QSFP-40G-SR4-S Description
QSFP-40G-SR4-S is a Cisco 40GBASE-SR4 S-Class QSFP+ transceiver module designed for high-density, low-power 40 Gigabit Ethernet connectivity. Also referred to as "Cisco 40GBASE-SR4 S-Class module" or "QSFP+ 40G SR4", this module supports up to 100 meters on OM3 and 150 meters on OM4/OM5 multimode fiber, utilizing an MPO-12 connector. It offers a cost-effective solution for data center, enterprise, and high-performance computing networks requiring reliable, short-reach 40G optical links. The S-Class version is optimized for Ethernet applications and does not support FCoE or 4x10G breakout. Fully compliant with IEEE 802.3ba 40GBASE-SR4 standards, the QSFP-40G-SR4-S ensures seamless interoperability and simplified deployment.

Key Features
- Target Application: Entry-level, cost-sensitive 40G Ethernet deployments in data centers and campus networks.
- Scenario: Used primarily for short-reach backbone or aggregation links between switches and routers within the same rack or adjacent racks.
- Functional Highlights:
- Optimized for standard 40GBASE-SR4 Ethernet links using OM3/OM4 multimode fiber.
- Does not support FCoE or 4x10G breakout, making it ideal for customers who only need basic high-speed Ethernet connectivity.
- Perfect for high-density environments where simple plug-and-play 40G connectivity is required.
- Typical Users: Enterprises and data centers focused on simple, low-cost 40G upgrades with no storage traffic.
Applications Scenarios
Enterprise Data Centers
High-bandwidth aggregation and core switching in leaf-spine architectures.
Cloud Computing & HPC
Short-reach 40G links between servers, switches, and storage within racks or across rows.
Service Providers
Metro Ethernet and campus backbone connections requiring scalable, cost-effective 40G links.

Installation & Usage Tips
- Connector Requirements:
Use only MPO-12 (female) connectors with PC or UPC end-face types for optimal performance. Patch cords with APC connectors are not supported. - Fiber Type:
Use laser-optimized OM3, OM4, or OM5 multimode fiber.- OM3: Up to 100 meters
- OM4/OM5: Up to 150 meters
- Proper Handling:
- The module is hot-swappable; it can be installed or removed while the system is powered on.
- Before insertion, clean the MPO connector end face to avoid signal loss.
- Avoid touching the optical interface to prevent contamination.
- Breakout Usage:
The S-Class (QSFP-40G-SR4-S) does not support 4x10G breakout mode. For breakout functionality, use QSFP-40G-SR4 or QSFP-40G-CSR4. - Installation Procedure:
- Ensure you are grounded using an ESD wrist strap.
- Align the module to the QSFP+ port and gently slide it in until it clicks into place.
- Connect the MPO patch cable securely.
- Check module LED and diagnostics for proper operation.
- Removal:
Pull the bail latch downwards to release the module, and gently slide it out.
