BlueOptics QSFP-40G-PLR4-AL-BO network transceiver module Fiber optic 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-AL-BO is a fiber optic QSFP network transceiver module designed for single-mode fiber links. It supports a maximum data transfer rate of 40 Mbit/s over a nominal wavelength of 1310 nm, implements an MPO/MTP connector according to MSA standards, and is intended for use in QSFP-compatible slots of network switches, routers and storage systems. The module is supplied as a single unit and has a listed MTBF of 1,000,000 hours, with a lightweight form factor of approximately 40 g.

Advantages

The module follows MSA QSFP form-factor specifications to provide electrical, mechanical and functional interoperability with supported hardware. It integrates transmitter and receiver paths at 1310 nm for simultaneous optical transmit and receive operation via single-mode fiber. Digital diagnostics (DDM/DOM) support enables real-time monitoring of key operating parameters when the host hardware also supports these functions. Designed and tested for compatibility with major platforms that accept QSFP 40GBASE-PLR4 optics, the module is intended to offer stable long-term operation with an MTBF aligned to professional networking environments.

Suitable for

• 40G single-mode fiber uplinks between switches and routers
• High-speed links in data center switching and aggregation
• Interconnects for storage systems and high-performance network appliances

How to use

Install the BlueOptics QSFP-40G-PLR4-AL-BO module into a compatible QSFP port following the host device manufacturer’s insertion and hot-swap guidelines. Connect an MPO/MTP single-mode fiber patch cord to the module and route the other end to the matching MPO/MTP transceiver or patch panel. Verify link parameters and enable any required interface settings in the switch or router operating system. If the host supports DDM/DOM, use the network management interface to monitor supply voltage, laser bias current, output power, received power and module temperature for ongoing diagnostics.

Recommendations

Ensure the host device explicitly supports QSFP 40GBASE-PLR4 MSA optics and that MPO/MTP cabling is rated for single-mode use. Observe ESD precautions during handling and avoid bending fiber beyond manufacturer-recommended radii. For best optical performance, use matched BlueOptics patch cords or equivalent certified single-mode MPO/MTP assemblies and validate link integrity after installation.
