About the Cisco ONS-SI-GE-SX
The Cisco ONS-SI-GE-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 220-550 m MMF. Cisco description: ONS 1000BASE-SX SFP, industrial temp for ML1000-2 / ML-MR-10 / CE-MR-10 / CE-MR-6. 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 ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards.

What is the maximum distance of the ONS-SI-GE-SX?
Cisco documentation lists the ONS-SI-GE-SX for 220-550m MMF.
Which fiber and connector does the ONS-SI-GE-SX need?
The ONS-SI-GE-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 ONS-SI-GE-SX?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the ONS-SI-GE-SX for 10 Cisco device families (for example Cisco ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards). 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 ONS-SI-GE-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 ONS-SI-GE-SX price in India and how do I order?
