40 Gbps QSFP+ Transceiver for Short-Range Links

This Brute Networks module delivers 40 Gbps over multi-mode fibre at 850 nm with a 150 m reach. It fits a QSFP+ slot on compatible Juniper routers, switches or servers and is coded for 100 % Juniper compatibility.

MTP/MPO Connector and Digital Monitoring Included

The transceiver uses an MTP/MPO connector for four-lane parallel optics and provides digital output monitoring for real-time link health. MSA compliance ensures mechanical and electrical interchangeability with other MSA-standard modules.

Verify Slot Type, Fibre Grade and Temperature Range

Confirm the host device accepts QSFP+ form-factor optics and supports 850 nm multi-mode fibre rated for 150 m. The operating range is 0 °C to 70 °C, so ensure the installation environment stays within these limits.

Questions about this item

Does the MTP/MPO connector or the 850 nm optics need periodic cleaning or replacement?

The MTP/MPO connector and 850 nm optics are passive components with no moving parts; they do not require scheduled replacement. Inspect and clean the ferrule end-faces only if link errors appear or during planned fibre maintenance.

What is the first limit reached when the transceiver runs continuously at 40 Gbps?

The 150 m reach on multi-mode fibre is the primary distance limit; the module is rated for continuous operation up to 70 °C case temperature, so thermal shutdown would occur only if chassis airflow cannot keep the case below that threshold.

How loud or hot does the module get inside a switch that runs all day?

The transceiver has no fan and produces no audible noise; its commercial temperature rating of 0 °C to 70 °C means the case will warm to the surrounding chassis temperature but stays within specification when the host provides normal airflow.
