In addition to six RJ-45-ports, the FL Switch SMN 6TX/2POF-PN from Phoenix Contact offers two POF interfaces with diagnostics capabilities in narrow control cabinet-friendly housing. Both polymer and HCS fibers can be connected via the fiber-optic interfaces with SCRJ connections. Combining the switch with the field assembly-capable HCS fibers, with gradient index FL FOC PN-C-HCS-GI-200/230, enables transmission distances of up to 250m. The fiber-optic cable connectors are assembled on site in <2 min without requiring crimping, gluing or polishing. The switch can be used as a Profinet I/O device and in redundant Ethernet networks. Using the integrated fiber-optic diagnostics, it supports users when troubleshooting faults, whereby the received power is continually measured and the optical system reserve is displayed in the Web-based management system using an SNMP object or Profinet communication. The switch can be used as a Profinet IO device with a PDEV function and can be utilized in redundant Ethernet networks with RSTP Fast Ring Detection or in an MRP environment. For Ethernet/IP networks, it has multicast filtering with an IGMP snooping function. A connection to high performance switches in the backbone area, such as the company’s Gigabit Modular FL Switch GHS 12G/8, can be established not just via copper interfaces but also via POF-SCRJ interfaces using GIHCS fiber-optic cable.
