QSFP-transceiver BlueOptics QSFP-40G-SR4-DE-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-DE-BO is a QSFP fiber optic transceiver module for multi-mode fiber links. It supports up to 40 Mbit/s data transfer at an 850 nm wavelength, uses an MPO/MTP connector and is housed in metal for mechanical durability. The module is compact and lightweight (approximately 20 g) and is designed to deliver long operational life with an MTBF of 1,000,000 hours. It follows MSA QSFP mechanical and electrical standards to ensure interoperability with hardware platforms that support compatible QSFP modules.

Advantages

The metal housing increases robustness while the QSFP interface provides a standardized electrical and mechanical form factor for high-density installations. Operating at 850 nm over multi-mode fiber enables short-range 40G links with MPO/MTP connectivity. The transceiver includes digital diagnostic monitoring capability when supported by the host device, enabling remote readout of operating parameters. A high MTBF rating indicates lower maintenance requirements and predictable service life for deployed links.

Suitable for

• Short-range 40G multi-mode fiber connections in data centers
• Inter-switch and switch-to-server uplinks where QSFP ports are available
• High-density networking equipment requiring MPO/MTP connectivity

How to use

Install the QSFP transceiver into a compatible QSFP port according to the host equipment manufacturer’s instructions, taking care to align and secure the module fully. Use MPO/MTP multi-fiber patch cords and appropriate multi-mode fiber cabling to connect to the corresponding transceiver or patch panel. Ensure the host device supports the transceiver’s digital diagnostic monitoring if that feature is required. Verify link status through the host device’s management interface after installation and observe appropriate electrostatic discharge (ESD) precautions during handling.

Recommendations

For reliable performance, use high-quality OM3/OM4 multi-mode fiber and MPO/MTP patch cords, confirm host compatibility with QSFP modules and DDM/DOM support, and follow the equipment vendor’s guidelines for transceiver firmware and port configuration.
