As a switch brand equipment manufacturer, HP's equipment supports a variety of optical modules with different specifications. Users can choose the appropriate optical module according to their needs. Common optical modules are 100G QSFP28, 40G QSFP+, 25G SFP28, 10G SFP+ and 1.25G SFP etc. Below, ETU-LINK will give you a list of some commonly used HP optical module models. HP 1.25G SFP dual fiber s...
Two important development trends of optical modules are to increase the transmission rate and extend the transmission distance. However, as the transmission rate increases, the signal transmission distance will be limited by many factors, such as chromatic dispersion, nonlinear effects, and polarization mode dispersion. These factors will limit the increase in transmission rate and trans...
With the mature development of 100G technology and the advent of 100G products, the deployment of large enterprise network and data center is evolving towards 100G. At present, 100G optical modules on the market include CFP, CFP2, CFP4, QSFP28 and CPAK. The sizes of 100G optical modules in different packages are different. Among them, the 100G optical module in QSFP28 package has the smallest...
The QSFP28 package has become a mainstream 100G optical module with smaller size, power consumption and price advantages. In practical applications, how should we solve the interconnection requirements of 100G ports and 40G, 25G, and 10G ports? Below, ETU-LINK will introduce several common solutions to you. QSFP28 port interconnects with QSFP+ port We need to change the switch port configur...
With the increasing network bandwidth, many data centers have upgraded their 10G network to 40G. There are many solutions for 40G optical modules, such as 40G SR4 and 40G LR4. Today, etu-link introduces an optical module suitable for upgrading 40G network on the basis of 10G network wiring. It is 40G QSFP+ LX4 optical module. Different from other 40G QSFP+ optical modules, it can use either multim...
In 40G short-distance optical network transmission, the conventional optical module solution is to use QSFP-40G-SR4 optical module and 12-core MPO multi-mode OM3 fiber patch cord. Although this solution can realize the upgrade of 10G network to 40G network, it uses MPO branch jumpers to connect 10G equipment and 40G equipment are obviously too expensive, so the industry has given a new optica...
Fiber optic communication has completely replaced cable communication due to its advantages of high transmission quality, small size and weight. As an important part of fiber optic communication, optical module mainly plays the role of optical signal conversion, converting electrical signals of network equipment into optical signals, so that data can be transmitted in fiber. The following ETU-Link...
In this article, ETU-Link will introduce the connection between the server and the switch and the construction scheme of the campus network. Speaking of the server, in fact, it is a little similar to the computer we use in daily life, which is the equipment to provide computing services. The composition of the server includes processor, hard disk, memory, system bus, etc. As the server needs to re...
