Transceiver module is the essential device of a network architecture. As a famous manufacturer of optical products, Cisco published a set of  copper SFP  transceiver modules to support copper networking. Here focus on Cisco SFP compatibility matrix to present a comprehensive Cisco SFP datasheet for you. Overview of Cisco Copper SFP Transceiver Module SFP stands for small form factor pluggable. Copper SFP transceiver is a hot-pluggable transceiver with RJ45 port, so it’s also called SFP RJ45 transceiver. SFP RJ45 transceiver supports 10/100/1000 BASE rate over Cat5 cables. In addition, RJ45 copper transceiver is usually used for transmitting data in a short distance, due to its transmission distance ranging from 10 to 30 meters or from 80 to 100 meters. And  Cisco 1G SFP , copper and RJ45 Ethernet cables are much cheaper than the fiber ones, so it’s wise to choose a copper SFP transceiver to make use of the existing cabling system to optimize your network instead of u...

As information technology develops, we have to upgrade our network products such as the cables, patch panels, etc. Besides, to reduce our data center’s cost, we are tempted to use the old and new ones to make a mixed connection. For instance, run Cat6a cables on  Cat6  patch panel . However, does it work? Is it a reliable connection? Here we’ll discuss it in this article. C omparison of  C at6 and  C at6a  C abling Cat6a and Cat6 are both designed for Gigabit Ethernet. They can handle 10BASE-T, 100BASE-TX, 1000BASE-TX, and 10GBASE-T rate. Cat6 and Cat6a sound almost the same, but a single lowercase “a” sets the two terms apart. The word “a” stands for augmented, which makes them behave differently in performance, size and so on. Cat6 usually has 23 AWG wire  conductors,  and can support  transmission  speed of up to 10Gbps at 250MHz. But the theoretical top distance with 10Gbps speed is only 33-35 meters. ...

IT System administrators are responsible for collecting work details of the servers and infrastructures, so as to provide a reference for subsequent network adjustment and improvement. But it’s a difficult task in large systems with hundreds or thousands of devices. SNMP protocol is born to solve this problem that lets the technicians monitor the network devices such as  data switch , routers and other devices from a single management host. So what is SNMP, and how SNMP works? What  I s SNMP ? SNMP, also written as Simple Network Management Protocol, is an Internet standard protocol implemented on the application layer. The protocol was created in 1898 as a way of monitoring network performance, error rates and so on. The main purpose of SNMP is to define a unified interface and protocol for devices of different categories, versions  and  manufactures. Thus, assisted by SNMP, system administrators can remotely monitor and manage the numbers of systems and device...

Patch panel, an unsung hero, is the most important cable management tool of the data center. When you want to connect a vast number of devices to a central server or other network hardware, there must be plenty of various cables, and you have to plan each thing out properly. It’s always smart to use a patch panel to help you manage the cables and keep your server room organized. However, patch panels are available in different ports and applied in various cables, like 24 port or 48 port patch panel, Cat5e or Cat6 patch panel. There are so many patch panel types on the market that make you confused. Usually, patch panels can be used in two systems, fiber  and  copper cabling systems. Therefore, patch panel types will fall into two main categories, fiber optic patch panel  and   Ethernet patch panel . Fiber  O ptic  P atch  P an el Fiber optic patch panel  is applied in distributing the single mode and multimode fibers to realize the ...

Patch panels act as the central role in the administration of the telecommunication network. They form the primary link for collecting cables and routing data to the place where it needs to be. The most copper cables in network presently use  Cat5e patch panel  or Cat6 patch panel. However, there are various styles of Cat6 patch panels on  market , like punch down or  feed through  patch panels. Consumers may be confused when they need to select one. Here I’d like to talk about Cat6  feed through  patch panel and recommend some for your reference. Why  C hoose  F eed  T hrough   P atch  P anel Compared with punch down type, there is no need to punch down cables with  feed through  panel. Unlike the punch down panel that needs to punch down Ethernet cables for the rear side,  feed through  patch panel have RJ45 ports on both sides, making install cables is fairly simple. Though the price is a bit higher,...
