About the Cisco FET-10G
The Cisco FET-10G is a hot-swappable SFP+ 10G FEX fabric link optical transceiver for 10 Gbps Ethernet links over multimode fiber, with an LC interface and reach of up to 25 m OM2 / 100 m OM3/OM4/OM5. Cisco description: Fabric Extender Transceiver, Nexus 2000 FEX-to-parent fabric links only (not orderable individually). 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: 10G uplinks, distribution / core links, metro aggregation and DWDM / OTN client ports on Cisco Catalyst campus switches and Nexus data-center switches.

FET-10G: frequently asked questions
What is the Cisco FET-10G?
The FET-10G is an SFP+ 10G FEX fabric link module for 10 Gbps Ethernet links. It is used for 10G uplinks, distribution / core links, metro aggregation and DWDM / OTN client ports on Cisco Catalyst campus switches and Nexus data-center switches.
What is the maximum distance of the FET-10G?
Cisco documentation lists the FET-10G for 25m OM2 / 100m OM3/OM4/OM5.
Which fiber and connector does the FET-10G need?
The FET-10G 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 FET-10G?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the FET-10G for 11 Cisco device families (for example Cisco Catalyst campus switches and Nexus data-center switches). 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 FET-10G 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 FET-10G price in India and how do I order?
The Cisco FET-10G 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.
