The Fibre Channel switch originated from the Fibre Channel protocol. On the fourth layer of the Fibre Channel protocol, the Fibre Channel-based SCSI protocol for storage, the IP protocol for the network, and the virtual interface (VI) protocol for clusters mapped to the network architecture are established. Fibre Channel switches provide Fibre Channel switching for high-bandwidth and low-latency d...

In this article, ETU-Link will explain to you what causes the high temperature of the optical module and how to solve it. Generally speaking, a brand-new optical module will not have any major problems during short-term use.     The optical module is a relatively sensitive optical device. When the operating temperature of the optical module is too high, it will cause problems s...

This blog ETU-LINK takes everyone to understand the difference between optical fiber, copper cable and twisted pair. First of all, let’s understand the twisted pair. The twisted pair is made up of multiple groups of insulated copper wires intertwined. The internal medium of the twisted-pair cable is also copper wire, and the internal transmission is an electrical signal. According to the principle...

一. Introduction to MPO Patch cord The MPO fiber optic patch cord is composed of a hot-swappable MPO connector and a multi-mode/single-mode fiber optic cable. The MPO optical fiber connector includes optical fiber, sheath, coupling components, metal ring, pin, dust cap, etc., and the pin part is divided into two forms: male and female. The male connector has two PIN pins, while the female connector...

The optical module is an important component of the optical fiber communication system, which is used to realize the transmission and reception of optical signals. The speed of the optical module used in the data center ranges from 1G before 2010 to the commonly used 10G and 40G now. Since most of the equipment distance in medium and large data centers is within 500 meters, the interconnection bet...

In this blog, ETU-LINK will focus on introducing the type and transmission distance of the Gigabit single-mode SFP BIDI SC connector optical module. This series of optical modules can not only support 2km, 3km, 10km, 20km, 40km, 60km, 80km, 120km transmission distances, but also have commercial (0℃-70℃) and industrial  (-40℃-85℃) optional temperature ranges. In order to facilit...

In recent years, cloud computing and big data have become an upsurge in our country. In order to provide sufficient bandwidth, many access switches have developed to core switches that can connect to 40G Ethernet. The rapid development of interconnected data transmission is inseparable from the 40G optical module, because it can provide enough bandwidth to ensure that data conversion is unimp...
