Add-On QSFP-40G-ESR4-DE-AO QSFP+ Transceiver
Overview
The Add-On QSFP-40G-ESR4-DE-AO is a TAA-compliant QSFP+ transceiver module designed for 40 Gigabit Ethernet (40GbE) networks. It enables long-reach connectivity over single-mode fiber, making it suitable for data center interconnects, campus backbones, and service provider networks where extended distances are required. This module ensures compliance with Trade Agreements Act requirements for government and certain enterprise deployments.
Compatibility
This transceiver is engineered to be compatible with Dell networking equipment supporting QSFP+ modules, including specific models within the Dell PowerSwitch and older Force10 series. Verify compatibility with your specific Dell switch model to ensure seamless integration. It is designed to meet the specifications of Dell's own QSFP-40G-ESR4 module.
Installation Notes
Install the QSFP-40G-ESR4-DE-AO module into a compatible QSFP+ port on your switch. Ensure the fiber optic connectors are clean before mating. The module operates over single-mode fiber (SMF) and supports a maximum link length of 40 kilometers (approximately 24.8 miles). It requires a standard QSFP+ cage and is hot-swappable, allowing for installation or replacement without powering down the switch.
