative to fiber optics in 10Gb Ethernet, 8Gb Fibre Channel and InfiniBand applications. SFP+ copper cable assemblies enable hardware OEMs and data center operators to achieve high port density and convertibility at a low cost and reduced power requirement. They are used to low power consumption to assist in making the passive copper cable assembly on economic solution for within rack, or rack to rack applications, but as for the type, i summarised three points:
Copper typical maximum length recommended at 15 metersExcept this, the new 3m active optical cable in fiber-mart also widely used, just sfp 10g aoc3m. They are usually for QSFP+ to SFP+ applications compliments, its highlights are that they using industry Using industry leading VCSEL technology, an advanced new light-engine design and bend insensitive multimode fiber, this AOC delivers exceptional cost and performance value for 10 and 40GbE applications at distances of up to 100 meters.
Finally the common sfp+ cable, also the most popular products in our fiber-mart, Cisco Compatible SFP+ Twinax Copper Cables, sfp+ direct attached twinax copper?(DAC’s) are programmed specifically to work with Cisco equipment. When these cables are plugged into Cisco equipment they will not trigger the error message that a non-Cisco transceiver has been detected. These cables do not violate Cisco’s warranty. Well, i just think it is quite important for users. So you can buy it safety from fiber-mart.
