4、rmation.4OSFP-D2P:Direct-To-Plug Liquid Cooling The integrated coldplate replaces the integrated heatsink,maintaining the same height as OSFP.The cold plate is assembled with a pair of blind-mate male mini-QDs.The host card is assembled with female mini-QDs connected to the coolant lines.Liquid conn

5、ections are located at the rear of the module.OSFP-D2P is longer than the standard air-cooled OSFP.The integrated coldplate extends over the electrical connector to mate with the liquid connector.Cage design includes an open rear section to allow QDs to protrude and blind-mate behind the cage.Mini-Q

6、Ds should allow sufficient float to compensate for potential misalignments during mating.This design can be implemented either as single variants or ganged configuration with a shared manifold.All liquid-cooled plugs must be connected in a parallel flow arrangement.Ciena Corporation 2025.All rights
