QSFP-transceivermodule BlueOptics QSFP-4X10G-LR-S 40000 Mbit/s 1310 nm

The BlueOptics QSFP-4X10G-LR-S is a QSFP fiber optic transceiver module engineered for aggregated 40 Gbit/s connectivity over single-mode fiber. Operating at a wavelength of 1310 nm, this compact module supports four 10 Gbit/s lanes in a single QSFP form factor and is intended for use in switches, routers and other network equipment with QSFP ports. With a lightweight design of approximately 40 g, the module provides a space- and power-efficient solution for high-density optical links.

Advantages

The module offers multi-lane aggregation in a single QSFP package, enabling 40 Gbit/s throughput while maintaining compatibility with equipment that accepts QSFP transceivers. Its operation at 1310 nm is suitable for medium- to long-reach single-mode fiber links. The compact, standardized QSFP form factor simplifies installation and replacement, and the low weight supports dense port deployments without adding significant mechanical load.

Suitable for

• 40 Gbit/s uplinks between switches and core devices
• Aggregation of four 10 Gbit/s channels in data centers
• High-density optical port deployments in enterprise networks
• Single-mode fiber connections requiring 1310 nm wavelength

Key specifications

• Interface type: QSFP form factor, four 10 Gbit/s lanes
• Maximum data transfer rate: 40000 Mbit/s aggregate
• Operating wavelength: 1310 nm
• Suitable fiber type: single-mode fiber

How to use

Ensure the host device supports QSFP transceivers and 40 Gbit/s operation before installation. With the network equipment powered down or following the vendor's hot-swap procedure, insert the BlueOptics QSFP-4X10G-LR-S into a compatible QSFP port until it seats securely. Connect single-mode fiber cables terminated for 1310 nm operation to the transceiver's optical interface and verify link status through the host device's management interface. Follow standard optical safety practices when handling fiber connections.

Recommendations

Verify compatibility with the switch or router vendor's supported transceiver list and ensure fiber connector types and patching meet single-mode 1310 nm requirements. Monitor link performance and temperature after installation, and store spare modules in anti-static packaging away from excessive humidity and dust.
