Description
The HP R6L31A is a high-performance SFP+ (Small Form-factor Pluggable Plus) transceiver module designed to support data rates of 16Gb/s, commonly used in Fibre Channel Storage Area Networks (SANs) and high-speed Ethernet applications. This module is specifically engineered for long-distance communication over single-mode fiber optic cables, enabling reliable data transmission up to 40 kilometers. The SFP+ form factor allows for hot-swappable installation into compatible network switches, host bus adapters (HBAs), and other networking equipment, ensuring minimal disruption during deployment or maintenance. Operating at a precise wavelength of 1531.90nm, this transceiver is often used in conjunction with DWDM (Dense Wavelength Division Multiplexing) systems, although it can also be used in point-to-point links. The use of single-mode fiber is critical for achieving the specified 40km reach, as it minimizes signal degradation over long distances. The module terminates with an LC connector, which is a standard, compact fiber optic connector widely adopted in the industry for its reliability and ease of use. The R6L31A is a crucial component for extending SAN connectivity between data centers, connecting remote storage arrays, or establishing high-speed links within large campus environments. Its ability to deliver 16Gb/s performance over 40km ensures that storage traffic can be reliably transported without becoming a bottleneck, supporting demanding applications that require low latency and high throughput. This transceiver represents a key element in building resilient and scalable storage and data networking infrastructures.
