AOC (Active Optical Cable)

AOC (Active Optical Cable) assemblies integrate VCSEL-based transceivers at both ends of a multimode fiber pair — delivering cross-rack and end-of-row reach (typically 30–100 m) at half the weight and a third of the bend radius of patch-cord + transceiver setups. Above 5 m, AOC is usually lower-cost than separate transceivers and assemblies. Optiunik manufactures AOCs across 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G QSFP56, 400G QSFP-DD, and 800G OSFP form factors, in standard lengths from 3 m to 30 m and custom lengths to 100 m. Breakout variants (1× QSFP28-to-4× SFP28, 1× QSFP-DD-to-4× SFP28, 1× OSFP-to-8× SFP28) ship in 1, 3, 5, and 10 m. Each cable is BER-tested end-to-end and programmed with customer switch coding.
