  • QSFP-DD Might Be the Mainstream Form-factor of 400G Optical Transceivers

    Time to enter 2019, when 400G has become a hot topic in the optical communications industry, the world’s leading optical transceiver manufacturers have launched their own 400G optical modules. When we list the form-factors of these manufacturers’ 400G optical modules (as shown in the figure below), we found that all the manufacturers except the Finisar (acquired by II-VI) have adopted the QSFP-DD form-factor — the market seems to have recognized QSFP-DD as the first choice for form-factors of 400G optical modules, though some manufacturers have also introduced 400G optical modules with OSFP and CFP8 form-factors. 400G Form-factors of Mainstream Optical Transceivers Manufacturers Tips: QSFP-DD is a high-speed pluggable module form-factor defined by the QSFP-DD MSA group. The QSFP-DD MSA group has defined the next generation, high-density, high-speed pluggable module form factor that addresses the industry need for high-density, high-speed networking solutions in a backward compatible form factor. The QSFP-DD Specification has been developed and refined by many companies within the QSFP-DD MSA group and released to the public. Why do mainstream manufacturers choose the QSFP-DD form-factor? Does this mean that the…

  • The Challenges and Opportunities of Silicon Photonics in the Application of Optical Modules

    The Status of Silicon Photonics Technology in the Application of Optical Module With the maturity of waveguide theory and the production of a series of new design devices, the industry has proposed Silicon Photonics technology based on CMOS manufacturing processes. Silicon Photonics utilizes the very mature silicon wafer processing technology of the traditional semiconductor industry. It can process large-scale waveguide devices on the silicon substrate by etching process. By using processes such as epitaxial growth, it is possible to prepare key devices such as modulators and receivers, and finally achieve high integration of modulators, receivers, and passive optical devices. In addition to the laser, the Silicon Photonics technology can realize the integrated manufacturing of various devices in the optical module, covering most components inside the optical module, but does not include the laser chip. Since silicon is an indirect band gap, the conduction band minimum (conducting band bottom) and the full band maximum are in different positions in k space. The electronic transition needs to change the potential energy and kinetic energy at the same time. The laser needs to…

  • High-Speed 100G QSFP28 CWDM4 Optical Transceivers

    Since 2017, the 100G QSFP28 CWDM4 optical transceiver has been the most popular product in the DCI (Data Center Interconnection). This article mainly portrays what the 100G QSFP28 CWDM4 optical transceiver is and why it is so popular. What Is the 100G QSFP28 CWDM4 Optical Transceiver? This Multi-Source Agreement (MSA) defines 4x 25Gbps Coarse Wavelength Division Multiplex (CWDM) optical interfaces for 100Gbit/s optical transceivers for Ethernet applications including 100GbE. Two transceivers communicate over single mode fibers (SMF) of length from 2 meters to at least 2 kilometers, available in SR and LR versions. Why Are the 100G QSFP28 CWDM4 Optical Transceivers So Popular? Longer Transmission Distance The transmission distance of the 100G QSFP28 CWDM4 Optical Transceiver can reach 2km. Although the 100G QSFP28 LR4 optical transceiver can reach 10km, the cost of the 100G QSFP28 CWDM4 Optical Transceiver is much lower, and it can meet a variety of medium and long-distance transmission requirements in the data center. Therefore, 100G CWDM4 MSA Technical Specifications published by MSA is a good complement to the gap due to the high cost of 100G…

  • How to Ensure the Compatibility and Quality of 3rd-party Optical Transceiver?

    When it comes to optical transceiver, as we all know there are 3rd-party optical transceiver and OEM (Original Equipment Manufacturers) optical transceiver. Literally, the 3rd-party optical transceiver is produced by a third-party optical transceiver manufacturer through independent analysis and decoding according to market specifications and standards. Many the 3rd-party optical transceivers are used by many users when they need a large number of optical transceivers to connect their devices. Because the excellent vendors can provide the compatible optical transceivers with a high quality, and the 3rd-party optical transceivers lower price than OEM optical transceivers. However, how do you ensure the compatibility and quality of the 3rd-party optical transceiver? This is a problem that users need to consider when selecting the optical transceivers. This article can give you references to select the 3rd-party optical transceivers. Compatibility References 1. Is there a Data Diagnostic Monitoring Interface (DDMI) as defined by the SFF-8472 specification? DDMI is also called DDM or DOM. DDM can monitor the condition of optical transceiver. Users can remotely monitor — in real-time — received optical power, transmitted optical power,…
