Comprehensive analysis of 40G QSFP+ SR4 and 100G QSFP28 SR4 parallel optical modules

图片
  In the process of digitization, data processing, storage and transmission have developed rapidly. The rapid growth of a large number of data search services and video services has led to the development of data centers based on supercomputers and storage. As the main product for short-distance data center interconnection applications, high-speed parallel transmission optical modules have broad market application prospects. In this article, ETU-LINK will introduce the 40G QSFP+ and 100G QSFP28 parallel optical modules applied in data centers. Parallel optical modules are arranged to drive arrays, lasers, detectors, and MCU chips. Signal transmission and reception can be completed through multiple channels, which enables parallel optical communication to support higher rates. Because of this, parallel optical communication needs to use multiple optical fibers to support higher rate transmission, so multi-core connector MPO is needed to support higher data transmis...

200G DAC direct attach cable VS 200G AOC active optical cable

图片
  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...

  Active optical cable AOC is a new type of communication cable. Compared with passive cables or cable-based systems, it has the advantages of high transmission rate, long transmission distance, and low power consumption. It is an ideal solution for data centers, consumer electronics and other fields. Active optical cable AOC has different packages and rates: 10G SFP+ AOC, 25G SFP28 AOC, 40G/56G QSFP+ AOC, 100G QSFP28 AOC , 200G QSFP-DD AOC, etc. In this article, ETU-LINK will introduce you to 56G QSFP+ AOC active optical cable . Before formally introducing the 56G QSFP+ AOC active optical cable, we first understand the QSFP+ AOC active optical cable. QSFP+ AOC active optical cable is composed of optical fiber and two QSFP+ connectors (one at each end). The optical fiber is multi-mode optical fiber, which requires the use of external power supply to convert electrical signals and optical signals. It is mainly divided into 40G QSFP+ AOC active optical cable, 40G QSFP+...

High-speed Cable Product List

  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...
