About the Cisco ONS-SC-155-EL
The Cisco ONS-SC-155-EL is a hot-swappable SFP STM-1e electrical copper module for 155 Mbps SONET/SDH links over copper cable, with a Coax interface and reach of up to coax. Cisco description: ONS OC-3/STM-1 electrical (STM-1e, 155 Mbps coax) SFP, commercial temp. 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-3 / STM-1 SONET/SDH and optical service-channel links on Cisco ONS 15454 MSTP / NCS 2000, NCS 1000 and NCS 4000 optical-transport cards.

Which cable does the ONS-SC-155-EL use?
It uses a Coax interface with coaxial cable cabling.
Which Cisco devices support the ONS-SC-155-EL?
The ONS-SC-155-EL 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 your ONS-SC-155-EL 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-155-EL price in India and how do I order?
The Cisco ONS-SC-155-EL 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.
