Description

This verified reference design is a signal conditioning solution for front-port QSFP+ supporting two 40GbE ports compatible with 40G-CR4/SR4/LR4 and 10G SFF-8431 requirements. The design is applicable to optical and passive/active copper cables. It allows for reach extension between the Switch ASIC and the front-port QSFP+ which is often required for the outermost ports of a Top-of-Rack (ToR) switch or for add-in mezzanine implementations of QSFP+ line cards.

Features
  • Front-port stacked QSFP+ implementation with signal conditioning to support 40GbE/10GbE optical and passive copper
  • Extends reach between Switch and front-port by up to 3x beyond nPPI/SFF-8431 host channel loss limit
  • Low-power/low-cost solution for front-port signal conditioning
  • Applicable to Top-of-Rack (ToR) switch and line card systems
  • Single power supply, no firmware required, no heatsink required, no reference clock required
  • Lab-tested HW example including 40GbE/10GbE-specific test data
