## Long description

CBO BlueOptics FG-TRAN-QSFP+SR-BO is a QSFP+ short-range network transceiver module that supports a 40 Gbit/s aggregate data rate using an 850 nm wavelength. Intended for deployment in data centers and enterprise networks, the module provides quad-lane optical connectivity over multimode fiber for high-density switch uplinks, server interconnects and short-distance backbone links. The compact QSFP+ form factor enables straightforward insertion into compatible QSFP+ ports and supports common multimode fiber types for short-reach applications.
Advantages
The transceiver combines a 40 Gbit/s throughput with an 850 nm multimode optical interface in a QSFP+ package to deliver compact, high-density connectivity. It is designed for compatibility with standard QSFP+ ports and offers a plug-and-play installation model that reduces deployment time. Its short-range multimode design minimizes signal dispersion over distances typical for server racks and top-of-rack switch connections, helping to maintain reliable link performance in dense network environments.
Suitable for
40 Gbit/s switch-to-switch uplinks in data centers
Server-to-switch interconnects within the same rack or adjacent racks
Short-distance backbone links and aggregation layers over multimode fiber
High-density patch panels and QSFP+ port consolidation
Key specifications
Data rate: 40 Gbit/s aggregate (quad-lane)
Wavelength: 850 nm
Form factor: QSFP+ (quad small form-factor pluggable)
Optical interface: multimode fiber (short-reach)
Typical reach: designed for short-range links within data centers and enterprise sites
Connector type: duplex multimode fiber compatible via MPO/MTP breakout
How to use
Install the module by inserting the QSFP+ transceiver into a compatible QSFP+ port on a switch or server adapter until it seats securely. Connect the multimode fiber cable or MPO/MTP breakout assembly according to the switch vendor’s port labeling and fiber polarity guidelines. After connection, verify link status through the host device management interface and confirm the port negotiates at 40 Gbit/s. If required, follow device-specific procedures to enable or monitor the port, and ensure proper cable routing and strain relief to protect the transceiver interface.
Usage recommendations
The module is intended for short-reach multimode fiber environments. Use suitable OM3/OM4 multimode fiber and quality MPO/MTP connectors for reliable 40 Gbit/s links. Observe ESD precautions during handling and ensure compatible QSFP+ ports and firmware support on host devices for optimal interoperability.
