Cisco 10G DWDM XFP 1542.94nm 100GHz Optical Transceiver

• 10G DWDM wavelength deployment across compatible Cisco optical networking infrastructure.
• Replacement of an existing Cisco DWDM XFP operating at the 1542.94 nm wavelength.
• Optical network expansion where an additional wavelength is required on an existing DWDM architecture.
• Maintenance of wavelength-specific optical links in enterprise and service-provider environments.
• Network modernization projects retaining compatible legacy Cisco optical platforms.
• Metro and long-distance optical connectivity where a defined DWDM wavelength is part of the network design.
• Capacity expansion for optical transport infrastructure without changing the established wavelength plan.
• Spare-part provisioning for operational continuity and faster replacement of failed or aging optical modules.
• Telecommunications infrastructure requiring Cisco 10GBASE-DWDM XFP connectivity.
• Lifecycle replacement programs where procurement teams need an exact wavelength and form-factor match.

• 10GBASE-DWDM optical transceiver for wavelength-division multiplexed networking.
• XFP form factor for compatible Cisco 10G optical interfaces.
• 1542.94 nm center wavelength for wavelength-specific DWDM deployment.
• 100-GHz ITU DWDM grid specification.
• Designed for 10G optical network connectivity.
• Fixed wavelength selection simplifies matching against an established DWDM channel plan.
• Useful for targeted optical link replacement and infrastructure maintenance.
• Supports procurement of an exact-model optical module where platform and wavelength compatibility are already established.
• Suitable for optical network expansion within compatible DWDM architectures.
• Helps preserve existing optical infrastructure investment when an exact replacement is required.
• Applicable to enterprise, telecommunications, carrier, and service-provider optical environments.
• Provides a focused upgrade path for compatible legacy 10G DWDM infrastructure.
• Can support spare inventory planning for business continuity and maintenance requirements.
• Lifecycle procurement should include availability and platform-support verification because Cisco has published end-of-life information for the DWDM XFP family.

• Why Choose This Product?

• Organizations choose the Cisco DWDM-XFP-42.94 when an existing optical design specifically requires the 1542.94 nm DWDM wavelength in an XFP interface. Its value is less about generic 10G connectivity and more about obtaining the correct wavelength, grid specification, and form factor for a compatible optical platform. Compared with nearby DWDM-XFP variants, the 1542.94 nm wavelength provides a distinct position within the wavelength plan, helping buyers avoid mismatched optical modules. It can be particularly valuable for exact-model replacements, maintenance spares, and controlled network expansion where changing the optical architecture would add cost or operational risk. Buyers should validate the host Cisco platform, optical system design, and current availability before procurement, especially because Cisco has published lifecycle information for this DWDM XFP family.
