## Summary description

CBO QSFP-40G-LR4 is a QSFP+ fiber optic transceiver supporting 40G data rate with 1310 nm wavelength. Designed for long-reach single-mode links, it fits QSFP-compatible ports and provides high-bandwidth interconnects for switches, routers and servers. Suitable for data center uplinks and enterprise backbone connections, it offers straightforward plug-and-play installation.

## Long description

The CBO Transceiver QSFP-40G-LR4 Fiber Optic 40G 1310nm is a QSFP+ form factor optical module designed for 40 Gigabit Ethernet links over single-mode fiber. It operates at a center wavelength of 1310 nm and supports long-reach transmission suitable for uplinks between switches, routers and servers. Compatible with QSFP ports, the transceiver provides a compact, hot-pluggable solution for high-bandwidth interconnects in data center and enterprise network environments.
Advantages
This transceiver delivers 40 Gbit/s aggregated bandwidth with energy-efficient operation and a small QSFP package that simplifies port density management. The module supports long-reach single-mode fiber, enabling extended link distances without intermediate repeaters. Plug-and-play compatibility with standard QSFP ports reduces deployment time and minimizes configuration complexity.
Suitable for
Data center uplinks and spine-to-leaf interconnects
Enterprise backbone connections between distribution switches
High-bandwidth links for routers and aggregation switches
Server clusters requiring 40G optical connectivity
Key specifications
Form factor: QSFP+ (Quad Small Form-factor Pluggable Plus)
Data rate: 40 Gbit/s aggregated
Wavelength: 1310 nm
Fiber type: Single-mode fiber (SMF)
Reach: Designed for long-reach single-mode links (long distance)
Interface: Hot-pluggable QSFP electrical/optical interface
Application: 40 Gigabit Ethernet
How to use
Insert the QSFP+ transceiver into a compatible QSFP port on the switch, router or server until it seats securely. Connect single-mode fiber cables with appropriate LC connectors to the module's optical interface, ensuring correct transmit/receive polarity. After physical installation, allow the host device to recognize the transceiver; most systems enable automatic link negotiation and will detect the module as a 40G optical port. If required, verify link status and optical parameters using the host device management interface.
Usage recommendations
Use quality single-mode fiber with matching connectors and maintain proper cleanliness of optical end faces to ensure optimal performance. Verify compatibility with the host device's QSFP port and firmware requirements before deployment, and follow ESD precautions when handling the module.
