About the Cisco SFP-1G-SX
The Cisco SFP-1G-SX is a hot-swappable SFP 1000BASE-SX optical transceiver for 1 Gbps Ethernet links over multimode fiber, with an LC interface and reach of up to per 1000BASE-SX. Cisco description: 1000BASE-SX SFP for 10G-capable (SFP+) ports only (not 1G-only ports), COM temp, DOM, 2 W. Cisco IOS XE, NX-OS, IOS XR and ONS software read the Cisco coding at insertion, so a genuine module avoids 'unsupported transceiver' messages. Typical uses: Gigabit uplinks, campus and inter-building fiber, access and WAN hand-off links on Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms.

SFP-1G-SX: frequently asked questions
What is the Cisco SFP-1G-SX?
The SFP-1G-SX is an SFP 1000BASE-SX module for 1 Gbps Ethernet links. It is used for Gigabit uplinks, campus and inter-building fiber, access and WAN hand-off links on Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms.
What is the maximum distance of the SFP-1G-SX?
Cisco documentation lists the SFP-1G-SX for per 1000BASE-SX (220m-1000m MMF).
Which fiber and connector does the SFP-1G-SX need?
The SFP-1G-SX uses an LC connector on multimode fiber (OM3/OM4). Wavelength: 850 nm. Both ends of the link must use the same optical standard.
Which Cisco devices support the SFP-1G-SX?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the SFP-1G-SX for 5 Cisco device families (for example Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms). Support depends on the exact line card and software release, so send us your device model and release and we check the matrix before dispatch.
Is your SFP-1G-SX genuine Cisco?
Yes. Next Gen Networks supplies original Cisco parts, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch and we share serial numbers on request so you can verify them in 'show inventory' / the transceiver page. If you want a lower-cost Cisco-coded compatible module for non-critical links, ask us and we quote both options.
What is the SFP-1G-SX price in India and how do I order?
The Cisco SFP-1G-SX price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
