  • Intel® XL710-BM1 LAN controller
  • 4x 10GbE SFP+ ports
  • 2 pairs bypass segments
  • Based on OCP NIC 3.0 spec with extended depth and height of OCP NIC 3.0 SFF physical form factor
  • Available in two models: APTNC-OX4SS-BP (short range) and APTNC-OX4SL- BP (long range)

The Portwell APTNC series offers OCP (Open Compute Project) NIC 3.0 cards with network bypass function, an industry-leading design concept. Featuring a convenient thumbscrew pull-tab design to simplify maintenance and upgrades, the APTNC series NICs are also designed on a compact form factor, and yet are configured with high port density to optimize connectivity options. Furthermore, the APTNC series of network adapters helps ensure network connection and business continuity with its built-in network bypass function to optimize uptime, fail-safe network connectivity, as well as network security, resilience and threat prevention.

The APTNC-OX4S-BP network adapter series features Portwell’s innovative proprietary design based on OCP NIC 3.0 specification with extended depth and height of the OCP NIC 3.0 SFF physical form factor, to provide even higher port density as well as more application design flexibility. Built with 4x 10GbE SFP+ ports and network bypass function, it offers two versions including APTNC-OX4SS-BP with short-range SFP+ transceivers, and APTNC-OX4SL, long-range. APTNC-OX4S-BP network adapters are designed with Intel Ethernet controller, delivering energy efficiency, seamless interoperability, optimized load balancing, and enhanced agility through Data Plane Development Kit (DPDK) drivers.

Offering a comprehensive feature set to ensure superior performance and reliability, the APTNC-OX4S-BP bypass network adapter series is an ideal critical component for modern network infrastructure in diverse applications for next-generation firewalls, unified threat management (UTM) solutions, network routers, gateways, and software-defined wide-area networks (SD-WAN).
