Frequently Asked Questions
What is the primary function of the Aruba JL307A 100G DAC cable? +
The Aruba JL307A is a high-speed Direct Attach Copper (DAC) cable designed for short-reach interconnects between 100G-enabled switches and routers. It serves as a cost-effective alternative to optical transceivers for intra-rack or inter-rack connections, facilitating high-bandwidth, low-latency data transmission within high-density enterprise data center environments.
What type of connector interfaces does the JL307A use? +
The JL307A features QSFP28 to QSFP28 connectors on both ends. This interface is the industry standard for 100 Gigabit Ethernet applications, ensuring full compatibility with Aruba and third-party networking equipment that supports the QSFP28 form factor. It enables a plug-and-play connection without the need for additional transceiver modules.
What is the maximum cable length for the Aruba JL307A? +
This specific model is a 3-meter (approximately 10 feet) cable. Due to the physical limitations of copper transmission at 100G speeds, DAC cables are designed for short-range deployments, typically within a single server cabinet or across adjacent racks to minimize signal degradation and latency.
Can the JL307A DAC cable be used for 10G or 40G networking ports? +
While the physical QSFP28 connector is backward compatible with QSFP+ ports in terms of size, the performance and signal encoding differ. The JL307A is optimized specifically for 100G throughput. Utilizing it in a 40G port may require specific switch configuration, though it is primarily intended for native 100G high-performance networking environments.
Does the Aruba JL307A require specific software licensing or configuration? +
The JL307A is a passive copper cable assembly, meaning it does not require active power or specific software licenses to operate. Once plugged into a supported 100G QSFP28 port, the host switch will recognize the cable hardware automatically, allowing for seamless integration into your existing network fabric without complex setup procedures.
In what deployment scenarios is a DAC cable preferred over optical fiber? +
Direct Attach Copper cables like the JL307A are ideal for Top-of-Rack (ToR) deployments where high-speed links are needed over very short distances. They are more energy-efficient than optical solutions because they do not require additional power for optical conversion, and they provide significant cost savings when connecting hardware located in the same or adjacent racks.
How does the JL307A impact network latency compared to active optical cables? +
Because the JL307A utilizes copper conductors to transmit electrical signals directly, it provides extremely low latency by eliminating the need for signal conversion between electrical and optical formats. This makes it an excellent choice for latency-sensitive applications such as High-Performance Computing (HPC) clusters or high-frequency trading networks.
What thermal considerations should be managed when using the JL307A? +
As a passive DAC cable, the JL307A generates virtually no heat, which is a major advantage for dense port deployments. Unlike optical transceivers, which consume power and generate localized heat at the port interface, this cable helps maintain lower overall port temperatures, contributing to a more stable and efficient operating environment for your switch.
How can I obtain a bulk quote for multiple Aruba JL307A units? +
