A high-quality optical module can ensure the flexible operation of high-density optical network, and provide convenience for subsequent management and expansion. So how should we judge the quality of optical module? Next, ETU-LINK will give you some judgment indicators. The optical module shall comply with MSA multi-source protocol, and the manufacturer shall pass CE, ROHS, FCC ...
In the optical network solution, the unit cost of optical module as an accessory of switch is not as high as that of switch, but if the switch ports are full of optical modules, especially the original optical modules provided by equipment suppliers such as Cisco and Huawei, the total cost will be very high. Therefore, in order to reduce the total cost, many users will choose the third-party ...
Armored patch cord is a new type of optical fiber patch cord designed with a layer of stainless steel sleeve to protect the optical fiber. It has the advantages and functions of standard optical fiber patch cord, but at the same time has the durability of armor. The following ETU-LINK will give you a detailed introduction to the advantages, types and uses of under-armored fiber optic patch co...

At present, the 2.5G optical modules supplied by ETU-LINK are divided into three types: single fibe...
2020 is the first year that 5G will be commercialized. At present, 25G optical modules have also been used in the construction of 5G signal base stations. Among them, 25G CWDM optical modules have a high market prospect in 5G fronthaul. Compared with other 25G optical modules, 25G CWDM optical module can save more fiber resources, thus effectively saving the total cost of operators. As early as 20...
There are four types of 10G CWDM optical modules: 10G SFP+ CWDM, 10G XFP CWDM, 10G SFP+ DWDM, and 10G XFP DWDM. Among them, the CWDM series of optical modules have an optional band of 1270-1610nm with an interval of 20nm, and the DWDM series of optical modules are optional. It is C17-C61. Next, ETU-LINK will introduce to you what 10G CWDM optical modules are available. 1、10G SFP+ CWDM se...
EPON is a passive optical network based on Ethernet, which is an important part of optical access technology. The PON network consists of OLT (optical line terminal), ODN (passive optical splitter network) and ONU (optical network terminal). Partial composition. OLT equipment is located at the core position in the network topology. It accesses multiple service networks upwards, and accesses multip...
In the optical fiber communication network, the optical transceiver module which realizes the photoelectric conversion function occupies a very important position. The high-speed optical module has become the focus of the major operators, but the 10G Optical module still has its value. Next, ETU-LINK will introduce the 10G CWDM XFP optical module. 10G CWDM XFP optical module adopts hot swap XFP pa...
With people’s urgent demand for information resource sharing and information exchange, prompting the rapid development of network technology, universities are also preparing to build campus networks, hoping to improve teaching, management, and scientific research through the construction of campus networks. Campus network applications can be divided into three parts: e-learning (multimedia classro...
Metropolitan area network is a computer communication network established within a city, referred to as MAN. It is a broadband local area network. Due to the local area network technology with active switching elements, the transmission delay in the network is small, and its transmission medium mainly uses optical cables, and the transmission rate is above 100Gbit/s. An important use of MAN is for...
