About the Cisco DWDM-XENPAK-31.12
The Cisco DWDM-XENPAK-31.12 is a hot-swappable XENPAK DWDM ITU ch 58 10GBASE optical transceiver for 10 Gbps Ethernet links over single-mode fiber, with an SC interface and reach of up to 80 km class. Cisco description: Fixed-wavelength 10GBASE-DWDM XENPAK ITU ch 58 (100GHz grid, 8W), Cisco 10GBase DWDM XENPAK Modules data sheet. 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.

DWDM-XENPAK-31.12: frequently asked questions
What is the Cisco DWDM-XENPAK-31.12?
The DWDM-XENPAK-31.12 is an XENPAK DWDM ITU ch 58 10GBASE 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 DWDM-XENPAK-31.12?
Cisco documentation lists the DWDM-XENPAK-31.12 for 80km class (10dB attenuator on short links).
Which fiber and connector does the DWDM-XENPAK-31.12 need?
The DWDM-XENPAK-31.12 uses an SC connector on single-mode fiber (OS2). Wavelength: DWDM 1531.12 nm (ch 58). 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-XENPAK-31.12?
The DWDM-XENPAK-31.12 is documented for Cisco Catalyst campus switches and Nexus data-center switches. Support depends on the exact chassis, line card and software release; send us your device model and release and we confirm it against Cisco's documentation before dispatch.
Is the DWDM-XENPAK-31.12 still available?
Cisco has announced end-of-sale for the DWDM-XENPAK-31.12. Cisco's notice: end-of-sale 16-Jul-2015, no direct replacement listed. Next Gen Networks sources genuine new and surplus stock on request; tell us the quantity and we confirm availability or quote the current Cisco equivalent.
Is your DWDM-XENPAK-31.12 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-XENPAK-31.12 price in India and how do I order?
The Cisco DWDM-XENPAK-31.12 price in India depends on quantity, delivery city and current stock.
