FAQ
What type of cable is the AddOn QSFP-40G-C3M-AO?
The AddOn QSFP-40G-C3M-AO is a QSFP+ direct attach cable (DAC) that uses passive twinax copper cabling. This means it's a copper cable with QSFP+ connectors on both ends that doesn't require active signal conditioning electronics, making it a cost-effective solution for short-distance 40 Gigabit Ethernet connections up to 3 meters.
What network speed does this cable support?
This cable supports 40 Gigabit Ethernet (40GbE) using 40GBase-CU technology. It delivers a maximum data transfer rate of 40 Gbps, providing high-bandwidth connectivity for data-intensive applications in enterprise and data center environments where fast network throughput is essential.
Is this cable compatible with Alcatel-Lucent equipment?
Yes, this cable is specifically compatible with Alcatel-Lucent OmniSwitch 6900 series expansion modules, including the OS-QNI-U3 and OS-HNI-U6 modules. It has been validated for use with these devices, ensuring reliable performance when connecting compatible Alcatel-Lucent network equipment in your infrastructure.
What does TAA compliance mean for this product?
TAA compliance indicates that this product meets the requirements of the Trade Agreements Act, which governs procurement for U.S. government agencies and certain other regulated entities. This compliance ensures the cable can be used in government contracts and other scenarios where adherence to trade agreement regulations is mandatory for procurement.
How long is the cable and what is its reach capability?
This direct attach cable has a length of 3 meters (approximately 9.8 feet). As a passive twinax cable, it's designed for short-reach connections typically within the same rack or between adjacent racks in data center environments. The 3-meter length provides flexibility for most rack-mounted equipment configurations while maintaining signal integrity.
What is the advantage of using a passive twinax cable versus an active optical cable?
Passive twinax cables like the QSFP-40G-C3M-AO offer several advantages for short-distance connections: they require no external power, generate less heat, have lower latency, and are typically more cost-effective than active optical cables. For distances up to 3 meters, passive twinax provides reliable 40GbE connectivity without the complexity and expense of optical transceivers and fiber cabling.
