SFP Definition from JHA

(Small Form-factor Pluggable) A small transceiver that plugs into the SFP port of a network switch and connects to Fibre Channel and Gigabit Ethernet (GbE) optical fiber cables at the other end. Superseding the GBIC transceiver, SFP modules are also called “mini-GBIC” due to their smaller size. By choosing the appropriate SFP module, the same electrical port on the switch can connect to fibers of different types (multimode or singlemode) and different wavelengths. If the fiber is upgraded, the SFP module is replaced.

The SFP converts the serial electrical signals to serial optical signals and vice versa. SFP modules are hot swappable and contain ID and system information for the switch.

Combo SFP Ports

Combo ports are paired with Ethernet ports. For example, if an SFP transceiver is plugged into SFP port 24, then Ethernet port 24 is disabled even if a cable is plugged in.

 

XFP and SFP+ for 10 Gigabits

Larger than SFP, XFP transceivers were the first to handle 10 Gigabit Ethernet optical lines, because SFP supported only up to 4.25 Gbps. The same module size as SFP, SFP+ was later introduced to handle 10 Gbps but required more circuitry in the host device. As a result, SFP+ ports are mostly found in plug-in cards for servers and enterprise switches. See transceiver and GBIC.

The future of telecommunications is happening today in the form of fiber optics. Many ISP and telecommunication providers are rapidly trying to implement, fiber optics into, or in place of, their existing networks.

JHA technology already has this technology in place, and as a result has one of the most advanced networks in the Europe and US.

The greatest advantage of fiber optics is its maintenance free symetrical bandwidth capability and scalability. Fiber optic cables can move an exponentially greater amount of data more efficiently than traditional copper cables.

Fiber optic cables are made of thin strands of glass and transmit data via pulses of light, which are converted into electrical signals. Since light travels faster than electricity, data moves much faster than with other types of cabling.

As fiber optic cables are made of glass and not metal, they do not conduct electricity and therefore do not suffer from signal degrading electrical interference resulting from power sources, electrical appliances or lighting.
