To meet the growing demand for high-speed transmission, data centers are migrating from 10G networks to 40G or even 100G networks. During this period, users first need to consider cost factors, and Direct Attach Cable is a highly cost-effective solution for migrating to 40G or 100G network applications.
What is a high-speed cable?
Direct Attach Cable, also known as DAC, consists of fixed components that can be used to support high-speed data transmission. Each end is equipped with a fiber optic transceiver for transmitting signals. High speed cables, with their significant cost advantages and energy-saving advantages, are widely used in short distance data transmission. They can be connected to switches, servers, routers, network interface cards (NICs), and host bus adapters (HBAs), providing high-density and high data processing functions for network transmission.
Why choose high-speed cables?
High speed cables have many significant advantages and can meet the growing demand for high data transmission. The following will list the main advantages of high-speed cables for you.
1, Cost advantage: The Transceivers on high-speed cables are not truly optical modules, they do not come with components and can only transmit signals. These connection modules do not have expensive electronic components such as lasers, which is the main reason why high-speed cables are cheaper than optical modules. In some cases, high-speed cables can replace optical modules to eliminate separable interfaces between optical modules and cables. Therefore, in some cases, choosing high-speed cables can save a lot of time and money.
2, Low power consumption: In order to identify the type of cable from the two end modules to the Ethernet interface, the small electrical components in active high-speed cables and passive high-speed cables play a huge role, and have many advantages such as low cost and low power compared to optical modules.
3, Support for high data rate: High speed cables can provide high-speed I/O (input/output) data transmission function. The most commonly used high-speed cables can support 10Gb/s and 40Gb/s data transmission.
4, Meets miniaturization standards: Each end of the optical module on the high-speed cable meets miniaturization standards, which means that the high-speed cable inherits some of the advantages of miniaturized optical modules, such as space saving.
Due to its strong data transmission capability and numerous advantages such as low cost, high-speed cables have become increasingly popular in short distance transmission (ToR) and medium distance transmission (MoR) data center network applications, providing users with an economical and effective solution in 40G/100G network migration applications. At present, high-speed cables are constantly developing to meet the different needs of different industries.
