Axiom R9X54A-AX
Aruba Compatible 10GBASE-BX40-D SFP+ LC 40km Downstream Transceiver
A high-quality downstream transceiver for 10G Ethernet over 40km of single-mode fiber.
Overview :
The Axiom R9X54A-AX is a high-quality 10GBASE-BX40-D SFP+ transceiver engineered for Aruba-compatible networking equipment. This downstream transceiver provides efficient 10 Gigabit Ethernet connectivity over single-mode fiber optic cables with a maximum reach of 40 kilometers, making it an ideal solution for extended enterprise and telecom fiber network applications. It is a reliable and cost-effective alternative to OEM modules for long-distance links.
Features :
Operating on single-mode fiber, the R9X54A-AX transceiver employs bi-directional transmission technology, using a 1330nm wavelength for transmitting data downstream and 1270nm for receiving upstream signals. This approach enables data transmission over a single fiber strand while minimizing fiber infrastructure requirements. The hot-swappable SFP+ module fits standard SFP+ slots, facilitating easy network equipment upgrades and maintenance without service interruption. Its simplex LC connector ensures compatibility with industry-standard fiber cabling systems used in metro and long-haul fiber optic networks. Designed to comply with IEEE 802.3ae standards and Aruba OEM-specific requirements, the transceiver guarantees reliable interoperability and uptime in fiber network backbones, campuses, and data center environments requiring stable long-distance links.
