Cisco QSFP-40G-SR-BD: Efficient 40Gbps BiDi Transceiver for Data
Centers
The Cisco QSFP-40G-SR-BD BiDi Transceiver is a cutting-edge 40 Gigabit Ethernet QSFP+ module designed for high-density data center and enterprise applications. Its unique Bi-Directional (BiDi) technology allows 40Gbps transmission over just two strands of
multimode fiber, significantly reducing cabling complexity and
costs. This makes it an ideal solution for upgrading existing
10Gbps infrastructure to 40Gbps without extensive fiber re-cabling,
often connecting directly into Cisco Network Switch platforms.
Optimized Fiber Utilization
A key advantage of the QSFP-40G-SR-BD is its ability to achieve
40Gbps over existing duplex multimode fiber infrastructure (e.g.,
OM3/OM4). This eliminates the need for expensive and complex MPO/MTP cabling
upgrades, maximizing the efficiency of your current fiber plant.
High Performance for Data Center Links
This transceiver provides robust 40 Gigabit Ethernet connectivity
for short-reach applications, typically up to 100 meters over OM3
fiber and 150 meters over OM4 fiber. It ensures high bandwidth and low latency for critical data center
interconnects and aggregation layers.
Seamless Integration and Hot-Swappable
As a QSFP+ form factor, the module is hot-swappable, allowing for
quick and non-disruptive upgrades or replacements. It seamlessly integrates into compatible Cisco networking
equipment, ensuring straightforward deployment and reliable
operation.
Enhancing Network Aggregation
The QSFP-40G-SR-BD is vital for building efficient and scalable
data center fabrics. It provides the high-speed optical links
necessary for connecting core Cisco Network Switch devices and aggregation layers, indirectly supporting the
high-bandwidth demands that can arise from dense Cisco Wireless AP deployments.
