    What is 1000Base-SX SFP

  • Learning Center    release time:2019-01-15
  • 1000BASE-SX is a fiber optic Gigabit Ethernet standard for operation over multi-mode fiber using. When used with 62.5 micron MMF, its max-working span is around 220 meters, while when used with 50 micron MMF, its max-working span is around 550 meters.

    In practice, with good quality fiber, optics, and terminations, 1000BASE-SX will usually work over significantly longer distances.

    This standard is highly popular for intra-building links in large office buildings, co-location facilities and carrier-neutral Internet exchanges.

    Optical power specifications of SX interface: Minimum output power = −9.5 dBm. Minimum receive sensitivity = −17 dBm.

    Also we will often meet different description about 1000base, like 1000base-LX, 1000base-ZX. 1000base-BX, what is the difference?

    1000BASE-SX • 1000BASE-SX SFP supports link length of up to 550m (depending on fiber type) on multimode fiber at 1Gbps. This optic works at 850nm wave- length and uses an LC connector.

    1000BASE-LX • 1000BASE-LX SFP supports link length of up to 10km on single mode fiber at 1Gbps. This optic works at 1310nm wavelength and uses an LC connector.

    1000BASE-ZX • 1000BASE-ZX SFP supports link length of up to 80km on single mode fiber at 1Gbps. This optic works at 1550nm wavelength and uses an LC connector. 1000BASE BX-D* .

    1000BASE BX-D SFP supports link length of up to 10km point to point on single mode fiber (1490nm TX/1310nm RX wavelength) at 1Gbps bidirectional. This optic uses an LC connector.

    1000BASE-BX optics have two models and must be used in a pair. 1000BX is a technology that allows 1000BASE Ethernet connectivity via single fiber cable.
