  200G Ethernet has become a hot topic in the market due to its trend of higher transmission rate, higher density, and lower device power consumption. As important components, 200G optical modules , 200G DAC, and 200G AOC have also received attention from everyone. In this blog, ETU-LINK will talk about 200G DAC direct attach cables and 200G AOC active optical cables. 200G DAC The 200G DAC direct attach cable mainly comes in two packages: QSFP56 and QSFP28-DD. The difference between the two is that the QSFP56 DAC package uses four transmit and receive ports, each with a transmission rate of 50G, while the QSFP28-DD DAC package has eight transmit and receive ports, each with a transmission rate of 25G, and is compatible with QSFP forward and backward, and can be compatible with existing QSFP28 optical modules and AOC/DAC high-speed cables. 200G QSFP56 direct attach cables are divided into three types: 200G QSFP56 to QSFP56 DAC, 200G QSFP56 to 2x100G QSFP28 DAC, a...

  As a cost-effective high-speed data communication solution that replaces optical modules, high-speed cables are widely used in storage area networks, data centers, and high-performance computer connections. In this blog, ETU-LINK will introduc e high-speed cables. High-speed cable ( Direct Attach Cable , referred to as DAC) is a kind of cable assembly purchased in a fixed length with fixed connectors at both ends, used for interconnection between short-distance devices. The connectors used for the high-speed cable are the same as optical modules. However, compared with optical modules, the connector modules of high-speed cables do not have expensive optical lasers and other electronic components, thus greatly saving costs and power consumption in short-distance applications. Generally, if the transmission distance is less than 7M, it is recommended to use high-speed cables, which are more cost-effective. Otherwise, AOC active optical cables or optical modules...

  The Alcatel-Lucent OmniSwitch 6860 Virtual Chassis Full Layer 3 Ethernet Switch is a compact, high-density Gigabit Ethernet (GigE) and 10 Gigabit Ethernet platform designed for converged networks. There are four models of this series: OS6860-P24, OS6860E-48, OS6860E-P24Z8, and OS6860E-U28. The following ETU-LINK will introduce the OS6860E-48 switch and optical module solutions separatel y . The OS6860-48 switch is equipped with 48 10/100/1000 Base-T ports and 4 1G/10G SFP+ ports. The configurable optical modules are shown in the table below. If the transmission distance between devices is short, you can also use 10G SFP+ direct attach cables . The above is ETU-Link's recommended Alcatel-Lucent OS6860E-48 switch optical module matching solution. For more optical module matching solutions, please refer to previous blog s.
