What this module does

The Brute Networks Brocade 40G-QSFP-LR4 is a QSFP+ transceiver that operates at a 40 Gbps transfer rate over single-mode optical fibre. It uses a 1310nm wavelength to reach distances up to 10km and complies with the 40GBASE-LR4 standard. The unit is built for commercial temperature ranges from 0 to 70°C and carries standard LED indicators for power, link, duplex and speed.

Who this suits and who it does not

This transceiver suits network engineers extending Brocade NetIron MLX-16, MLX-32, MLX-4, MLX-8 or ICX 7750-2 equipment across campus or metro links. Buyers needing shorter-reach multimode optics, higher-density breakout cables or direct-attach copper assemblies should look at other form factors because this module is fixed to single-mode LC connectivity and long-range operation.

Deciding specification

The single specification that determines fit is the 10km reach at 1310nm over single-mode fibre with a 40 Gbps line rate. If the link budget, distance or fibre type differs from these parameters, the module will not operate correctly.

Questions about this item

Should I pick the 40 Gbps LR4 module or a shorter-range alternative?

Choose this 40 Gbps LR4 transceiver when the link must span up to 10 km over single-mode fibre; shorter-range SR4 modules only reach 100 m.

What does the 40 Gbps rating deliver in a live switch?

The module provides a full 40 Gbps lane across four 10 Gbps wavelengths, giving line-rate throughput on compatible Brocade NetIron MLX and ICX 7750 ports.

Which QSFP+ standard does this transceiver follow and what distance does it guarantee?

It complies with the 40GBASE-LR4 MSA specification and guarantees error-free operation up to 10 km (6.2 miles) at 1310 nm over single-mode fibre.
