Transceptor CBO QSFP-40G-SR4 40G 850nm módulo de fibra óptica

CBO Transceiver QSFP-40G-SR4 40G 850nm Fiber Optic Module is a hot-pluggable QSFP form-factor transceiver designed for short-range multimode fiber links at 850 nm. Intended for 40 Gigabit Ethernet environments, the module enables aggregation and high-density connectivity in data center topologies such as switch-to-switch links, server uplinks and spine-leaf architectures. The module supports standard QSFP interoperability and is optimized for multimode cabling infrastructures.

Advantages

The transceiver provides a compact QSFP footprint that consolidates four lanes into a single 40G interface, reducing port density and cabling complexity. Hot-pluggable design allows installation or replacement without powering down equipment. Operating at 850 nm, it is tuned for short-range multimode fiber with stable optical performance suitable for typical data center distances. Compliance with common QSFP specifications ensures compatibility with a broad range of switches and network devices.

Suitable for

• 40 Gigabit Ethernet switch-to-switch connections over multimode fiber
• Server uplinks and aggregation ports in data centers
• Spine-leaf network topologies requiring short-range high-bandwidth links
• High-density patch panels and QSFP-enabled line cards

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbit/s aggregate
• Operating wavelength: 850 nm
• Fiber type: Multimode fiber (MMF)
• Range: Designed for short-reach multimode links (data center distances)
• Connector interface: Compatible with MPO/MTP-style multimode connectors
• Installation: Hot-pluggable

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or network card until it clicks into place. Connect the multimode fiber assembly with the matching MPO/MTP connector, ensuring proper polarity and fiber type. The module is intended for short-range links; choose appropriate multimode patch cords and trunking for the target distance. After physical installation, verify link status and speed through the network device management interface and monitor optical levels where available.

Recommendations

Use OM3 or OM4 multimode fiber for optimal reach and performance at 850 nm, and ensure clean connectors to maintain signal integrity. Confirm device compatibility with QSFP interfaces and, where applicable, check switch vendor guidelines for third-party transceiver support. Replace or reseat the module only when necessary and observe ESD precautions during handling.
