By What is SFP GE L?
SFP-GE-L is a Cisco 1000Base SFP Optical Transceiver. This SFP transceiver supports links up to 10km long over 9/125µm singlemode fiber. Like all of our transceivers, the SFP-GE-L is preloaded with all the necessary configuration data for unparalleled network performance and integration.
What is the difference between LX and SX SFP?
1000BASE-LX single-mode SFP module will work with single-mode fiber in order to perform both transmission and reception of data. Whereas 1000BASE-SX multimode SFP transceiver will work with multimode fiber, which has a thicker core and allows higher speed at shorter distance.
Are SFP hot-swappable?
Small form-factor pluggable, or SFP, devices are hot-swappable interfaces used primarily in network and storage switches. The SFP ports on a switch and SFP modules enable the switch to connect to fiber and Ethernet cables of different types and speeds.
How do I choose a SFP module Cisco?
When choosing SFP modules, you should consider whether it matches the switch port and the cable you have prepared. If you have multimode cable, then you can choose GLC-SX-MM 1000BASE SFP. If you use single-mode fiber cable, you should select GLC-LH-SM 1000BASE SFP.
What does SFP stand for?
small form-factor pluggable
SFP stands for “small form-factor pluggable.” SFP transceivers are compact and hot-pluggable devices that act as an interface between networking equipment (switch, router, network card) and interconnecting cabling (copper or fiber).
What does an SFP do?
The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for data communication applications. These small metal devices plug into a special switch slot and support communication over either fiber optic or copper networking cable.
What does LX mean in SFP?
long wavelength
The “LX” in 1000BASE-LX stands for long wavelength, indicating that this version of Gigabit Ethernet is intended for use with long-wavelength transmissions (1270–1355 nm) over long cable runs of fiber optic cabling.
What are the types of SFP?
SFPs are mainly classified based on their speed capabilities. Some of the types are 100Base, 1000Base Gigabit, and 10Gig (SFP+). For most Fiber SFP modules, the transmission speed is 1 Gigabit, but the newer versions such as SPF+ have a higher speed of transmission, from 10 to 25 Gigabit.
How do I know if SFP is multimode?
Multi-mode SFP Color Coding As with Singlemode SFPs, Multi-Mode SFPs are identified by the color of the Bale Clasp: Black color coded bale clasp designates a Multi-mode SFP. The color of the compatible fiber optic patch cord or pigtail is orange.
Is SFP faster than Ethernet?
Since RJ45 Ethernet port and SFP port actually run at the same speed, choosing RJ45 ports to connect switches might be more economical as Cat5e/Cat6 cable is lower-priced than the SFP connection with both transceivers and corresponding cables.

Can a GLC-GE-Dr-LX SFP interoperate with other 100m SFPs?
The GLC-GE-DR-LX SFP can interoperate with other 100M SFPs/interfaces as long as those are based on 100BASE-LX10 standard. A 5dB attenuator is needed on the path of dual-rate SFP Tx and 100BASE-LX10 interface Rx. No attenuator is needed on the other fiber strand.
How are Cisco SFP modules for Gigabit Ethernet applications?
Cisco SFP Modules for Gigabit Ethernet Applications Data Sheet 1 Hot swappable to maximize uptime and simplify serviceability 2 Flexibility of media and interface choice on a port-by-port basis, so you can “pay as you populate” 3 Robust design for enhanced reliability 4 Supports Digital Optical Monitoring (DOM) capability
