40G Direct Attach Cable--The Milestone of High-speed Communications Development

In the background of the rapid development of telecommunications industry and network technology, achieving the low-cost and high-efficiency high-speed interconnect solutions has become the driving force for the development of the telecommunications industry. Nowadays, in order to meet the needs of high-speed communication, direct attach cable has become a hot topic of cloud storage, cloud computing, super computer systems etc.Direct Attach Cable is called DAC for short, which is a connect cable for communication equipment, generally used for achieving short-distance interconnect communication, is a very cost-effective high-speed interconnect solution. DAC has only experienced several years that developed from 10G to 40G, so that it can be seen that how fast the development of high-speed data communications. So now, let us talk about the 40G direct attach cable which is still popular today.40G DAC is refers to the copper cable which installed optical modules at the both of end to reach..

Long-distance Connecting Solutions to 40G QSFP+

40G Ethernet comes to be more dominated in the modern network with its high transmission rate. 40G QSFP+ optical module is an important component of 40G Ethernet, which provide high density 40G Ethernet interface for the data centers of the network service providers. Now a verity of 40G QSFP+ optical modules have been appeared on the market, such as 40G Bidi QSFP+ optical modules, 40G QSFP+ for short-distance transmission and 40G QSFP+ for long-distance transmission etc. Here we will describe three kinds of 40G QSFP+ Transceivers for long-distance transmission in detail.QSFP-40G-ER4 QSFP+ Optical ModuleQSFP-40G-ER4 QSFP+ is a hot-pluggable optical module that the data transmission rate up to 44.6Gbps on G.652 single mode fiber and the transmission distance can reach 40km. this optical module has four independent transmission and reception optical signal channels, need to use MUX and DEMUX to multiplex and demultiplex optical signal.QSFP-40G-ER4 QSFP+ optical module are usually used wit..

The Top 10 Topics of 40G transceivers You Should be Reading

40G is gradually taking over the 10G network market as the latter is becoming obsolete due to slow speed and other constraints. So, it is worthwhile to study the 40G transceivers in detail. Cozlink, for you avid learners out there, has investigated and collected the top 10 main topics about 40G transceivers. Here is a brief overview of all 10 of them.Topic 1 - The Definition, Package and Type of 40G transceivers.(1) DefinitionA 40G optical module is a derivative product capable of delivering high density ports and appreciable data transmission speed. It is a high performance, hot-pluggable interconnect solution finding its rampant use in data centers. An integrated model of four independent transmit and receive signals work in consonance to deliver the high density but power-efficient 40G Ethernet connectivity. The 40G applications, apart from in data centers, are also being used widely in high performance computing networks, enterprise core and distribution layers, and telecom operato..
