Secure transmission of 100 Gbit/s with LEONI’s active & passive QSFP28 assemblies

Active and passive QSFP28 (Quad Small Form-Factor Pluggable) or 100GBASE-CR10 solutions from LEONI are the secure and fast copper interconnections for 100 Gbit/s and 50 GHz+ transmissions in data centers. Being constructed with low-loss ParaLink copper cables, they are the ideal low-cost, low-power, low-latency and hot-pluggable alternative to fiber optic modules when connecting servers, routers, switches and storage systems.

LEONI QSFP28 DAC assemblies feature:

  • 100 Gbit/s (25 Gbit/s per channel) transmission over 16 ft/6 m (passive) and 49 ft/15 m (active)
  • AWG sizes of 24, 26, 28, 30 and 32
  • 50 GHz transmission and beyond
  • industry leading signal integrity with low NEXT, FEXT, insertion loss and jitter
  • superior mechanical performance with optimum flexure over small bending radii
  • optimized paddle card design for passive and active assemblies with repeater or retimer
  • conformance to SFF 8665, IEEE 802.3bj and InfiniBand EDR
  • low power consumption
  • certification according to UL13 CL2 in compliance with CSA FT4
  • customized solutions
