Product Description
The HPE P49764-B21 transceiver delivers 1x400GbE connectivity specifically for InfiniBand NDR environments. It is designed to connect on the host channel adapter (HCA) side, using an OSFP form factor to ensure proper fit and integration within supporting HPE network equipment. This transceiver uses multi-mode fiber optic technology, supporting transmission distances up to 50 meters, making it suitable for short-reach data center interconnects. Typical users include data center operators and IT professionals managing high-speed InfiniBand fabrics requiring 400GbE bandwidth for compute and storage networking. Key Features 1x400GbE data rate tailored for InfiniBand NDR networks OSFP form factor compatible with HCA-side ports Multi-mode fiber support enabling 50-meter link length Designed and manufactured by HPE (P/N P49764-B21) Optimized for short distance high-throughput interconnects This transceiver plays a crucial role in enabling high-bandwidth, low-latency connections within server and storage clusters. Its compliance with InfiniBand NDR specifications and multi-mode fiber provides a balance between speed and deployment flexibility in data center environments.

Use Cases
This transceiver is typically deployed in data center environments where InfiniBand NDR fabrics require 400GbE bandwidth for server-to-server or server-to-storage communication. It benefits environments focused on high throughput and low-latency networking within confined physical distances. How It's Used: Connecting HPE HCA ports in InfiniBand NDR high-speed fabrics Short-range interconnects within data center racks or between adjacent racks Facilitating 400GbE data transfer in multi-mode fiber optic networks Supporting clustered server environments requiring high bandwidth Integrating into HPE networking modules compatible with OSFP transceivers The transceiver supports the operational demands of modern data centers by providing a reliable interface for high-speed data transmission. Its multi-mode fiber compatibility and 50-meter reach address common cabling distances within rack or row level setups.

FAQ's
What type of connector does the P49764-B21 use? The P49764-B21 utilizes an OSFP form factor designed for HCA-side connections in InfiniBand NDR networks. This ensures compatibility with OSFP ports on supported HPE host channel adapters. What fiber type is supported by this transceiver? This transceiver supports multi-mode fiber, enabling data transmission over shorter distances within data centers typically limited to 50 meters. What is the maximum transmission distance of the P49764-B21? The device supports transmission distances of up to 50 meters over multi-mode fiber, suitable for intra-rack or inter-rack connections in data centers. Which data rate does the HPE P49764-B21 support? It supports a 1x400GbE data rate compatible with InfiniBand NDR networks, enabling high-bandwidth data transfers. Is the P49764-B21 compatible with single-mode fiber? This transceiver is designed exclusively for multi-mode fiber and does not support single-mode fiber optic connections. Can the P49764-B21 be used on the switch side? This transceiver is specified for HCA-side installation and is intended for host channel adapter ports rather than switch-side connections.
