Cisco® MFE and MGE Small Form-Factor Pluggable (SFP) or mini Gigabit Interface Converter (mini-GBIC) transceivers are easy-to-install modules that provide a simple way to add fiber connectivity or to add an extra Gigabit Ethernet port to your Cisco Small Business or Cisco Small Business Pro Series switches. The transceivers are available for single-mode or multimode fiber-optic cabling and can support distances from 100 meters up to 40 kilometers.
The Cisco MFE and MGE transceivers provide fast and reliable connectivity between switches that are located on different floors, in separate buildings, or on a small campus network needing connectivity between sites. These transceivers can support both Fast and Gigabit Ethernet applications.
This easy-to-install MGBSX1 Mini-GBIC (or SFP) module provides a simple way to add Gigabit functionality to your Linksys switch. Gigabit fiber is often used to connect two switches together. The technology used depends on the distance between the two switches. The SX module uses 850 nanometer wavelength light in multimode fiber optic cables, and can achieve distances up to 220 or 550 meters, depending on the fiber used.
