Frequently Asked Questions

Juniper 1000BASE SX SFP Mini Gigabit Transceiver (EX-SFP-1GE-SX)
Frequently Asked Questions (FAQ's)



What is Juniper 1000BASE-SX?
  • It is a gigabit Ethernet standard that transmits data at 1 Gbps via multimode fiber (MMF) using a short-wavelength laser (850 nm).
    • What type of fiber does 1000BASE-SX use?
  • Multimode fiber (MMF).
    • What is the maximum distance 1000BASE-SX can support?
  • Depending on the fiber kind and quality, up to 550 meters.
    • Which connector type is used with 1000BASE-SX modules?
  • Typically LC connectors.
    • Can 1000BASE-SX be used with single-mode fiber?
  • No, it is designed specifically for multimode fiber.
    • What is the wavelength used by 1000BASE-SX?
  • 850 nanometers.
    • Is Juniper 1000BASE-SX hot-swappable?
  • Yes, it can be inserted and removed without powering down the device.
    • Does 1000BASE-SX support full-duplex operation?
  • Yes, it supports full-duplex communication.
    • Can a Juniper 1000BASE-SX transceiver work in a Cisco switch?
  • Not natively; vendor lock determines compatibility, and a third-party or programmed transceiver can be needed.
    • What devices are compatible with 1000BASE-SX?
  • Juniper switches and routers with Gigabit Ethernet and SFP slot support.
    • Is digital optical monitoring (DOM) supported?
  • Some Juniper SFP modules support DOM; check the specific model.
    • What is the typical power consumption of a 1000BASE-SX transceiver?
  • Around 0.8 to 1.0 watts.
    • Are there environmental limitations for 1000BASE-SX transceivers?
  • Indeed, unless they are industrial-grade, they usually function in temperatures between 0°C and 70°C.
    • What is the data rate of 1000BASE-SX?
  • 1.25 Gbps line rate (1 Gbps payload).
    • Can I use a 1000BASE-SX module for long-range communication?
  • No, it is designed for short-range over MMF; for extended distances, use long-range optics like the 1000BASE-LX.
    • Can third-party 1000BASE-SX modules be used in Juniper devices?
  • However, for compatibility and support, Juniper occasionally suggests their branded optics.
    • How do I troubleshoot a non-working 1000BASE-SX link?
  • Verify the link settings, compatibility, module seating, fiber polarity, and cleanliness.
    • Is 1000BASE-SX still commonly used today?
  • Yes, particularly for short-distance connectivity in campus, workplace, and legacy data center settings.
    • Is the 1000BASE-SX transceiver backward compatible with 100BASE-FX?
  • No, because of their disparate signaling and speeds, 1000BASE-SX and 100BASE-FX are incompatible.
    • Can I mix 1000BASE-SX with other SFP types on the same switch?
  • Yes, provided that every port is set up correctly and works with the transceiver that is plugged.
