JMT ADT-R89M-F37C PCIe 4.0 x8 to x16 Extension Card 128Gbps MCIO External Chassis Supports 2U/4U Chassis (50CM)

JMT ADT-R89M-F37C PCIe 4.0 x8 to x16 Extension Card 128Gbps MCIO External Chassis Supports 2U/4U Chassis Product Model: R89M Product Name: PCIe 4.0 x8 to X16 (MCIO) Adapter Card Speed Bandwidth: PCIe 4.0 x8 Product Dimensions: All dimensions are maximum values R89M: Length 111.18mm × Height 121mm × Thickness 21.6mm Product Weight: R89M (including bracket) (50g) Finish Color: Black Operating Temperature: -40°C to 80°C Flame Retardant Rating: 94V0 Model Description R89M: PCIe 4.0 x8 to SFF-TA-1016 Adapter Card, Gen4 x8 Bandwidth R89M-F37C: PCIe 4.0 x8 to x16 Extension Cable (1-to-1), Gen4 x8 Bandwidth Product Advantages: 1. Supports PCIe 4.0 x8, compatible with Gen3/Gen4 2. Includes full-height and half-height backplates for versatile deployment environments 3. High-frequency, low-resistance, high-temperature resistant, anti-oxidation PCB material. Maintains shape with yellow crystal translucency—no whitening or darkening. Can the R89M be split into two x4 channel? Yes, but requires motherboard support for x4x4x4x4 splitting. When connected to an MCIO splitter cable, the x8 channel can be divided into two x4 channels. Both channels retain Gen4 performance after splitting.
