DAC/AOC/AEC Cables
200/400G DAC/AOC/AEC

200/400G DAC/AOC/AEC

Shop LINK-PP compatible 200G and 400G AOC / breakout cables for high-density spine/leaf and AI/HPC fabrics. This category groups MSA-aligned QSFP-DD and QSFP56 active optical assemblies—including 400G QSFP-DD to 2×200G QSFP56 and 200G QSFP56 to 2×100G QSFP56 breakouts—coded for Arista, NVIDIA/Mellanox, and generic platforms. Start from the parent DAC/AOC hub for lower-rate copper DACs, pair with 400G optics when you need pluggable modules, or open a Cisco compatible listing when matching an OEM PN. Confirm form factor on both ends, breakout map, and cable length on each product page before ordering.

Frequently asked questions

01.Which 200G/400G cable types does this store list?
This category focuses on LINK-PP 200G QSFP56 and 400G QSFP-DD active optical cables (AOC), including breakout AOCs such as 400G QSFP-DD to 2×200G QSFP56 and 200G QSFP56 to 2×100G QSFP56. Inventory is AOC-led today—check the parent DAC/AOC hub for copper DACs at other rates.
02.How do 400G QSFP-DD to 2×200G breakout AOCs work?
A 400G QSFP-DD to 2×200G QSFP56 breakout AOC presents one QSFP-DD end to the switch and two QSFP56 ends to downstream ports or NICs. Both the host and the far-end devices must support the breakout / dual-port mode. Confirm cage type (QSFP-DD vs OSFP), lane mapping, and length (for example 5 m) on the individual PDP.
03.Should I choose AOC, DAC, or AEC at 200G/400G?
At 200G/400G, passive DAC reach is short and platform-specific; many fabrics prefer AOC for row-scale flexibility or AEC/active copper where the OEM qualifies it. This store’s current listings emphasize AOC breakouts—use the PDP datasheet for power class, bend radius, and qualified length, and do not assume a 100G DAC length rule still applies.
04.Are these cables coded for Arista and NVIDIA/Mellanox?
Yes—pick the Compatible PN that matches your platform (for example Arista or Mellanox/NVIDIA-coded AOCs). LINK-PP assemblies are EEPROM-coded for host recognition. When you need pluggable 400G modules instead of fixed cables, browse 400G QSFP-DD / OSFP optics.
05.Can I use these AOCs in OSFP cages?
Only if the cable connector matches the host cage. QSFP-DD AOCs fit QSFP-DD ports; OSFP platforms need OSFP-ended assemblies. Do not force a QSFP-DD connector into an OSFP cage. Check the product title and datasheet for QSFP-DD vs QSFP56 vs OSFP ends before ordering.
