Multi-Vendor MSA Compatible 400G DAC Cable 400G-PDAC-QSFP-DD Datasheet

HPE Compatible R8M46A Module is based on our product 400G-PDAC-QSFP-DD. When You will order it will be encoded to be compatible with HPE equipment and it will be labeled with part number: 400G-PDAC-QSFP-DD-2-HP, where HP means HPE Compatible. Above You can download data-sheet of our 400G-PDAC-QSFP-DD product.

# Product Description

Our Compatible HPE Aruba R8M46A HPE 400GbE QSFP-DD to QSFP-DD 2m Direct Attach Copper Cable is based on our 400G-PDAC-QSFP-DD-2 product, which has the same parameters and is manufactured in accordance with the same industry standards as its OEM counterpart. HPE compatible 400GbE QSFP-DD to QSFP-DD 2m Direct Attach Copper Cable is equipped with MSA standard QSFP-DD compatible transceiver assembly at each end of cable and uses Copper Twinax Cable in between the assembly unit. This cable is designed for operation in standard temperature networking environments ranging from 0°-70°C. As passive 400G DAC do not support any electrical transmission signal boosting on regeneration, length of 400G DAC is limited up to 3 meters, which is enough to support 400G connections within same or neighboring equipment racks. 400G DAC supports 8 separate fully duplex copper data lanes, capable of 28 Gbps NRZ or 56 Gbps PAM4 with aggregated thoughput 212.5-425 Gbps and such applications as 400G Ethernet (412.5Gbps), 200G Ethernet (206.25Gbps), InfiniBand EDR (100Gbps), InfiniBand HDR (200Gbps) . Most popular applica-tions of 400G DAC are cost effective close range interconnections within equipment room of telecom operators or data centers, intercon-necting LAN applications with speeds up to 400G.

Our Compatible HPE Aruba R8M46A Cable is CE/RoHS certified, it meets product safety standards, and is compliant with QS-FP-DD Multi Source Agreement (MSA) and IEEE 802.3bs and IEEE 802.3by specification. To ensure smooth operation, we have completed compatibility tests for this cable with the most recent platforms of HPE Aruba networking equipment, allowing us to encode cable EEPROM memory to be compatible with and work seamlessly in HPE Aruba platforms. We are committed to quality, therefore before delivering our products, we conduct stringent quality inspections that include optical parameter measurements, connector cleanliness tests, and EEPROM memory data validation tests. If you have any questions, please Contact us. We will gladly learn about your needs and recommend the best compatible products from our portfolio.
