High speed  development of optical communication requires communication system with lower energy consumption and higher bandwidth. SFP  transceiver  plays an extremely important role in this system. This article focus on SFP transceiver. Figure 1: Examples of SFP transceiver. SFP  Transceiver Introduction SFP  module,  also called as small form-factor pluggable or mini GBIC (gigabit interface converter), is a compact, hot-pluggable optical transceiver module. It’s designed to support Fibre Channel, Gigabit Ethernet  and  other communication standards. SFP modules are used in network switches, routers or network interface cards, supporting different speeds such as 2G, 4G or even more. Types of SFP  Transceiver SFP transceiver module comes in various types on the basis of different classification standards. Basically, SFP transceiver is divided into fiber SFP and  copper SFP  types according to the dif...

Cisco is a worldwide leader in the telecommunication industry whose routers, switches are very welcome among the users. To work well with those Cisco networking applications, Cisco SFP transceivers are the best choice. GLC-SX-MM, GLC-SX-MMD, GLC-SX-MM-RGD  and  SFP-GE-S are different types of Cisco 1000BASE SFP transceiver module. All these transceiver modules comply with IEEE 802.3z 1000BASE standard. And since there are similar specifications for these four transceiver modules, users may be confused when they need to choose one SFP module for their Cisco switches. Here we’ll make a comparison of GLC-SX-MM,  GLC-SX-MMD , GLC-SX-MM-RGD and SFP-GE-S transceiver modules to help you choose the suitable one. Which transceiver module will you choose? Cisco Transceiver Datasheet Here are the datasheets of these four different Cisco SFP transceiver modules. GLC-SX-MM Datasheet The GLC-SX-MM is programmed to be fully compatible and functional with all intended Cisco ...

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...
