Transceiver BlueOptics QSFP-200G-SR4-AL 200G SR4 850nm multimode

BlueOptics QSFP-200G-SR4-AL is a 200G SR4 multimode fiber transceiver that operates at an 850 nm wavelength. The module implements the QSFP form factor and is intended for short-reach, high-bandwidth links in data center and aggregation environments. It provides four parallel lanes to achieve an aggregate 200 Gbps throughput over multimode fiber, supporting low-latency, high-throughput interconnects between switches, routers and server racks.

Advantages

This transceiver delivers high-density 200 Gbps connectivity in a compact QSFP package, enabling efficient use of optical ports in equipment designed for short-range multimode links. Its multimode 850 nm optics are optimized for common data center multimode fiber types, offering predictable signal performance for typical short-reach distances. The module supports hot-pluggable installation and interoperates with network devices that accept QSFP SR4 modules, helping to simplify upgrades and maintain uptime during replacement.

Suitable for

• Data center spine-to-leaf and rack-to-rack connections
• High-throughput aggregation and top-of-rack switching
• Short-range fiber links within campus or enterprise LAN closets
• Low-latency interconnects for storage and compute clusters

Key specifications

• Optical wavelength: 850 nm
• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Transmission type: SR4, multimode parallel optics
• Aggregate data rate: 200 Gbps (four parallel lanes)
• Typical reach: short-range multimode links (designed for data center distances)
• Connector type: MPO/MTP-style parallel fiber interface
• Hot-pluggable capability for in-service replacement

How to use

Insert the QSFP-200G-SR4-AL transceiver into a compatible QSFP port on a switch or router while the host device is powered on or off, observing standard electrostatic discharge precautions. Connect the multimode MPO/MTP patch cable to the module’s parallel fiber interface, ensuring proper fiber polarity and that the cable is rated for 850 nm multimode operation. After insertion and cable connection, verify link status and speed through the host device management interface and monitor optical diagnostic parameters if available.

Usage recommendations

Choose OM3 or OM4 multimode fiber for reliable reach at 850 nm and maintain clean MPO/MTP connectors to minimise insertion loss. Confirm compatibility with the host equipment’s supported QSFP SR4 modules and verify fiber polarity and patching plans before deployment to ensure optimal 200 Gbps performance.
