In the optical communications field, many devices have similar functions, such as optical transceivers and media converter, they are the equipment for photoelectric conversion. Do you know their differences?Let’s learn about this. What is media converter? Optical media converter is a medium for converting short distance electrical signals and long distance optical signals. It is also called photoe...
When install a Optical fiber optic network, people may make some common mistakes, which were usually overlooked. In this blog, we will list the most common ones. Hope to give you some guidance for your optical network installation. 1.SFP BIDI transceiver must be used in pair The SFP BiDi transceiver must be matched correctly. Take an example: The paired BIDI transceivers connect with switch A and ...
Today we want to share some about the media converter with you after some customers asked about it. Media converter is made up for the traditional Ethernet short transmission distance to realize long distance transmission of the signal. Media converter is a transparent bidirectional converter to provide the data signal to Ethernet&nb...
Optical fiber splitters play an increasingly important role in today's optical networks. From the FTTx system to the traditional optical network, it can not only enable many users to share an optical fiber interface, but also can help users extend the function of optical network circuits. Today we'll give you a brief introduction to fiber splitter. With the continuous development of modern technol...
Since the physical fiber optic cabling is expensive for each individual service, it is highly advisable to use a WDM technology for expanding the capacity of the fiber to carry multiple client interfaces. DWM have two types, includes CWDM & DWDM. Today we talk about the knowledge of 10G CWDM 80KM. About 10G CWDM 80KM ETU-Link's ESPCxx92-3LCD80: 10G SFP+ CWDM 80KM Transceiver is a "Limitting mo...
Since 1970, the wire and cable industry has used low-smoke, low-halogen materials in many areas. As the improvements of environmental awareness and safety issues, made people realize that wires and cable jackets play a very important role in fires, And have led to the widespread adoption of low-smoke, Zero halogen (LSZH) optical cable. But what is the LSZH? Today we had a training about ...
With the continuous development of big data and cloud computing, the demand for high bandwidth and high-speed network has increased greatly. However, solving this problem often costs a great deal, the emergence of MTP/MPO patch cords is a good solution to this problem. Following we will analyze the MTP/MPO patch cord for everyone. What is MTP/MPO patch cord? The MTP/MPO patch cord consis...
