Active optical cables (AOCs) for 100 Gbit/s

AOCs (active optical cables) for QSFP28 interfaces

LEONI QSFP28 or 100GBASE-SR4 AOCs are the low-power, low-weight and hot-pluggable solution for 100 Gbit/s optic interconnections of servers, routers, switches and storage systems in data centers or high performance computing. They conform with the IEEE 802.3bm specification and support 100 Gbit/s Ethernet over up to 70 m (230 ft) with an OM3 or up to 100 m (328 ft) with an OM4 multimode fiber optic cable.


  • Supporting 100 Gbit/s (25 Gbit/s data rate per full-duplex channel)
  • Industry-leading signal integrity
  • Low power consumption <2.0 W
  • Superior electrical and mechanical performance
  • Link length up to 70 m (OM3) or up to 100 m (OM4)
  • Conforming to SFF-8665, SFF-8679, SFF-8636 and IEEE 802.3bm
  • BER better than 10-12
  • VCSEL and PIN Photodiode based optical engine with an optical wavelength of 850 nm
  • Channels are containing a retiming CDR
  • Auto CDR-Bypass at lower data rates to save power
  • Hot pluggable
  • 0°C to +70°C operating case temperature
  • RoHS compliance
  • UL certified cables (OFNR, OFNP)
