QSFP-transceivermodule BlueOptics QSFP-40G-PLR4-NK-BO 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-NK-BO is a QSFP fiber optic transceiver module engineered for 40 Mbit/s data transfer over single-mode fiber using a 1310 nm wavelength. The module is compatible with QSFP interfaces, features an MPO/MTP connector for multi-fiber connections and is designed for use in high-performance network equipment. With a reported mean time between failures (MTBF) of 1,000,000 hours and a lightweight construction of approximately 40 g, the transceiver is intended for reliable, long-term operation in data centers and enterprise networking environments.

Advantages

The transceiver provides a QSFP interface for compact, hot-pluggable installation and uses 1310 nm optical components suitable for single-mode links. Built and tested according to MSA standards, the module supports simultaneous transmit and receive operation via MPO/MTP connectivity and includes digital diagnostics monitoring (DDM/DOM) capability for remote status information. Its low weight and standardized mechanical design simplify installation and replacement in compatible hardware platforms.

Suitable for

• 40 Mbit/s fiber links in data centers and aggregation layers
• Interconnects between switches, routers and storage systems supporting QSFP
• Single-mode optical runs requiring MPO/MTP multi-fiber connectors

How to use

Insert the BlueOptics QSFP-40G-PLR4-NK-BO into a compatible QSFP slot on your switch, router or storage device while the host is powered down or according to the host vendor's hot-plug procedures. Connect an MPO/MTP single-mode patch cable between the transceiver and the remote transceiver or patch panel. Verify link status and, if available, read digital diagnostics parameters through the host management interface to confirm optical power, temperature and supply voltage are within expected ranges. Follow the hardware vendor's guidelines for firmware or compatibility settings when using third-party transceivers.

Recommendations

Use high-quality single-mode MPO/MTP patch cords and ensure endpoints support the 40 Mbit/s 1310 nm signalling. Confirm DDM/DOM support in the host device to enable remote diagnostics. Maintain clean connector end-faces and follow standard ESD and fiber handling procedures during installation and maintenance.
