Cisco DWDM-SFP10G-33.47
10GBASE-DWDM 1533.47 nm SFP10G (100-GHz ITU grid), Original Cisco
Product Highlights
As metro and long-haul networks scale to meet surging bandwidth demands, maximizing fiber utilization becomes critical. The Cisco DWDM-SFP10G-33.47 is an original Cisco 10GBASE-DWDM SFP+ transceiver module operating at a fixed wavelength of 1533.47nm (ITU Channel C55) on the 100-GHz ITU grid. It enables enterprises and service providers to integrate Dense Wavelength-Division Multiplexing transport directly into Cisco 10 Gigabit Ethernet switches, routers, and optical transport platforms.
This hot-swappable SFP+ module supports data rates from 9.9G to 11.1G, covering 10 Gigabit Ethernet LAN, WAN (OC-192/STM-64), and OTU2/OTU2e applications. It connects via a standard LC duplex interface over single-mode fiber and includes Digital Optical Monitoring (DOM) for real-time insight into operating parameters such as optical power, temperature, and supply voltage.
As a genuine Cisco transceiver, the DWDM-SFP10G-33.47 supports the Cisco quality identification (ID) feature, ensuring automatic recognition and validation on compatible Cisco platforms. With a maximum power consumption of just 1.5W and a commercial operating temperature range of 0°C to 70°C, it is engineered for reliable, energy-efficient operation in enterprise data centers, service provider points of presence, and metropolitan-area DWDM rings.
Features & Benefits
Dense Wavelength-Division Multiplexing
The DWDM-SFP10G-33.47 operates on the 100-GHz ITU grid at 1533.47nm (Channel C55), enabling multiple 10G channels to be multiplexed onto a single fiber pair using standard DWDM mux/demux equipment. This dramatically increases fiber capacity and reduces the cost of leasing or deploying additional fiber strands.
Multi-Rate 10G Support
Supporting data rates from 9.9G to 11.1G, this module accommodates 10 Gigabit Ethernet (LAN), 10G WAN (OC-192/STM-64), and OTU2/OTU2e optical transport network protocols. This versatility lets you deploy a single transceiver type across LAN, WAN, and OTN use cases.
Digital Optical Monitoring (DOM)
Built-in DOM provides real-time access to critical operating parameters — including optical TX/RX power, laser bias current, module temperature, and supply voltage — via a standard 2-wire serial interface (SFF-8472). This enables proactive fault detection and simplifies troubleshooting before issues impact traffic.
Hot-Swappable & Low Power
The SFP+ form factor is hot-swappable, allowing field replacement without disrupting other ports or requiring a maintenance window. With a maximum power consumption of just 1.5W, it minimizes thermal impact in high-density line card deployments.
Cisco Quality Identification
As an original Cisco transceiver, this module supports the Cisco quality ID feature, enabling the host switch or router to automatically verify that the optic is a Cisco-certified and tested module. This ensures full compatibility and access to Cisco TAC support.
Deployment Scenarios
Metropolitan DWDM Ring
Deploy the DWDM-SFP10G-33.47 in metro-area DWDM rings to deliver 10G services between central offices, data centers, and aggregation sites. By assigning each link a unique ITU channel, you maximize fiber utilization across the ring without costly new fiber builds.
Enterprise Campus or Data Center Interconnect
Use this transceiver to establish high-capacity 10G DWDM links between campus buildings or data center facilities over existing single-mode fiber. DWDM multiplexing allows multiple 10G connections to share a single fiber pair, reducing infrastructure costs.
Service Provider WAN / OTN Backhaul
Service providers can leverage the module's multi-rate support (LAN, WAN, OTU2/OTU2e) to deliver 10G backhaul services over their DWDM optical transport network. The fixed C55 wavelength integrates seamlessly into existing ITU grid channel plans.
