What is 100FX SFP?

The Cisco 100BASE-FX Small Form-Factor Pluggable (SFP) Fast Ethernet Interface Converter (GLC-GE-100FX=) is a hot-swappable device that plugs into a Gigabit Ethernet SFP port on Cisco Catalyst 3750 Series, 3560 Series, and 2970 Series switches.

What is 100FX fiber?

100BASE-FX is the technical name of Fast Ethernet over fiber optic cables. It is a version of Fast Ethernet carrying data traffic at 100 Mbps (Mega bits per second) in local area networks (LAN). It was launched as the IEEE 802.3u standard in 1995.

Is Fast Ethernet full duplex?

Full-duplex 10 Mbps Ethernet has simultaneous 10 Mbps receiving and 10 Mbps sending paths. Fast Ethernet standard (IEEE 802.3U) increases Ethernet by operating speeds from 10 Mbps to 100, half or full duplex.

When was Gigabit Ethernet introduced?

1998
In 1998, three years after the introduction of Fast Ethernet, Gigabit Ethernet was introduced by IEEE to replace Fast Ethernet. It provided a data rate of 1 Gb and initially required the use of fiber optic cables. In 1999, a new standard was passed that enabled UTP Cat5, Cat5e or Cat6 cabling to be used.

What is the distance limitation of 100baset?

The segment length for a 100BASE-T cable is limited to 100 metres (328 ft) (the same limit as 10BASE-T and gigabit Ethernet). All are or were standards under IEEE 802.3 (approved 1995). Almost all 100BASE-T installations are 100BASE-TX.

How long can SFP cables be?

“Do not use a fiber optic cable that is longer than 100 meters. The cables for small-form factor pluggable (SFP+) modules can be longer than 100 meters. See the product documentation for detailed information on SFP+ modules.”

How many wires do I need for a full-duplex?

4 wires
Full Duplex means that data can pass simultaneously both to and from the instruments. This requires 4 wires – one pair to Transmit and one pair to Receive.

How far can fiber be run?

Modern fiber optic cables can carry a signal quite a distance — perhaps 60 miles (100 km). On a long distance line, there is an equipment hut every 40 to 60 miles.
