Cisco SFP Overview

As is known to all, Cisco is one of the most famous brands in the world, leading the telecommunication industry. Cisco SFP is the small form factor pluggable with Cisco brand, which is widely used in many telecommunication and data communications applications. Today we are going to talk about Cisco SFP so that you can have a better choice for building your network.

First and foremost, before you get to know about Cisco SFP, the first thing you should have a good knowledge about is its features, which illustrates why Cisco SFP is so popular.

• Interchangeable SFP for fiber type, distance and connector
• IEEE 802.3 compliant
• Conforms to small form-factor pluggable Multi-Source Agreement (MSA)
• Operating temperature: -40˚ C to +75˚ C
• Storage temperature: -40˚ C to +85˚ C
• No in-field adjustments required

Except the features of good quality and reliability, Cisco SFP can also save your money. Some people may say that saving money on SFP modules does not amount to a huge sum of money. So, in order to make it reliable, please take a look at a real-life example from one of our customers and see how it plays out. Below represents purchases of Cisco compatible SFP module GLC-SX-MM.

Applications

Generally, Cisco's SFP modules can be designed to use for three main applications. They are Fast Ethernet SFP, Cisco Gigabit Ethernet SFP and CWDM SFP. Next, each application will be given a brief description.

Cisco Fast Ethernet SFP - Cisco Fast Ethernet SFP comes in six configurations which can be described as the Cisco 100BASE-X SFP. It is a hot-swappable input/output device that plugs into Fast Ethernet ports, dual-rate Fast/Gigabit Ethernet ports, or Gigabit Ethernet ports of a Cisco switch or router, linking the port with the fiber cabling network. One of its configuration is 100BASE-FX SFP whose part number is GLC-FE-100FX or GLC-GE-100FX, operating on ordinary multimode fiber optic (MMF) link spans up to 2 kilometers long. But there is a point you should note that GLC-FE-100FX is for 100Mbps Ethernet ports, while GLC-GE-100FX is for Gigabit Ethernet ports.

Cisco Gigabit Ethernet SFP - Cisco SFP for Gigabit Ethernet can be described as Cisco 1000BASE-X SFP, which plugs into a Gigabit Ethernet port or slot. Compared with Cisco Fast Ethernet SFP, its speed and capacity are better. And currently, it still plays an important part in the telecommunication networks. For example, 1000BASE-SX SFP, which is a cost effective module with high performance, can support dual data-rate of 1.25Gbps/1.0625Gbps and 550m transmission distance with MMF.

Cisco WDM SFP - The speed of Cisco WDM (Wavelength-Division Multiplexing) SFP can be up to 10Gbps, so it is also called Cisco 10GBASE-X SFP. It has two types of CWDM (Coarse Wavelength-Division Multiplexing) SFP and DWDM (Dense Wavelength-Division Multiplexing) SFP in that WDM can be divided into CWDM and DWDM. They both allow enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel services in their networks.

With the technology advanced, there is a growing number of SFP modules compatible to Cisco brand. Fiberstore offers various Cisco SFPs, including the above three applications. Click Fiberstore and you can search what kinds you want, so that you have a better choice for you network building.
