Next-generation 10 GBaud module based on emerging SFP+ with host-based EDC [Topics in Optical Communications]

There has been an ongoing trend to require transceivers for use in datacom and telecom switches to be small and have low power dissipation to enable large port count switches. At speeds between 1 and 4 GBaud the SFP form factor is by far the most commonly used. Up to now 10 GBaud transceivers have used larger devices with larger power dissipations. This article describes the SFP+ module being specified by the SFF Committee (SFF 8431) that will enable the same port densities as the SFP module. The adaptive equalizers and high-speed transmission channels required in the switches to make the SFP+ module work successfully are also described
