Connectivity

Industrial Ethernet network infrastructure purpose-built to move process-measurement data — reliably, securely, and in real time — from the instrument to the control room, the historian, and the cloud.

The Challenge

Mining Environments Are Hard on Networks

Process intelligence generates continuous, high-value measurement data. But that data is only useful if it reaches the control room, historian, and analytics systems reliably. Mining environments — with dust, vibration, electromagnetic interference, long physical distances, and demanding cybersecurity expectations — present infrastructure challenges that consumer and commercial networking cannot reliably address.

Larch Networks provides Marvell-based industrial Ethernet switches running Hardened SONiC, engineered for the precision, security, and continuous-uptime requirements of operational technology (OT) networks in mineral processing and adjacent natural-resource industries.

Connectivity Partner

Larch Networks

Marvell-based industrial Ethernet switches with Hardened SONiC NOS. Larch Networks moves field measurement data from sensor to decision — across PoE++ sensor-edge switches, Aldrin2 plant aggregation, and Falcon 25G/100G/400G site backbone — with native PTP time synchronization, SecureIQ multilayer cybersecurity, and uCentral cloud management for remote operations.

Infrastructure Capabilities

Industrial-Grade. Mining-Calibrated.

Sensor Edge — PoE++

AC5X-family switches deliver up to 1900 W of PoE++ (802.3bt) on 24× / 48× 1G or 2.5G ports — powering and connecting the measurement system and IP-based field instruments on a single cable, with 10G / 25G uplinks back to the plant fabric.

Plant Aggregation

Marvell Aldrin2 switches (24×–48× 10G + 6× 100G) aggregate sensor traffic at the control room and feed SCADA / DCS / cloud historian systems via Modbus, OPC-UA, and IEC 61850 — with sub-microsecond PTP time synchronization across the fabric.

Site Backbone — Falcon

Falcon 25G / 100G / 400G switches running Hardened SONiC scale from single-site deployments to multi-site backbones, with full L2/L3 (BGP, OSPF, IS-IS, VxLAN/EVPN, SR-MPLS) and unified Marvell CPSS SDK across the line.

OT-Grade Security & Manageability

SecureIQ multilayer in-network security, hardware-accelerated BFD, TACACS+/RADIUS, 802.1AE MACsec, and uCentral cloud management (TIP / OpenLAN certified) — built for continuous uptime in mission-critical process environments.
