Transceptor CBO QSFP-40G-SR4 40Gbps módulo de fibra ótica

The Transceiver CBO QSFP-40G-SR4 40Gbps fiber optic module is a hot-pluggable QSFP form-factor transceiver designed for short-range multimode fiber links. It supports 40 Gigabit Ethernet over MMF using SR4 signaling and provides a compact, high-density solution for data center and switch-to-switch connectivity. The module is intended for use in environments where reliable 40G uplinks and low-latency, high-throughput connections are required.

Advantages

This QSFP-40G-SR4 module delivers 40 Gbps aggregate bandwidth in a single QSFP package, enabling high-density port deployment in racks and switches. The hot-pluggable design simplifies installation and maintenance without powering down equipment. Optimized for short-reach multimode fiber, the module reduces cabling complexity in data center topologies and supports common SR4-compatible transceiver ecosystems.

Suitable for

• 40 Gigabit Ethernet uplinks between switches and aggregation devices
• Short-range multimode fiber links in data center top-of-rack and spine-leaf architectures
• High-density blade servers and network appliances with QSFP ports
• Environments requiring hot-pluggable, low-latency 40G connectivity

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate
• Fiber type: Multimode fiber (MMF)
• Signaling: SR4 (short-range, 4-lane)
• Typical reach: designed for short-range multimode links (data center distances)
• Interface: MPO/MTP parallel fiber connection compatible with SR4 cabling
• Installation: hot-pluggable into QSFP ports

How to use

Insert the QSFP-40G-SR4 transceiver into an available QSFP port on a compatible switch or network device while the device is powered on. Connect the multimode MPO/MTP cable between transceivers or between a transceiver and a breakout harness as required by your topology. Ensure that the fiber type (MMF) and trunking (SR4-compatible MPO/MTP cabling) match the module specifications. Monitor link status through the device management interface to confirm a stable 40G connection.

Recommendations

For reliable performance, use OM3 or OM4 multimode fiber and SR4-compatible MPO/MTP cabling, maintain proper fiber cleanliness and bend radius, and verify switch compatibility with QSFP SR4 modules. Use appropriate breakout cables or cassette assemblies for connectivity to duplex interfaces if needed.
