What is a high-speed cable? What are the benefits of using a high-speed cable?
High-speed cable as a replacement optical module low-cost short-range connection program, widely used in SATA storage devices, RADI system scenarios, core routers, 10G or 40G Ethernet and other data center interconnection scenarios. What is a high-speed cable? What are the benefits of using high-speed cables?
What is a high-speed cable?
High-speed cable (Direct Attach Cable, referred to as DAC) is usually a fixed length of procurement, with a fixed connector at both ends of the cable assembly. The connector used at the high-speed cable end is the same as the interface of the optical module, but the connector module on the high-speed cable does not have expensive optical lasers and other electronic components compared to optical modules, resulting in significant savings in short-range applications Cost, and power consumption, as a low-cost, high-speed, high-speed data communications solution for alternative optical modules, can be used in storage area networks, data centers, and high-performance computer connections by connecting switches to routers or servers.
What is the structure of the high-speed cable?
To silver-plated conductor and foam insulated core for the material, the use of wire-to-shield and the total shielding mode, which constitutes a high-speed cable. High-speed cable with excellent attenuation performance, low latency and anti-jamming, can achieve high-frequency broadband transmission, 30 ~ 24AWG specifications and 2P, 4P or 8P and other structures, can be used in a variety of different applications. These are the common classification of high-speed cable?
1,10G SFP + to SFP + DAC
10G SFP + SFP + DAC is a passive dual-axis cable assembly, and directly connected to the SFP + module, with high density, low power, low cost and low latency characteristics, has become a cloud computing and cloud storage in the mainstream Interconnection tool.
2,40G QSFP + to QSFP + DAC
The 40G QSFP + QSFP + DAC provides a cost-effective way to build a 40G link between the internal rack and the cross-chassis QSFP + switch ports, enabling the access layer to reach the core backbone link to 40G / 100G, With its high speed, low latency characteristics are widely used in high-speed backbone network, enterprise network switching and network storage.
3, 40G QSFP + to 4xSFP + DAC
QSFP + to 4xSFP + DAC is a 40G QSFP + interface, meet SFF-8436 requirements, the other end is four 10G SFP + interface, in line with SFF-8432 requirements, the middle through the 12-core MPO high-density optical cable connection, and then according to customers for both ends Cable length of the demand, in the middle of the MPO cable to join the branch, to achieve all the way 40G optical signal is divided into four 10G signal, is the most economical and simple to achieve switch port conversion.
4,40G QSFP + to 4XFP DAC
40G QSFP + to 4XXFP + DAC is one end of a 40G QSFP + interface, the other end is four 10G XFP interface. As the XFP optical module without DAC copper standard, the device transmission signal compensation is low, the cable itself is very large loss, it can only do short-distance transmission, generally only do less than 2m distance, to achieve 40G QSFP + interface to the XFP port even.
5,25G SFP28 to SFP28 DAC
25G SFP28 to SFP28 DAC provides customers with 25G high bandwidth data interconnection capability, IEEE P802.3by Ethernet standard and SFF-8402 SFP28, are widely used in data center or supercomputing center system scene.
6,100G QSFP28 to QSFP28 DAC
100G QSFP28 to QSFP28 DAC can provide customers with 100G high-bandwidth data interconnection capabilities, providing 4-way duplex channel, per channel operating rate can be supported to 25Gb / s, convergence bandwidth of 100Gb / s, in line with SFF-8436 specification, QSFP28 port between devices.
7,100G QSFP28 to 4 SFP28 DAC
100G QSFP28 to 4 SFP28 DAC One end of the 100G QSFP28 interface, the other end of the four 25G SFP28 interface, can provide customers with 100G high-bandwidth data interconnection capabilities, in line with SFF-8665 / SFF-8679, IEEE 802.3bj and InfinibandEDR standards, Widely used in data center or supercomputing center system scene.
What are the benefits of using high-speed cables?
1, high-performance: for short-distance data center cabling, the use of a wide range of integrated program switching capacity.
2, energy saving: high-speed cable internal material is copper core, the natural cooling effect of copper, energy saving and environmental protection.
3, low power consumption: high-speed cable low power consumption. As the passive cable does not need power, power consumption is almost 0; active cable power consumption is generally about 440mW.
4, low cost: copper prices and fiber is much lower, therefore, the use of high-speed cable can greatly reduce the cost of the entire data center wiring.
High-speed cable with high cost performance, high efficiency, high speed, high composite and low loss and other significant advantages are more and more accepted by users, and become the first choice for high-speed data communications solutions. Rollball provides high-speed cable through a variety of high-quality testing, as well as system solutions can be provided to users, for users to build a more perfect high-speed network system.
