Transceptor CBO QSFP-40G-SR4 fibra ótica 40Gbps 850nm

The Transceiver CBO QSFP-40G-SR4 Fiber Optic 40Gbps 850nm is a quad small form-factor pluggable (QSFP) module designed for short-range 40 Gigabit Ethernet links over multimode fiber. Operating at an 850 nm wavelength, this BlueOptics transceiver supports a 40 Gbps aggregate data rate and integrates into compatible switches, routers and server network interfaces to enable high-density data center interconnects and server-to-switch connections.

Advantages

The compact QSFP form factor allows for high port density and hot-pluggable installation without powering down equipment. Using multimode fiber and an 850 nm optical interface, the module provides cost-effective short-reach connectivity with low latency and stable signal performance. Compatibility with standard QSFP sockets simplifies upgrades of existing 40GbE infrastructure and reduces cabling complexity by aggregating four lanes into a single transceiver.

Suitable for

• Short-range 40 Gigabit Ethernet links within data centers
• Server-to-switch and switch-to-switch interconnects
• High-density aggregation switches and spine/leaf architectures
• Upgrading or expanding existing 40GbE multimode networks

Key specifications

• Form factor: QSFP (quad SFP)
• Data rate: 40 Gbps aggregate
• Wavelength: 850 nm
• Fiber type: Multimode fiber (MMF)
• Range class: Short-range (SR) suitable for short-reach links
• Interface: MPO/MTP or compatible multimode fiber connector (depending on system cabling)
• Hot-pluggable: Yes

How to use

Install the transceiver into a compatible QSFP slot on a switch, router or network interface card until it clicks into place. Connect the multimode fiber cable using the appropriate MPO/MTP connector to the transceiver port and ensure correct fiber polarity. Once installed, verify link status and speed through the host device management interface. For removal, power down the link if required by the host device documentation and gently pull the module out using the release latch.

Recommendations

Use high-quality multimode fiber and follow the switch or server vendor's compatibility list to ensure proper operation. Keep optical connectors clean and capped when not in use, and avoid bending fiber beyond recommended radii. For maximum performance, match transceiver and cabling types (e.g., OM3/OM4) to the intended link distance and monitor link status after installation.
