Network Interconnects — DAC, AOC, Transceivers & Cables for Every Network Speed
Network interconnects are the physical links that tie your infrastructure together — connecting switches to servers, switches to switches, and servers to storage. At Resilient Tec, our interconnect catalog covers every major form factor and speed from 1G SFP to 800G OSFP, all pre-programmed with the EEPROM data your platform expects for plug-and-play installation.
Whether you need a passive DAC for an in-rack server connection, an active optical cable for a cross-rack run, or a compatible transceiver for a long-distance uplink, you'll find it here — compatible with Mellanox/NVIDIA, Cisco, Arista, Juniper, Dell, HP, and more.
What Type of Interconnect Do You Need?
| Product Type | Best For | Reach | Power |
|---|---|---|---|
| Passive DAC Cable | In-rack server/switch connections | Up to 5M | 0W |
| Active DAC Cable | Slightly longer in-rack runs | Up to 15M | Very low |
| AOC Cable | Cross-rack, inter-row runs | Up to 100M | Low |
| SR Transceiver | Short-range fiber (300M–500M) | 300M–500M | Low |
| LR Transceiver | Long-range fiber (campus, WAN) | Up to 10km | Low–moderate |
| Breakout Cable | Fan one port to multiple endpoints | Up to 5M | 0W–low |
