Secure transmission of 25 Gbit/s with LEONI’s active & passive SFP28 assemblies

Active and passive SFP28 (Small Form-Factor Pluggable) or 25GBASE-CR4 solutions from LEONI are the secure and fast copper interconnections for 25 Gbit/s  transmissions in data centers. Being constructed with low-loss ParaLink copper cables, they minimize cost, power and latency when connecting servers, routers, switches and storage systems.

LEONI SFP28 DAC assemblies feature:

  • 25 Gbit/s 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 8402, IEEE 802.3bj and InfiniBand
  • low power consumption
  • certification according to UL13 CL2 in compliance with CSA FT4
  • customized solutions
