As an important part of the optical network transmission, the optical fiber module functions as a photoelectric conversion, so that the signal can be transmitted in the optical fiber. So, do you know how to distinguish whether an optical fiber module is single-mode or multi-mode? Next, ETU-LINK will teach you a few ways to distinguish between multi-mode fiber modules and single-mode fiber modules....
In this article, ETU-LINK will introduce the application of optical modules in the data center computer room. As we all know, the construction of the data center computer room is a system project. It consists of the following parts: the host room (including network switches, server group, storage, data input, output wiring, communication area and network monitoring terminal, etc.), basic work...
With the gradual improvement of living standards, the concept of networked and intelligent buildings is no longer unfamiliar to everyone. In intelligent buildings, we can not only exchange data information quickly, control lights and adjust air conditioning through the network system, but also build intelligent scenes such as network monitoring systems and intelligent parking systems. In order to ...
DWDM is a dense wavelength division technology. This technology multiplexes the tight spectral spacing of a single optical fiber carrier in a designated optical fiber in order to utilize the achievable transmission performance. This technical solution is used to increase the bandwidth of the existing laser technology on the optical fiber backbone network. The following ETU-LINK will introduce 10G ...
Nowadays, the rapid development of data services has led to an increasing speed of IP network convergence, so network expansion is very important. In the construction of metropolitan area networks, there is a widespread problem of optical fiber shortage. Because metro expansion requires less channel numbers than trunk systems, and the distance is relatively short, optical amplification is not requ...
As one of the cores of medium and long-distance optical communication, the optical module plays a role in photoelectric conversion. It is composed of optical devices, functional circuit boards, and optical interfaces. Today, ETU-LINK will introduce to you the components of the optical module—TOSA and ROSA. 1、TOSA TOSA is the main component of the optical transmitter module, whose main functio...
Optical modules can be classified into single-fiber and dual-fiber according to the number of interfaces. Dual-fiber optical modules have two optical fiber interfaces, and single-fiber optical modules have only one optical fiber interface. In addition to the difference in optical fiber interfaces, the use of the two is also different. Therefore, ETU-LINK will introduce the precautions for the use ...
In this article, ETU-LINK will introduce to you, what is the difference between active optical cable(AOC) and direct attach cable(DAC)? First, the AOC is composed of integrated optoelectronic devices. The signal transmission process is that the A terminal module converts the electrical signal into an optical signal, the optical signal is transmitted to the B terminal module by an optical fiber pat...
The previous storage technology only uses the storage device as an auxiliary device of the server. The large-capacity data exchange between servers can only rely on traditional networks, and cannot adapt to the development of IT technology in terms of speed, security, cross-platform sharing, and unlimited expansion. Under such circumstances, SAN technology came into being. Fibre Channel SCSI techn...
As an important part of the optical fiber communication system, the optical module plays the role of photoelectric conversion. In this article, ETU-LINK will introduce to you what are the core components of the optical module? 1. TOSA: Its main function is to convert electrical signals to optical signals, including lasers, MPD, TEC, isolator, Mux, coupling lenses and other devices, including ...
32G Fibre Channel network is the sixth-generation channel technology. In the next 10 years, Fibre Channel will still be the preferred storage protocol for data centers. In this article, ETU-LINK will introduce the 32G SFP28 FC multi-mode(MM) optical module and its application in the data center 32G storage network SAN. 32G SFP28 FC MM optical module (ES2853X-3LCD01) adopts hot-swappable SFP28...
In the establishment of a 10G network, we will face a choice, that is, whether we choose optical fiber cabling or copper cabling. Optical fiber cabling systems are divided into multi-mode(MM) optical fiber cabling systems and single-mode(SM) optical fiber cabling systems, among which 10G MM optical fiber cabling systems need to use 10G SFP+ MM optical modules, 10G AOC active optical...
