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...

The Fibre Channel protocol was formulated by the X3T11 team of ANSI in 1988. It has the characteristics of high bandwidth, multi-media, and long-distance transmission. It can realize the transmission of large data files between storage, server and client nodes. In this article, ETU-LINK will focus on introducing the 16G FC DWDM SFP+ series optical modules for 16G Fibre Channel networks. ...

The CDR clock data recovery function plays a vital role in the signal transmission process of the optical module. Today, ETU-LINK will introduce to you what exactly is CDR clock data recovery.   The full name of CDR is clock and data recovery, which can be simply understood as: after the optical signal is converted into an electrical signal, the receiver performs electrical domain shaping and...

Fiber media converters are usually used in pairs to extend the transmission distance of copper cabling systems. But in the process of using, if one side of the link fails, the other side of the media converter will continue to work, and will not send an error report to the administrator. In this case, fiber media converter with FEF function can perfectly solve this problem. Next, we will introduce...

The 10 Gigabit copper module adopts hot pluggable SFP+ package, which can be divided into multi rate and single rate. The multi rate adaptive supports 1G to 10G transmission rate, and the single rate only supports 10G transmission rate. The interface type of 10 Gigabit copper module is RJ45. Its port can support both shielded twisted pair and unshielded twisted pair. It is mainly used in switches,...

We all know that a switch is a network device used to forward electrical (optical) signals, while a router is a hardware device that connects two or more networks. It acts as a gateway between networks and reads the data in each packet. The address then determines how to transmit the dedicated intelligent network device. Next, ETU-LINK will give you a detailed introduction to the differences ...

The OM3 patch cord is a 10-Gigabit multi-mode patch cord. The multi-mode fiber uses light-emitting diodes as the light source, allowing multiple beams of light to propagate in the fiber at the same time, thereby forming a mode dispersion. Mode dispersion technology limits the bandwidth and distance of multimode fiber. Therefore, the core wire of multimode fiber is thick, the transmission speed is ...
