Supermicro Kabel CBL-MCIO-1245M5RE MCIO x8 STR auf RE 30AWG - Kabel

Push PCIe Gen5 signals at up to 32 GT/s per lane through this 0.5 m MCIO x8 cable, engineered with 30 AWG conductors and straight-to-reverse-entry connectors for dense server and storage layouts.

Overview

The Supermicro CBL-MCIO-1245M5RE is a high-performance internal cable designed for PCIe Gen4 and Gen5 applications. It features an MCIO x8 straight connector on one end and an MCIO x8 reverse entry connector on the other, enabling flexible routing in tight spaces. With a length of 0.5 meters and 30 AWG wire gauge, it delivers excellent signal integrity and durability. The cable is foil and braid shielded to minimize electromagnetic interference, and its black high-temperature jacket ensures reliable operation in demanding server environments. It is fully compliant with RoHS standards and is ideal for connecting Supermicro motherboards, backplanes, and add-on cards with MCIO x8 ports.
