Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco 400G QSFP-DD Ultra Long-Haul Coherent Optics Module enables 400G traffic anywhere over dense wavelength division multiplexing amplified networks, and is available in both C-band and L-band.
Cisco has expanded the range of 400G digital coherent QSFP-DD transceivers with the 400G QSFP-DD Ultra Long Haul (ULH) Coherent Optics Module.
The high performance and low power of the 400G QSFP-DD ULH module make it an optimal choice to extend Routed Optical Networking use cases to regional and ultra-long-haul DWDM applications previously dominated by high-power Layer 1 transponder solutions without sacrificing spectral efficiency.
The 400G QSFP-DD ULH module is mechanically compliant with the Quad Small Form Factor Pluggable Double Density (QSFP-DD) Type 2A Module Specification and works within the 24W power envelope supported on all existing 400G-capable Cisco® routers. The module contains a printed circuit board with a 76-contact card-edge electrical interface to external host-side logic. The media interface is a duplex LC connector over single-mode fiber coupled to a 1550-nm and 1595-nm optical fiber carrying coherent signals at up to 118 Gbaud in OpenROADM 7.0 compliant mode. In addition, the module offers multiple 400G application select codes optimized for 75 GHz to 112.5 GHz channel spacing for higher spectral efficiency or longer reach, as well as a backward-compatible application select code with 400G QSFP-DD ZR+ High-TX power in OpenZR+ Multi-Source Agreement (MSA)-compliant mode. The signaling operates in both C-band and L-band.
The 400G QSFP-DD ULH module is compliant with Common Management Interface Specification (CMIS) 5.3 and Coherent CMIS (C-CMIS) 1.3, and is available for both on Cisco and third-party host platforms.
