Cisco DWDM-SFP10G-58.98
10GBASE-DWDM 1558.98 nm SFP10G (100-GHz ITU grid), Original Cisco
Product Highlights
As enterprises and service providers scale their optical transport networks, the need for reliable, standards-based DWDM optics becomes critical. The Cisco DWDM-SFP10G-58.98 is an original Cisco 10GBASE-DWDM SFP+ transceiver module operating at a fixed wavelength of 1558.98 nm on the 100-GHz ITU C-band grid.
Designed for deployment in Cisco switches, routers, and optical transport platforms, this module supports multi-rate data transmission from 9.9 Gbps to 11.1 Gbps, covering 10 Gigabit Ethernet LAN, WAN, and OTU2/OTU2e applications. With reach of up to 80 km over single-mode fiber, it is ideal for metro-area, campus-interconnect, and regional backbone links where distance and wavelength density matter.
The DWDM-SFP10G-58.98 features Digital Optical Monitoring (DOM) for real-time diagnostics, an LC duplex connector, and a hot-swappable design that enables non-disruptive installation and replacement. As a genuine Cisco module, it supports the Cisco quality identification (ID) feature, ensuring the host platform recognizes and validates the transceiver for full operational confidence. This module is part of Cisco's family of 40 fixed-wavelength DWDM SFP+ transceivers, enabling pay-as-you-grow wavelength provisioning across your DWDM infrastructure.
Features & Benefits
DWDM Fixed Wavelength Precision
Operating at a fixed 1558.98 nm wavelength on the 100-GHz ITU C-band grid, this transceiver delivers precise channel assignment for dense wavelength-division multiplexing. It is one of 40 non-tunable ITU wavelengths in the Cisco DWDM SFP+ family, enabling operators to incrementally add channels as bandwidth demands grow — a true pay-as-you-grow model.
Multi-Rate 10G Flexibility
The module supports data rates from 9.9G to 11.1G, accommodating 10 Gigabit Ethernet LAN, 10G WAN, and OTU2/OTU2e optical transport network protocols. This multi-rate capability means a single optic can serve diverse application requirements across your network without swapping hardware.
Extended 80 km Reach
With up to 80 km reach over single-mode fiber, the DWDM-SFP10G-58.98 bridges metro-area and regional distances without the need for intermediate signal regeneration. This reduces infrastructure cost and simplifies network topology for long-haul 10G links.
Digital Optical Monitoring (DOM)
Built-in DOM support provides real-time visibility into critical operating parameters such as optical transmit/receive power, temperature, laser bias current, and supply voltage. This enables proactive fault detection, faster troubleshooting, and improved network uptime.
Hot-Swappable & Cisco Quality ID
The SFP+ form factor is hot-swappable, allowing field installation or replacement without powering down the host device. As an original Cisco module, it supports the Cisco quality identification (ID) feature, so the host switch or router can verify the transceiver is certified and tested by Cisco.
Deployment Scenarios
Metro & Regional DWDM Transport
Deploy the DWDM-SFP10G-58.98 in metro-area and regional backbone links where multiple 10G wavelengths must traverse a single fiber pair over distances up to 80 km. Pair with a DWDM MUX/DEMUX to maximize fiber utilization and reduce leased-fiber costs.
Data Center Interconnect (DCI)
Connect geographically separated data centers over dark fiber using DWDM wavelengths. The 1558.98 nm channel can coexist with dozens of other wavelengths on the same fiber, enabling high-capacity, low-latency inter-site replication and disaster recovery links.
Service Provider 10G WAN / OTN Services
Service providers can leverage the module's OTU2/OTU2e support to deliver managed 10G wavelength services to enterprise customers. The fixed wavelength simplifies channel planning, while DOM provides the monitoring visibility needed for SLA assurance.
Enterprise Campus Backbone Extension
For large campus or multi-building environments with fiber runs exceeding standard 10G reach, this DWDM SFP+ provides a cost-effective way to extend 10 Gigabit Ethernet connectivity without deploying additional active equipment.
