QSFP-DD Wiki QSFP-DD is a Double-Density QSFP. It is similar to current QSFP but a new module with an additional row of contacts providing eight lane electrical interface. QSFP-DD MSA QSFP-DD is being developed by QSFP-DD MSA. QSFP-DD MSA defined all physical features such as electrical specifications, mechanical dimensions, cage and receptacle. The advantages of…

SFP-10G-SR vs SFP-10G-SR-S, What is the difference? SFP-10G-SR is a standard 10G SFP+ SR transceiver. It supports 10GBASE-SR up to 300m link lengths on OM3 MMF or 500m on OM4 MMF. SFP-10G-SR-S is a 10G SFP+ SR transceiver but can’t support FCoE applications. SFP-10G-SR vs SFP-10G-SR-X, What is the difference? SFP-10G-SR-X is a multi-rate 10G…

What is an SFP? SFP is a packaging form of optical modules, and its full name is small hot-swappable optical transceiver integrated module. The SFP optical module is currently the smallest pluggable optical module, and each 1U panel can support up to 48 SFP ports. The SFP optical module contains one channel of transmission and…

With the advancement of science and technology and the needs of market development, coherent light technology has developed from being difficult, high-cost, and high-power consumption in the early 1990s to becoming a hot topic in the field of optical communications. If you want to learn more about the development and technical characteristics of coherent light,…

Optical modules can be divided into single-mode optical modules and multi-mode optical modules according to fiber type. Different fiber types have different characteristics such as fiber core and transmission distance. This article will analyze in detail the different properties of single-mode and multi-mode optical fibers, and how to achieve conversion between single-mode and multi-mode optical…

Recently, in our communication with customers, we found that customers are often confused about the choice between single-mode and multi-mode SFP, so we feel it is necessary to write an article to analyze their characteristics in detail, hoping to help everyone.   What is Single-mode SFP? The single-mode SFP module uses a single-mode laser inside,…

WDM and CWDM and DWDM explained What is a wavelength? Light is a kind of electromagnetic wave, and the wavelength refers to the distance between the peak/trough of the electromagnetic wave and the adjacent peak/trough. What is WDM? WDM is the abbreviation of Wavelength Division Multiplexing. It refers to a technology that couples optical carrier…
