It is known that SDI interfaces can be roughly divided into three types: SD-SDI (270Mbp, SMPTE259M), HD-SDI (1.485Gbps, SMPTE292M) and 3G-SDI (2.97Gbps, SMPTE424M). It is seen from these standards of division that the rate is an important index. For HD-SDI and 3G-SDI, as the commonly-used two types in radio and television industry, maybe there are still many people unfamiliar with…

As the large-scale deployment of 40Gb/s is carried out, many new 100G/s code modulation formats have emerged in the industry. For various transmission code patterns with different features, based on the comprehensive consideration on parameters of other system design, comprehensive selections are made from perspectives of transmission distance, channel spacing, compatibility with 40Gb/s and 10Gb/s systems, costs of optical transceiver…

Since the end of last year, the heat of the word “5G” has remained high. As a cutting-edge communications technology, 5G has many terms. Due to the oversimplification and nastyness of the names of standards, specifications, and technologies adopted by various institutions and the complexity of 5G technology itself, there are many similar and confusing phenomena in these terms. This…

Video optical transceivers are primitively used in radio and television industry. It mainly includes two series: video SFP module or video SFP+ transceiver. Then today’s topic will be involved in types and applications of SDI video SFP optical transceiver in this post. The Definition of SDI Video SFP SDI SFP optical module and its related products are initially designed for…

With the increasing of enterprise informatization application system, the space, electricity distribution system and air conditioning refrigeration of data centers tend to be saturated. Simultaneously, the utilization rate of the servers is generally low. In order to solve the contradiction between the development of data center and the rapid growth of information resources, the concept of cloud computing and the…

SDI optical transceivers are known to many people, initially applied in the radio and television industry. SDI series optical modules include many types, such as SDI SFP optics(mainly includes 3G-SDI Video SFP, 6G-SDI Video SFP, 12G-SDI Video SFP), SDI SFP+ optical module(mainly includes 3G-SDI Video SFP+, 6G-SDI Video SFP+, 12G-SDI Video SFP+), etc. Then today we will talk about types…

Both 4WDM and CWDM4 belong to 100G QSFP28 series optical transceiver, and are certainly related to WDM (wavelength division multiplexing)tech. Maybe there are still people confused of what differences between QSFP28 4WDM and QSFP28 CWDM4 optical transceiver are. Then in this article, a comparison between them will be made by Gigalight. An Introduction to 100G QSFP28 4WDM Optical Transceiver 4WDM(4-Wavelength…

To satisfy the increasing demands on more-cost-effective and lower-power-consumption 100G optical networks, 100G QSFP28 4WDM optical transceivers emerge in the market. 100G 4WDM series optical module currently includes three specifications in total: 100G QSFP28 4WDM-10, 100G QSFP28 4WDM-20, 100G QSFP28 4WDM-40. Today, in this article, Gigalight will mainly introduce them for you. Before coming into today’s topic, it will be…
