Hirschmann MM20-Z6Z6Z6Z6SAHH Industrial Ethernet Media Module

This media module serves as a critical component for industrial networks requiring high-speed fiber connectivity. Designed for harsh environments, it provides four 100Mbps fiber ports with SFP sockets, ensuring stable data transmission in automation systems where reliability is non-negotiable.

Engineers often deploy this module in manufacturing lines, energy grids, and transportation systems where network downtime could disrupt operations. A plant manager in Germany reported using it to upgrade an aging rail signaling system, leveraging its DIN rail design for quick integration. The MM20 series also includes modules like the MM20-Z6Z6Z6Z6SAHH’s sibling models with copper ports or mixed media configurations, offering flexibility for system upgrades.

Redundancy is a key strength—this module supports ring topologies with Hirschmann switches, reducing single points of failure. The SFP sockets allow hot-swapping of transceivers for fiber type conversion without shutting down the network. While power consumption details aren’t published, its passive cooling design minimizes maintenance in high-temperature settings. Compatibility with both managed and unmanaged switches makes it adaptable to legacy systems, though some technicians note that firmware updates require careful planning during maintenance windows.
