Cisco ONS-SC+-10G-C
SFP+ -10G MR, Full C Band Tuneable DWDM SFP+, 50 Ghz, LC, Original Cisco
Product Highlights
Managing a large inventory of fixed-wavelength DWDM optics across a metro or regional network is costly, complex, and slow. Every wavelength change means a truck roll and a different part number on the shelf. The Cisco ONS-SC+-10G-C eliminates that burden with a single, full C-Band tunable DWDM SFP+ transceiver that covers all 96 ITU-T 50 GHz channels.
This original Cisco multirate (MR) SFP+ module delivers 10 Gbps connectivity over single-mode fiber at distances up to 80 km, supporting a wide range of protocols including 10 Gigabit Ethernet, OC-192/STM-64, OTU2/OTU2e, and 8G Fibre Channel. Its tunable laser can be software-provisioned to any channel across the 1528.77–1566.72 nm wavelength range, enabling rapid service activation and dramatically reducing the number of spare optics you need to stock.
Designed for the Cisco ONS platform family, the ONS-SC+-10G-C plugs into SFP+ slots on cards such as the 15454-ADM-10G, 15454-10GE-XP, and 15454-GE-XPE. Built-in digital optical monitoring (DOM) provides real-time diagnostics, while the hot-swappable design allows installation and replacement without powering down the host equipment. For service providers and enterprises operating DWDM transport networks, this transceiver delivers the tunability, reach, and multirate versatility needed to future-proof optical infrastructure while keeping operational costs in check.
Features & Benefits
Full C-Band Wavelength Tunability
The ONS-SC+-10G-C is tunable across 96 ITU-T 50 GHz channels spanning the full C-Band (approximately 1528.77–1566.72 nm). This means a single part number replaces dozens of fixed-wavelength optics, reducing sparing inventory by up to 95% and enabling rapid, software-driven wavelength provisioning without a site visit.
10G Multirate Flexibility
As a multirate (MR) transceiver, this module supports OC-192, STM-64, 10 Gigabit Ethernet, OTU2/OTU2e, and 8G Fibre Channel data rates. This protocol versatility lets you deploy a single optic across diverse service types — from legacy SONET/SDH transport to modern Ethernet and OTN — protecting your investment as traffic profiles evolve.
Extended 80 km Reach
With ZR-class optics rated for up to 80 km over standard single-mode fiber, the ONS-SC+-10G-C is ideal for metro-core and regional DWDM rings. The extended reach reduces or eliminates the need for intermediate amplification on many spans, lowering both capital and operational costs.
Digital Optical Monitoring (DOM)
Integrated DOM/DDM provides real-time monitoring of critical parameters including module temperature, supply voltage, laser bias current, and transmit/receive optical power. Proactive visibility into transceiver health enables faster troubleshooting and helps prevent service-affecting failures before they occur.
Hot-Swappable SFP+ Design
The compact SFP+ form factor delivers the industry's highest 10G port density per chassis slot. Hot-swap capability means you can install or replace the module without powering down the host card, minimizing maintenance windows and maximizing network uptime.
Deployment Scenarios
Metro & Regional DWDM Transport
Deploy the ONS-SC+-10G-C on Cisco ONS 15454 MSTP transponder and muxponder cards to carry 10G services across metro-core and regional DWDM rings. Full C-Band tunability enables rapid wavelength assignment on ROADM-based networks, while 80 km reach covers most metro spans without amplification.
Simplified Optical Sparing Strategy
Replace an entire shelf of fixed-wavelength DWDM SFP+ modules with a single tunable part number. The ONS-SC+-10G-C dramatically reduces spare inventory costs and logistics complexity, ensuring any failed optic can be replaced immediately regardless of the channel it serves.
Multi-Protocol 10G Aggregation
Leverage multirate support to aggregate diverse 10G client services — 10GbE, OC-192/STM-64, OTU2, and 8G FC — onto a common DWDM transport layer. This is ideal for service providers offering managed wavelength services to enterprise customers with mixed traffic profiles.

This is an ONS-family SFP+ transceiver designed for Cisco ONS 15454 MSTP/MSPP platforms. It requires a host card with an SFP+ port that supports tunable DWDM provisioning. The ONS-SC+ prefix distinguishes it from the DWDM-SFP10G-C, which is intended for Cisco routing and switching platforms. Always verify card and software compatibility for your specific deployment before ordering.
