1000Base-SX Gigabit Ethernet Media Standard

1000Base-SX is an Ethernet Media Standard, for transmitting data over multi-mode fiber optic cables, instead of copper twisted pair cables. 1000Base-SX uses multi-mode fiber (MMF) optic cable instead of copper twisted pair cable. Gigabit Ethernet can transmit data at the rate of one gigabit per second (1,000,000,000 bits per second). Gigabit Ethernet is replacing FastEthernet as the LAN networking standard all over the world.

1000Base-SX standard can transfer data to a distance between 220 meters and 550 meters.

1000Base-SX Ethernet standard uses multimode fiber (MMF) optic cable with 62.5 micron core, with 850 nanometer light wavelength can transmit up to 220 meters length. 1000Base-SX based Gigabit Ethernet devices use LC type of connectors. Image of a cable and its connectors are shown below.

Main characteristics of 1000Base-SX based Gigabit Ethernet are listed below.

• Operating speed of 1000Base-SX Gigabit Ethernet is 1 Gbps (1,000,000,000 bits per second).
• Gigabit Ethernet supports distances between 220 to 550 meters.
• Multi-mode fiber is used as shown in above picture.

100 Mbps FastEthernet network devices had replaced by 1000Base-T Gigabit Ethernet with a speed of 1,000,000,000 bits per second.

Feed your brain that Gbps is used to represent Gigabits per second.
