The prestigious South Korean firm HiFi ROSE has just expanded its powerful ecosystem in high-performance portable and stationary audio with the addition of a very special component: the center of distribution (“hub”) USB signals via optical RSA720. A refined product created with the purpose of block potential vibrations mechanical and electrical noise from external mass storage devices and thus provide a optimal solution for their reliable use. There are many qualities that make this sophisticated accessory a product that makes a difference, the first of which is a compact format in order to maximize usability and functionality and the commitment to durable materials in its construction, with the aim of maximizing the reliability long-term.
But the key to the RSA720 lies without a doubt in a complex engineering based on cutting-edge connectivity strategies, materialized in the use of SFP optical transceivers (acronym for “Small Form-Factor Pluggable” or Compact Format Pluggable), commonly used in data communications and telecommunications and that support, among other standards, the Fiber Channel and Gigabit Ethernet. Because of this, the RSA270 is very useful when working with high-speed and highly robust USB connections (those common in the “Hi-Res” sound field) in situations where data transmission over long distances is required. In practical terms, the new HiFi ROSE is equipped with a USB 3.0 Type-B input and one 10G SFPto which are added two output ports USB 3.0 and two other USB 2.0, allowing the user to plug and use external devices without having to install a separate driver.
In this sense, it must be emphasized that the main advantage of the architecture used is that harness the power of fiber optics in parameters such as distance (which depending on the chosen module can be extended without loss of stability up to several hundred meters), maintaining speed of the USB standard. A switch slider located on one of the side panels of the RSA720 allows you to select between two operating modes: on the one hand, the “SFP Mode” with the two SFP modules and the SFP optical cable supplied as standard (this would be the case of the ROSE RS130 HiFi streaming “transport”), and, on the other hand, the “Type-B Mode” if the connected device does not support the SFP optical transceiver.
