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 ER1 optical module enables 400GbE router to router traffic over dark fiber up to a 45 km distance.
Cisco has expanded the range of 400G digital coherent QSFP-DD transceivers with the Cisco® 400G QSFP-DD ER1 optical module. Leveraging coherent technology innovations, the QSFP-DD ER1 optical module can transmit a single wavelength of 400G traffic directly from a router port up to a 45 km distance. The 400G QSFP-DD ER1 optical module’s small size and low power consumption make it an optimal choice for unamplified point-to-point dark fiber applications including data center interconnect, campus interconnect, wireless backhaul, and metro access/aggregation.
The Cisco 400G QSFP-DD ER1 optical module is mechanically compliant to the QSFP-DD Multi-Source Agreement (MSA). The QSFP-DD module contains a PCB with a 76 contact card-edge electrical interface to external host-side logic. The media interface is a duplex LC connector operating in C-band over single-mode fiber (SMF) carrying 400G 16 QAM coherent signal.
