About the Cisco ONS-SC-2G-28.7
The Cisco ONS-SC-2G-28.7 is a hot-swappable SFP OC-48/STM-16/GE DWDM ITU ch 61 optical transceiver for 2.5 Gbps SONET/SDH links over single-mode fiber, with an LC interface and reach of up to DWDM system-dependent. Cisco description: ONS DWDM SFP OC-48/STM-16/GE, 100 GHz. 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: OC-48 / STM-16 transport, GPON access and multirate client links on Cisco ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards.

ONS-SC-2G-28.7: frequently asked questions
What is the Cisco ONS-SC-2G-28.7?
The ONS-SC-2G-28.7 is an SFP OC-48/STM-16/GE DWDM ITU ch 61 module for 2.5 Gbps SONET/SDH links. It is used for OC-48 / STM-16 transport, GPON access and multirate client links on Cisco ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards.
What is the maximum distance of the ONS-SC-2G-28.7?
Cisco documentation lists the ONS-SC-2G-28.7 for DWDM system-dependent.
Which fiber and connector does the ONS-SC-2G-28.7 need?
The ONS-SC-2G-28.7 uses an LC connector on single-mode fiber (OS2). Wavelength: DWDM 1528.77 nm (ch 61). 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 ONS-SC-2G-28.7?
The ONS-SC-2G-28.7 is documented for Cisco ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards. 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 ONS-SC-2G-28.7 still available?
Cisco has announced end-of-sale for the ONS-SC-2G-28.7. Cisco's notice: Cisco bulletin EOL15433, end-of-sale 31-Jul-2025, 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 ONS-SC-2G-28.7 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-SC-2G-28.7 price in India and how do I order?
The Cisco ONS-SC-2G-28.7 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.
