Cisco QSFP-40/100-SRBD=

Overview

The Cisco QSFP-40/100-SRBD= is a high-speed transceiver module designed to provide up to 100 Gbps Ethernet connectivity using a compact QSFP+ form factor. It supports both 100 Gigabit and 40 Gigabit Ethernet standards, enabling network upgrades without the need for new cabling or additional rack space. This module is ideal for data centers and enterprise networks requiring reliable, high-bandwidth links over multimode fiber up to 100 meters.

Key features

• Dual-rate support for 100GBase-BiDi and 40GBase-BiDi Ethernet allows flexible bandwidth upgrades while maintaining existing infrastructure.
• Compatibility with Cisco Nexus 9348GC-FXP switches simplifies integration and reduces configuration complexity.
• Use of LC connectors and OM4 multimode fiber ensures consistent performance across fiber runs up to 100 meters.
• Compact QSFP+ design maximizes port density, helping to conserve valuable rack space in dense network environments.
• Low power consumption reduces operational costs, making it suitable for large-scale deployments where energy efficiency matters.
• Backed by a 90-day Cisco warranty, providing assurance for deployment in critical production networks.

Connectivity and compatibility

This transceiver module is designed to work seamlessly with Cisco Nexus 9348GC-FXP switches, enabling straightforward upgrades of existing network links. It uses LC duplex connectors compatible with standard OM4 multimode fiber, which is commonly deployed in data centers and enterprise environments. Supporting both 40G and 100G Ethernet standards over BiDi fiber means it can fit into a variety of network topologies without requiring new cabling infrastructure.

Ideal uses and environments

The module is well suited for data centers, enterprise core networks, and service provider points of presence where high-speed, short-reach connections are essential. It supports spine-to-leaf aggregation and east-west traffic within server farms, making it a strong choice for environments that demand high port density and efficient power usage. Network teams looking to upgrade bandwidth while preserving existing fiber infrastructure will find this transceiver particularly valuable.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
