Aruba-branded transceivers ensure firmware-level compatibility, optimized power negotiation, and adherence to platform-specific thermal and electrical tolerances, which differentiates them from generic or third-party alternatives within the same category.

Key Characteristics of 10GBase-T Copper SFP+ Transceivers

The technical foundation of the 10GBase-T copper SFP+ transceiver category is defined by IEEE 802.3an standards, which specify the requirements for transmitting 10 Gigabit Ethernet over balanced twisted-pair copper cabling. Modules such as the HPE 1990-4815 implement advanced digital signal processing to manage crosstalk, attenuation, and noise inherent in copper media at high frequencies. This capability allows consistent 10 Gbps throughput across CAT6A cabling runs up to 30 meters, making them suitable for dense equipment racks and short interconnects.

Power consumption is an important technical consideration within this category. Copper-based 10GBase-T transceivers generally consume more power than optical SFP+ modules due to the complexity of signal processing. Aruba designs its modules to operate within the thermal budgets of supported switches, ensuring stable performance even in high-density port configurations. The 1990-4815 transceiver reflects this balance by delivering reliable 10 Gigabit speeds while conforming to Aruba’s strict power and heat dissipation guidelines.

RJ-45 Interface and CAT6A Cable Compatibility

A defining feature of this transceiver category is the use of a standard RJ-45 connector, which allows direct attachment of CAT6A copper Ethernet cables. This eliminates the need for specialized fiber connectors or patch cords and simplifies installation for network administrators. The Aruba 10GBase-T SFP+ transceiver category is optimized specifically for CAT6A cabling to ensure compliance with 10 Gigabit Ethernet specifications, minimizing latency and packet loss over supported distances.

CAT6A cabling provides enhanced shielding and performance characteristics compared to earlier copper standards, which is essential for maintaining signal integrity at 10 Gbps. The Aruba 1990-4815 module leverages these characteristics to deliver stable links in electrically noisy environments such as data centers with high equipment density. This compatibility makes the category particularly attractive for organizations standardizing on CAT6A as part of structured cabling strategies.

Hot-Pluggable SFP+ Form Factor Advantages

The SFP+ form factor is integral to the flexibility offered by this transceiver category. Hot-pluggable design allows network operators to install or replace modules without powering down switches, reducing maintenance windows and improving overall uptime. The Aruba 1990-4815 transceiver is engineered to meet these expectations, supporting live insertion and removal while maintaining link stability and protecting switch hardware.

From a physical standpoint, the compact dimensions of SFP+ modules enable high port density on Aruba switches. This density is critical in aggregation and top-of-rack scenarios where space efficiency directly impacts scalability. By combining the SFP+ form factor with RJ-45 connectivity, this category provides a unique blend of density and compatibility that supports incremental network evolution.
