About the Cisco CWDM-SFP-XXXX
The Cisco CWDM-SFP-XXXX is a hot-swappable SFP IEEE 1000BASE-X optical transceiver for 1 Gbps Ethernet links over single-mode fiber, with an LC interface and reach of up to 100 km. This is a family entry: Cisco orders these optics by the exact channel or wavelength, so the x characters in the part number are replaced by the ITU channel / CWDM wavelength you need. 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 campus switches and Nexus data-center switches.

CWDM-SFP-XXXX: frequently asked questions
What is the Cisco CWDM-SFP-XXXX?
The CWDM-SFP-XXXX is an SFP IEEE 1000BASE-X 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 campus switches and Nexus data-center switches.
What is the maximum distance of the CWDM-SFP-XXXX?
Cisco documentation lists the CWDM-SFP-XXXX for 100km.
Which fiber and connector does the CWDM-SFP-XXXX need?
The CWDM-SFP-XXXX uses an LC connector on single-mode fiber (OS2). Wavelength: CWDM 1470–1610 nm (one wavelength per part number). Both ends of the link must use the same optical standard. CWDM / DWDM optics must match the channel of the mux / demux port and the far-end module.
Which Cisco devices support the CWDM-SFP-XXXX?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the CWDM-SFP-XXXX for 97 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.
How do I order the right CWDM-SFP-XXXX channel?
Replace the x characters with the ITU channel or CWDM wavelength used on your mux / demux port (for example the channel printed on the mux port label). Tell us the channel list and quantity per channel and we quote each exact part number.
Is your CWDM-SFP-XXXX 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 CWDM-SFP-XXXX price in India and how do I order?
The Cisco CWDM-SFP-XXXX 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.
