EX-QSFP-40GE-DAC-1M-AO - AddOn EX-QSFP-40GE-DAC-1M-AO 40GBase-CU QSFP+ DAC | US IT Hardware

Product overview

The AddOn Networks EX-QSFP-40GE-DAC-1M-AO is a TAA-compliant 40GBase-CU direct attach cable engineered for high-speed datacenter connectivity. This passive twinax copper cable features QSFP+ connectors on both ends and delivers 40-Gigabit performance over a 1-meter (3.3-foot) reach, ideal for short-distance switch-to-server or switch-to-storage connections. The cable is uniquely serialized, programmed, and application-tested for 100% functional compliance with Juniper Networks infrastructure. Manufactured in the USA/UK with ECCN 5A991 classification, it meets federal procurement requirements. The passive design eliminates power consumption concerns while maintaining reliable signal integrity. Compatible with Juniper EX series switches and other 40GBase-CU capable equipment, this cable reduces latency and operational costs compared to active solutions or optical alternatives.

Best for

Datacenter Switching
Connect Juniper EX series switches with 40GBase-CU ports using passive copper DAC technology. The 1-meter length accommodates typical top-of-rack (ToR) switch configurations with minimal latency.
Server-to-Switch Connectivity
Link servers equipped with 40GBase-CU QSFP+ network interface cards to datacenter switches. Passive twinax design eliminates power requirements and reduces total cost of ownership.
Storage Area Networks (SAN)
Deploy in high-speed storage networks requiring 40-Gigabit throughput. The 1-meter reach supports direct connections between storage arrays and network infrastructure.
High-Performance Computing (HPC)
Support compute cluster interconnects with 40GBase-CU performance. TAA compliance enables deployment in government and regulated environments.
Network Upgrades & Migrations
Replace legacy 10GBase connections with 40-Gigabit capacity using existing QSFP+ infrastructure. Passive design ensures compatibility with standard Juniper equipment.

Frequently asked questions

What is the maximum transmission distance for this 40GBase-CU cable?

The EX-QSFP-40GE-DAC-1M-AO supports a maximum reach of 1 meter (3.3 feet) over passive copper twinax media. This distance is optimized for short-reach datacenter interconnects, such as top-of-rack switch-to-server or switch-to-storage connections. For longer distances, active cables or optical solutions are recommended.

Is this cable compatible with non-Juniper equipment?

Yes, this cable features standard QSFP+ connectors and 40GBase-CU technology, making it compatible with any network equipment supporting 40GBase-CU QSFP+ connections. While engineered for Juniper Networks® EX series switches, it works with other vendors' 40GBase-CU capable infrastructure without compatibility issues.

What does 'passive' mean, and why does it matter?

Passive means the cable contains no active electronics or power components—it relies solely on copper conductors for signal transmission. This design eliminates power consumption, reduces failure points, lowers operational costs, and ensures universal compatibility. Passive cables are more reliable and cost-effective than active alternatives for short-distance applications.

Is this cable TAA compliant for government procurement?

Yes, the EX-QSFP-40GE-DAC-1M-AO is TAA (Trade Agreements Act) compliant and manufactured in the USA/UK. It meets federal procurement requirements and is suitable for government contracts, regulated industries, and organizations with compliance mandates. Each cable is uniquely serialized for audit and traceability purposes.

What testing and quality assurance does this cable undergo?

Each cable is uniquely serialized, programmed, and subjected to comprehensive data-traffic and application testing to ensure 100% functional compliance. This testing verifies signal integrity, connector reliability, and compatibility with Juniper equipment before shipment, providing enterprise-grade quality assurance.

Can I use this cable for longer distances if needed?

No, this cable is rated for a maximum 1-meter reach. Using it beyond this distance may result in signal degradation and packet loss. For longer interconnects, consider the 1-foot (0.3m) variant for shorter runs or upgrade to active DAC cables or optical transceivers for extended distances.

What are the export and customs classifications for this cable?

The cable carries ECCN classification 5A991 and HTS harmonized codes: US (8517.62.0090) and UK (85176200). These classifications facilitate international shipping and customs clearance for bulk procurement across regulated markets and government supply chains.
