Frequently Asked Questions

Cisco Compatible 1000BASE-SX SFP Transceiver (SFP-1G-SX)
Frequently Asked Questions (FAQ's)



What is the Cisco Compatible SFP-1G-SX used for?
  • The Cisco Compatible SFP-1G-SX is a small form-factor pluggable (SFP) transceiver used to provide 1 Gigabit Ethernet connectivity over multimode fiber for switches, routers, and network interface cards.
    • Is the SFP-1G-SX hot-swappable?
  • Yes, the Cisco Compatible SFP-1G-SX module is hot-swappable, allowing you to insert or remove it without shutting down the network device.
    • What type of fiber does the SFP-1G-SX support?
  • This module supports multimode fiber (MMF), typically using OM2, OM3, or OM4 fiber types for short-range data transmission.
    • What is the maximum transmission distance of the SFP-1G-SX?
  • The Cisco Compatible SFP-1G-SX supports distances of up to 550 meters over OM2 multimode fiber and up to 1,000 meters over OM3/OM4 MMF using 850nm wavelength.
    • Can the SFP-1G-SX be used with Cisco switches?
  • Yes, this transceiver is fully compatible with a wide range of Cisco switches and routers that support 1G SFP slots.
    • What is the data transfer rate of the Cisco Compatible SFP-1G-SX?
  • It supports data rates of up to 1.25 Gbps, ideal for Gigabit Ethernet applications.
    • Does the SFP-1G-SX support DDM/DOM?
  • Many compatible models include Digital Diagnostics Monitoring (DDM), which allows real-time monitoring of optical parameters such as temperature, voltage, and optical power.
    • What connector type does the SFP-1G-SX use?
  • It uses a standard LC duplex connector, which is widely used for fiber optic connections.
    • Is the SFP-1G-SX compatible with other brands besides Cisco?
  • Yes, while optimized for Cisco devices, this module may also be compatible with other networking equipment that supports SFP modules, depending on the vendor’s coding requirements.
    • Can I use the SFP-1G-SX in both data centers and enterprise networks?
  • Absolutely. The SFP-1G-SX is ideal for high-speed data center interconnects, campus networks, and enterprise LAN applications.
    • What wavelength does the SFP-1G-SX operate on?
  • It operates on an 850nm wavelength, which is standard for short-range multimode fiber optics.
    • How do I install the Cisco Compatible SFP-1G-SX module?
  • Insert the module into the SFP slot of your network device until it clicks into place, then connect the LC fiber cable to the transceiver.
    • Does the SFP-1G-SX support full-duplex communication?
  • Yes, this module supports full-duplex communication for efficient and reliable data transmission.
    • What environments is the SFP-1G-SX suitable for?
  • It is suitable for indoor, climate-controlled environments such as data centers, wiring closets, and network core infrastructures.
    • Is any special configuration needed after inserting the SFP-1G-SX?
  • Generally, no configuration is needed. Once inserted, the switch or router typically auto-detects the transceiver and brings up the link if fiber is connected.
