Multi-Vendor MSA Compatible 400G-QSFP-DD-100 Datasheet

HPE Compatible R9J29A Module is based on our product 400G-QSFP-DD-100. When You will order it will be encoded to be compatible with HPE equipment and it will be labeled with part number: 400G-QSFP-DD-100-HP, where HP means HPE Compatible. Above You can download data-sheet of our 400G-QSFP-DD-100 product.

# Product Description

Our Compatible HPE R9J29A QSFP-DD transceiver is based on our 400G-QSFP-DD-100 product, which has the same parameters and is manufactured in accordance with the same industry standards as its OEM counterpart. Our HPE compatible X1E0 400G QSFP-DD SR8 MM850 100m OM4 MPO16/APC Transceiver version is designed for operation over a Double Fiber Multi-Mode Fiber (MMF) optical cable. It has a minimum guaranteed optical budget of 1.9 dB, which typically is enough to reach about 100m over OM5. However, distance is only an indicative parameter calculated for identification comfort. Finally, we calculate distance while keeping in mind the minimum (guaranteed) optical budget and the average attenuation of optical cabling in the industry. Our HPE R9J29A compatible transceiver uses a high-quality VSCEL Laser transmitter operating at 850 nm nominal wavelength and a 850 nm PIN Photodiode receiver. This module supports DDM/DOM optical diagnostics and provides diagnostic data about the current operating conditions. This compatible module has a MTP/MPO-16 connector and module is designed for operation in standard temperature networking environments ranging from 0°-70°C. The transceiver chipset supports data rates ranging from 425 Gbps and such applications as 400G Ethernet (412.5Gbps). It is important to note that the mentioned application support will vary depending on the port where the module will be used, and it supported applications as well as module speed configuration during ordering process, but we can ensure that our module will support at least the same functionality as its OEM counterpart. This is a multi-purpose transceiver that can be used in a variety of different places in today’s networking. As a result, Internet Service Provider (ISP) Aggregation and Backbone, Mobile Operator Core Networks and Data Center Core Network interconnections are the most popular applications for this product.

Our compatible HPE R9J29A X1E0 400G QSFP-DD SR8 MM850 100m OM4 MPO16/APC Transceiver is CE/RoHS certified, it meets product safety standards, and is compliant with QSFP-DD Multi Source Agreement (MSA) QSFP-DD MSA industry standard. To ensure smooth operation, we have completed compatibility tests for this module with the most recent platforms of HPE networking equipment, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly in HPE 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.
