Multimode fiber has been developed from OM1 to OM5 now, so which one is better among OM2, OM3, and OM4 multimode fiber? In this blog, ETU-LINK will explain to you.   Multimode fiber is mainly used for optical transmission with a wavelength of 850nm. Here, the two points of effective mode bandwidth and full injection bandwidth can be compared separately. First, let us understand what bandwidth...

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. fiber Channel SCSI ...

Before understanding the differences between single mode and multimode, we need to know that light propagates in a fiber as a set of independent beams, which propagate at a specific angle to the fiber axis and are called modes. We can distinguish between single mode and multimode by transmission mode. Single mode fiber supports one mode, while multimode fiber supports multiple modes. Below, ETU-LI...

Why don’t data centers use multi-mode OM2 fiber anymore? In this article, ETU-Link will reveal the answer for you. Firstly, OM2 is mainly a traditional 50/125 micron graded index multi-mode fiber. OM2 fiber is based on LED light source in terms of standard and design, and has low bandwidth requirements. It cooperates with LED to transmit 1000Mbit/s and lower rates. OM2 will withdraw from the data ...

Now Gigabit Ethernet has been popularized in a large area, and Gigabit Ethernet switches are also widely used in scenarios such as enterprise networks and optical access networks. Gigabit Ethernet has two types of ports, namely RJ45 and SFP ports. These two ports can support the highest transmission rate of Gigabit, and can also be backward compatible with the transmission rate of 10/100M.   ...

In the construction of 5G network, optical module is the basic building unit of 5G network, which accounts for a large proportion of network construction cost and is the key element of 5G low cost and wide coverage. The 5G network bearer network is divided into fronthaul, midhaul, and backhaul. The fronthaul refers to the connection between the active antenna processing unit (AAU) and the distribu...
