Network transceiver module CBO SRX-QSFP-40G-SR4 40 Gbit/s 850 nm QSFP+

CBO SRX-QSFP-40G-SR4 is a 40 Gbit/s QSFP+ network transceiver module that uses 850 nm optics for short-reach multimode fiber connections. The module is designed for data center and enterprise networking environments where high-density aggregation and uplink links between switches and servers are required. Its QSFP form factor integrates four 10 Gbit/s lanes in a single compact module to provide high throughput with simplified port management and installation.

Advantages

The module supports 40 Gbit/s aggregate bandwidth across four lanes, enabling efficient consolidation of multiple 10 Gbit/s links into a single QSFP+ port. Operating at 850 nm, it is compatible with standard multimode fiber types used in short-reach topologies. The compact QSFP+ design reduces space in high-density racks and simplifies cabling and port utilization. The transceiver provides reliable optical performance suitable for regular data center traffic patterns while facilitating easy hot-swap replacement and straightforward integration into existing network infrastructure.

Key specifications

How to use

Insert the QSFP+ transceiver into a compatible QSFP+ port on a switch or server line card, ensuring proper orientation and a secure mechanical latch. Connect an appropriate MPO/MTP multimode fiber cable between the transceiver and the remote device. Verify link status through the host device management interface and confirm lane configuration and speed settings if required. For hot-swap operations, follow the host equipment vendor's procedures to avoid traffic disruption.

Recommendations

Use OM3 or OM4 multimode fiber for optimal short-reach performance and maintain clean fiber connectors to ensure signal integrity. Verify compatibility with the host equipment vendor's supported transceiver list and observe manufacturer guidance on operating temperature and electrostatic discharge precautions during handling and installation.
