Fiber optic transceiver module BlueOptics S26361-F3986-E40 40000 Mbit/s QSFP 850 nm

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.

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.
