Frequently Asked Questions
What is the primary function of the HPE 882251-B21 QSFP28 transceiver? +
The HPE 882251-B21 is a high-performance QSFP28 transceiver designed to facilitate 100GbE connectivity. It serves as a critical interface for data center switches and servers, converting electrical signals into optical signals to enable high-speed, long-distance data transmission over fiber optic cabling within enterprise network architectures.
Which physical interface type does the 882251-B21 module utilize? +
This module utilizes a standard QSFP28 form factor, which is optimized for 100G data rates. It is engineered to plug directly into the QSFP28 port of compatible HPE networking hardware, ensuring a streamlined installation process while maintaining the density requirements needed for modern high-bandwidth server and switch deployments.
Is the HPE 882251-B21 compatible with existing HPE server and switch portfolios? +
Yes, this transceiver is specifically validated for use with HPE networking equipment. By utilizing genuine HPE-certified transceivers, you ensure seamless interoperability and prevent potential performance bottlenecks or system errors that can occur when using non-branded or incompatible third-party optics within a proprietary HPE ecosystem.
What are the common deployment scenarios for this 100G QSFP28 module? +
The 882251-B21 is ideal for high-density core switching and data center aggregation layers. It is frequently deployed to connect leaf switches to spine switches in spine-leaf network topologies or to provide high-speed uplinks for server clusters requiring 100GbE bandwidth to handle virtualization, cloud workloads, and large-scale data storage traffic.
Does the 882251-B21 support hot-swapping during network operations? +
Like most standard QSFP28 modules, this unit supports hot-swapping functionality. This allows network administrators to install or remove the transceiver from an active switch or server port without the need to power down the host device, effectively minimizing network downtime and facilitating rapid maintenance or hardware expansion tasks.
How does the QSFP28 standard impact overall data center power consumption? +
The QSFP28 form factor is significantly more power-efficient compared to older high-speed interface standards like CXP or CFP. By utilizing this module, enterprises can increase their port density and overall throughput per rack while keeping power consumption and heat dissipation within manageable limits, which is vital for large-scale data center thermal management.
What performance benefits does the 882251-B21 offer over 40G QSFP+ modules? +
The 882251-B21 provides a substantial performance upgrade by offering 100Gbps of bandwidth, which is 2.5 times faster than traditional 40G QSFP+ modules. This increased capacity reduces latency and eliminates traffic congestion in bandwidth-intensive environments, making it an essential component for modernizing aging infrastructure to meet the demands of enterprise-level applications.
Are there specific fiber cabling requirements for this QSFP28 transceiver? +
This transceiver is designed to operate over high-quality fiber optic cabling. You must ensure that your cable plant—whether single-mode or multi-mode depending on the specific optical reach specifications—is clean and properly terminated to maintain signal integrity at 100G speeds, as even minor contaminants can degrade performance or trigger link errors.
Can I request a bulk quote for the HPE 882251-B21 through BuyRouterSwitch.com? +
