Some of you would ask about the interfaces on the Switch. It is the transmission medium conversion on the pure physical layer, which is actually the conversion of optical signals and electrical signals.<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Some of you would ask about the interfaces on the Switch. How to use it? Let’s learn more about it now.<\/p>

What is a Fiber Connector?<\/strong><\/p>

The optical fiber interface is the physical interface used to connect optical fiber cables. The principle is that the light enters the light-sparse medium from the light-dense medium, resulting in total reflection. Usually, there are several types such as SC, ST, FC, etc., which are used as an optical fiber bandwidth interface for large equipment such as computer rooms and cabinets.<\/p>

The main module types of optical fiber are as follows:\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

When it comes to optical ports, we can\u2019t help but mention GBIC and SFP. What is SFP? Is the SFP optical module.<\/p>

GBIC is an interface device that converts gigabit electrical signals into optical signals. GBIC can be hot-swapped in design. GBIC is an interchangeable product that conforms to international standards. Gigabit switches designed with GBIC interface have a large market share in the market because of their flexible interchange. SFP can be simply understood as an upgraded version of GBIC.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

SFP supports SONET, Gigabit Ethernet, Fibre Channel and some other communication standards. This standard is extended to SFP+ and can support a 10.0 Gbit\/s transmission rate, including an 8-gigabit Fibre Channel and 10GbE. Compared with Xenpak, X2 or XFP versions of modules, SFP+ modules leave some circuits on the motherboard instead of being implemented in modules.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

SFP+<\/strong><\/p>

SFP+ is an optical fiber module, an optical transceiver that is hot-swappable and independent of communication protocol, and an upgrade of SFP. SFP has been widely used in Ethernet and 1G, 2G and 4G fiber channels. In order to adapt to the higher data rate, SFP+ has designed electromagnetic shielding and signal protection features that are stronger than SFP, and formulated a new electrical interface specification.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

What is an Ethernet port?<\/strong><\/p>

The Ethernet port is relative to the optical port, which refers to the physical characteristics of the fire extinguisher, mainly refers to the copper cable, and is the processed electrical signal. At present, the commonly used network interfaces include 100-megabit port and gigabit port.<\/p>

Simply put, the\u00a0Ethernet port\u00a0is an ordinary network cable interface, with a general speed of 10M or 100M, and some of them support 1000M. The longest distance of the\u00a0Ethernet port is\u00a0100m.<\/p>

The difference between an optical port and an Ethernet port<\/strong><\/p>

1. It is the transmission medium conversion on the pure physical layer, which is actually the conversion of optical signals and electrical signals.<\/p>

2. The optical port is what we usually call an optical board expansion slot that can be inserted into an optical fiber for long-distance data transmission; the Ethernet port is what we often call RJ45 port, that is, the network cable port.<\/p>

3. All below 155Mb\/s are electrical interfaces, and all above 155Mb\/s are optical interfaces; 15 MB\/s can be an electrical interface or an optical interface; The local connection can be an electrical interface or an optical interface; Inter-office connections are all-optical transmission; Connect with coaxial cable for electrical signals.<\/p>

Finally,\u00a0<\/strong><\/p>

1. In contrast, optical fiber will be much more complicated. The interface types of optical fiber interfaces in different rates are different, such as SFP (Gigabit Optical Interface) and SFP+ (10 Gigabit Optical Interface) introduced earlier, and QSFP+(40G Optical Interface) will also be encountered in the project.<\/p>

2. To use the switch\u2019s 10-Gigabit optical port, you need to plug in SFP+ 10-Gigabit optical module. The 10-Gigabit dual-core optical module (dual-core is the most commonly used, one receiving and one sending) will have two LC interfaces.<\/p>

3. If two switches are connected, the LC-LC fiber jumper is required. If the switches are connected to the distribution frame, it depends on the type of distribution frame. If the opposite end is FC distribution frame, the jumper required is LC-FC jumper.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
