Netwerk-transceivermodule CBO 49Y7884-BO copper QSFP 40000 Mbit/s

CBO 49Y7884-BO is a BlueOptics copper QSFP network transceiver module that supports a 40000 Mbit/s data rate. The module is designed for installation in QSFP ports of high-density switches and servers to provide 40 Gbps copper connectivity for short-reach links and equipment interconnects. It is suitable for environments where a copper QSFP interface is required for aggregation, uplinks or direct switch-to-switch connections and where fiber is not used.

Advantages

The copper QSFP transceiver offers a compact form factor compatible with standard QSFP ports, enabling high-density deployment in racks and chassis. It provides a stable 40 Gbps electrical connection over copper cabling for short distances, reducing the need for optical modules and simplifying cabling management in certain rack-level and top-of-rack scenarios. The module is designed for straightforward hot-pluggable replacement and integration with existing network hardware that supports QSFP copper interfaces.

Suitable for

• Data center uplinks and aggregation links
• Switch-to-switch direct connections within racks or adjacent racks
• High-density switch and server installations with QSFP ports
• Short-reach interconnects where copper cabling is preferred or required

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40000 Mbit/s (40 Gbps)
• Media type: copper cabling
• Application range: short-reach links and equipment interconnects
• Compatibility: designed for installation in QSFP ports of switches and servers

How to use

Install the module into a compatible QSFP port on the switch or server until it clicks into place, following the host device manufacturer’s instructions for hot-pluggable transceivers. Connect an appropriate copper QSFP cable between devices, ensuring cable type and pinout match the equipment requirements. Verify link status and data rate in the network device management interface and monitor for proper operation. Remove the module by releasing any retention mechanism and pulling it straight out to avoid damaging the port.

Recommendations

Use short, high-quality copper QSFP cables rated for 40 Gbps to achieve reliable short-reach connections. Verify that the network devices support copper QSFP modules and the specified data rate, and observe electrostatic discharge (ESD) precautions during handling. For longer distances or where optical isolation is needed, consider using appropriate fiber-based QSFP modules instead.
