## Summary description

The BlueOptics S26361-F3986-E40 is a fiber optic transceiver module designed for high-speed data transfer at 40000 Mbit/s. It features a QSFP interface and operates at a wavelength of 850 nm, making it suitable for short-range communication in data centers and enterprise networks.

## Long description

The BlueOptics S26361-F3986-E40 is a fiber optic transceiver module engineered for 40 Gbit/s connectivity in short-range links. With a QSFP interface and 850 nm wavelength operation, this module is intended for use in data centers, server rooms and enterprise network aggregation where multimode fiber links are used. The compact QSFP form factor provides a high-density option for switches and servers that require reliable 40 Gbit/s uplinks or interconnects.
Advantages
This transceiver supports a maximum data transfer rate of 40000 Mbit/s over multimode fiber at 850 nm, enabling high-throughput connections with low latency. The QSFP interface allows hot-pluggable installation into compatible switch and router ports, simplifying upgrades and replacements. The module's design focuses on interoperability with standard QSFP ports and on supporting short-range, high-density deployments common in modern network environments.
Suitable for
 40 Gbit/s short-reach links in data centers
 Server-to-switch and switch-to-switch aggregation
 High-density rack installations requiring QSFP ports
 Enterprise backbone and campus network uplinks over multimode fiber
Key specifications
 Interface type: QSFP (Quad Small Form-factor Pluggable)
 Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
 Operating wavelength: 850 nm for multimode fiber
 Typical application: short-range multimode fiber links
 Form factor: QSFP hot-pluggable module for high-density ports
How to use
Install the BlueOptics QSFP transceiver into a compatible QSFP port on a switch, router or server according to the host device manual, ensuring the module is inserted until the latch secures it. Connect multimode fiber patch cords with the appropriate MPO/MTP or duplex multimode connectors as required by the system. Verify link status and operational parameters via the network device management interface and monitor for proper signal levels. For best results, follow the fiber manufacturer's cleaning and handling procedures and confirm that the host device supports 40 Gbit/s QSFP modules.
Usage recommendations
Use multimode fiber compliant with the module's wavelength for short-range links, maintain clean fiber endfaces, and verify compatibility with the host equipment's QSFP port and firmware. Replace transceivers following static-sensitive handling procedures and consult the switch or router documentation for any required configuration steps to enable 40 Gbit/s operation.
