QSFP Transceiver Module BlueOptics QSFP-40G-PLR4-IB-BO 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-IB-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s links over single-mode fiber at a nominal wavelength of 1310 nm. The module is compatible with MPO/MTP connectors and follows MSA QSFP mechanical and electrical specifications to ensure interoperability with hardware platforms that support the original form factor. The transceiver integrates transmitter and receiver elements and offers an MTBF of 1,000,000 hours while weighing approximately 40 g, making it suitable for dense, high-speed network deployments where space and reliability matter.

Advantages

The module supports a standardized QSFP interface and MPO/MTP connectivity, enabling straightforward integration into switches, routers and optical patching systems that accept QSFP modules. Its single-mode 1310 nm optics are suitable for long-reach links up to several kilometers depending on system margin and cabling. Compliance with MSA ensures mechanical and electrical compatibility, while the reported MTBF indicates a design focus on long operational life and reduced maintenance intervals.

Suitable for

• Interconnecting switches and routers in data center aggregation or spine layers
• High-speed uplinks between network devices supporting QSFP modules
• Optical links in storage area networks and high-performance computing clusters
• Replacing or upgrading existing QSFP-PLR4 transceivers in compatible hardware

Key specifications

• Interface type: QSFP form factor with MPO/MTP optical connector
• Nominal wavelength: 1310 nm (Tx/Rx)
• Maximum data transfer rate: 40 Mbit/s
• Fiber type: single-mode fiber (SMF)
• Weight: approximately 0.04 kg
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the module into a compatible QSFP slot on a switch, router or other network device while the host is powered down or following the vendor’s hot-swap procedure. Connect single-mode MPO/MTP patch cords between transceivers or to the appropriate patch panel. Verify link status and diagnostics through the host device management interface; if supported, read digital diagnostic monitoring (DDM/DOM) parameters to confirm optical power, temperature and supply values. Follow the hardware vendor’s guidance for optical power budgets and passband alignment when deploying across longer distances.

Recommendations

Use high-quality single-mode MPO/MTP patch cords and ensure connectors and fiber paths are clean to maintain signal integrity. Confirm that the target hardware supports third-party QSFP modules and DDM/DOM functions if remote diagnostics are required. For longer links, verify end-to-end loss budget and consider using manufacturer-recommended patch panels or attenuation where necessary.
