RSPM20-4Z64Z6SZ9HHS9 – 8-Port SFP Fibre Expansion Module by Hirschmann

The Hirschmann RSPM20-4Z64Z6SZ9HHS9 is a Fast Ethernet media module from Hirschmann’s RSPM expansion series, designed specifically to add eight SFP fibre slots to RSPE series switches, bringing the total port count from the 12-port base unit up to 28 ports with a fully fibre-connected expansion block. Unlike the mixed copper/fibre variant, this module provides an all-SFP port configuration, making it the preferred choice for electrically noisy industrial environments — such as variable speed drive areas, high-voltage switchgear rooms, and large motor installations — where fibre’s inherent EMI immunity is essential for reliable data transmission. The module is powered internally via the host RSPE32 or RSPE37 switch variant, with a 12 W power draw and no additional wiring required for installation. Compatible SFP modules span single mode, single mode long-haul, and multimode fibre types to suit varying distance requirements from panel-to-panel runs to inter-building links. Operating from 0 to +60°C with IEC 60068-2-6 vibration and IEC 60068-2-27 shock compliance, and approved to CE, FCC, RCM, EN 61131, and EN 60950, the RSPM20-4Z64Z6SZ9HHS9 is a reliable and straightforward expansion component for manufacturing, process, and utility network architects working with RSPE modular platforms across Nordic and Baltic industrial markets.
