Intro to Cisco Gigabit Ethernet SFP Transceiver Modules
SFP (Small Form-Factor Pluggable) transceiver is a hot swappable I/O device that plugs into a Gigabit Ethernet port or slot, linking the port with the network. Gigabit Ethernet SFP transceivers are designed to use with Gigabit networks. They are compliant to IEEE 802.3 standards and with different

The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the SFF Committee. It is a popular
Read article →Technical articleDo I choose a branded or compatible SFP?
A SFP (small form-factor pluggable) is a small transceiver that plugs into the SFP port of a network switch and connects to Fibre Channel and Gigabit Ethernet (GbE) optical fibre cables at the other end. By choosing the appropriate SFP module, the same electrical port on the switch can connect to
