Distinction between SFP multi-mode and single-mode According to the wavelength, it can be divided into 850nm/1310nm/1550nm/1490nm/1530nm/1610nm. The one with wavelength of 850nm is SFP multi-mode with transmission distance of 2KM or less;The one with wavelength of 1310/1550nm is SFP single-mode with

We know that in the present market, Gigabit Ethernet switches generally have two ports: RJ45 port and SFP port, both of which can be transmitted with Gigabit Ethernet. Then what are the differences between the two ports? How should we wire them respectively? This tutorial will answer one by one.Giga

SFP optical module (Small Form-factor Pluggable) can be easily understood as an upgraded version of the GBIC optical module. SFP optical module is half the size of the GBIC optical module, which is only the thumb-size but can configure on the same panel more than double ports on the same panel. The

The optical module integrates precise optical elements and circuit elements. In the daily use, operation by specification should be noticed; otherwise, the optical module is easily broken. Do you know that there is SFP electrical port module in SFP optical module? How to install and remove SFP elect

According to the physical standard, Cisco SFP optical module can be divided into 1000BASE-T, 1000BASE-SX, 1000BASE-LX / LH, 1000BASE-EX, 1000BASE-ZX, 1000BASE-BX10-D / U optical module. The Cisco GLC-LH-SM optical module is a 1000BASE-LX / LH optical module, which will be covered in detail in this a

Most users feel puzzled about the compatibility of SFP and SFP+, and the real point that puzzles them is if the SFP module will work when plugging it into the SFP+ slot. For lots of engineers, this is also an issue that hard to get a clear answer. In this condition, this post will bring you to concl

Fiber optic transceivers are recognized as the most commonly used fiber optic product in fiber optic communication, and they take irreplaceable part in any fiber optic communication or network system. As far as I know, there have been lots of agreements or complaints happened to most of sellers and

Optical fiber communication technology plays an important role in the information transmission, which greatly improves the data transmission speed and becomes the main communication transmission technology in China. Optical module is a very important component in the optical fiber communication tech

Nowadays, as the core optoelectronic device in the optical communication network, the types of the optical module is increasing, and its functions also becoming more and more complicated. Different types of optical modules are emerging such as SFP, SFP +, XFP, QSFP, GBIC and BIDI. We’ll take SFP opt
