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

The BlueOptics QSFP-40G-SR4-LS-BO is a QSFP fiber optic transceiver module designed for short-range, high-speed data links. It provides a maximum aggregated data rate of 40 Mbit/s over multimode fiber using an 850 nm wavelength and uses an MPO/MTP connector in a compact metal housing. The module supports common 40GBASE-SR4 applications and is compatible with hardware that accepts MSA-compliant QSFP transceivers. With a reported MTBF of 1,000,000 hours and a lightweight design, the module is intended for deployment in data centers and high-performance network environments where predictable optical performance and mechanical durability are required.

Advantages

The transceiver offers a QSFP interface in a metal casing for robust mechanical protection and easy hot-plug installation. It implements the 850 nm transmitter and receiver pair optimized for multimode fiber transmission and includes MPO/MTP connectivity following MSA standards to ensure interoperability. Built-in digital diagnostics support remote monitoring of key parameters to assist with maintenance and troubleshooting. The product's design and component selection target long service life and high availability in continuous-operation environments.

Suitable for

• Short-reach 40G Ethernet links in data centers (40GBASE-SR4)

How to use

Install the BlueOptics QSFP-40G-SR4-LS-BO into a compatible QSFP slot on the switch, router, or other host device while the host supports MSA-compliant QSFP modules. Connect the MPO/MTP multimode fiber patch cord to the transceiver and route it to the corresponding port or patch panel. Ensure the link uses appropriate OM3/OM4 multimode fiber for the required distance and that the host device firmware supports the transceiver's diagnostics functions if monitoring is required. Handle the module and fiber connectors with appropriate ESD precautions and keep optical ports covered when not in use.

Recommendations

For reliable short-range 40G performance, use OM3 or OM4 multimode fiber and quality MPO/MTP patch cords, verify compatibility with the host device, and enable digital diagnostics monitoring where supported to track supply voltage, optical power, bias current and temperature for proactive maintenance.
