Transceptor CBO QSFP-40G-SR4 fibra óptica 40Gbps Short Range

The Transceiver CBO QSFP-40G-SR4 Fiber Optic 40Gbps Short Range is a quad‑lane QSFP module designed to support 40 Gbps short‑range links over multimode fiber. Intended for data center and high‑speed networking environments, this BlueOptics module provides multi‑lane 40G connectivity for intra‑rack and short‑distance links, enabling high throughput and low latency connections between switches, routers and servers with 40G SR interfaces.

Advantages

This QSFP-40G-SR4 transceiver delivers high aggregate bandwidth by combining four parallel lanes to carry a total of 40 Gbps. The form factor offers hot‑plug capability and compact QSFP dimensions for dense port deployments. Optimized for short‑range multimode fiber links, the module reduces latency and supports high‑speed aggregation while maintaining compatibility with standard QSFP cages and optical connectors.

Suitable for

• Intra‑rack switch-to-switch connections in data centers
• Server uplinks requiring 40 Gbps short‑range optical links
• Aggregation links within high‑density networking racks
• Low‑latency connections for high‑performance computing clusters

Key specifications

• Data rate: 40 Gbps aggregate (4 parallel lanes)
• Optical interface: QSFP multimode fiber
• Range: short‑range operation over multimode fiber (designed for intra‑rack and short distance)
• Wavelength: parallel multimode transceiver wavelengths per lane (designed for SR applications)
• Form factor: QSFP (compact, hot‑pluggable)
• Typical applications: data center 40G SR links, server uplinks, switch interconnects

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or server following the equipment manufacturer's guidance. Connect the multimode fiber cable with the appropriate MPO/MTP connector to the module's optical interface, ensuring correct polarity and secure connection. Verify link status and negotiate the expected 40 Gbps SR mode in the host device's network configuration. Follow standard electrostatic discharge (ESD) precautions during handling and avoid touching the optical interfaces to prevent contamination.

Recommendations

For reliable performance, use certified multimode fiber cables and MPO/MTP connectors rated for 40G SR operation, keep connector endfaces clean, and confirm that the connected equipment supports QSFP 40G SR links. Maintain recommended fiber bend radii and inspect link diagnostics in the host device to monitor optical power and signal integrity.
