About the Cisco DWDM-SFP10G-C-S
The Cisco DWDM-SFP10G-C-S is a hot-swappable SFP+ DWDM tunable 50GHz optical transceiver for 10 Gbps Ethernet / OTN links over single-mode fiber, with an LC interface and reach of up to 70 km. Cisco description: Tunable C-band DWDM SFP+, 96 ch 50GHz, limiting interface (no EDC needed, any SFP+ port). 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, Nexus, ASR / NCS router and UCS platforms.

DWDM-SFP10G-C-S: frequently asked questions
What is the Cisco DWDM-SFP10G-C-S?
The DWDM-SFP10G-C-S is an SFP+ DWDM tunable 50GHz module for 10 Gbps Ethernet / OTN links. It is used for 10G uplinks, distribution / core links, metro aggregation and DWDM / OTN client ports on Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms.
What is the maximum distance of the DWDM-SFP10G-C-S?
Cisco documentation lists the DWDM-SFP10G-C-S for 70km.
Which fiber and connector does the DWDM-SFP10G-C-S need?
The DWDM-SFP10G-C-S uses an LC connector on single-mode fiber (OS2). Wavelength: tunable C-band 1528.77-1566.72 nm. 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 DWDM-SFP10G-C-S?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the DWDM-SFP10G-C-S for 25 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.
What does the -S at the end of DWDM-SFP10G-C-S mean?
Cisco uses the -S suffix for its 'S-class' optics: the same IEEE standard as the full version, built for enterprise and data-center switches. Service-provider routers that need OTN or extended features may need the non -S version, so check the platform list before ordering.
Is your DWDM-SFP10G-C-S 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 DWDM-SFP10G-C-S price in India and how do I order?
The Cisco DWDM-SFP10G-C-S 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.
