LU 90 01204 40GBase-SR4 MMF
The LU 90 01204 is a multi-mode fiber SFP module capable of 40Gbps per second.
It uses an MTP/MPO-12 connector and can therefore NOT be used with 'standard' SMF LC-LC patch cables like we know from other Luminex fiber modules.
40G modules are essentially 4x 10Gbps modules combined in 1 transceiver. This means that 4 signals are carried between the modules in each direction, 8 total.
The LU 90 01203 achieves this by using 8 different fiber strands in total: 4x TX and 4x RX. These are combined into 1 MPO-12 UPC connector (Multi-Fiber Push-On Ultra Physical Contact). These are typically color-coded in blue or magenta.
The benefit of this method is that this module can be used to breakout / fanout a 40G SFP port into 4x 10Gbps.
2x LU 90 01204 SFP modules can be interconnected using a female-to-female (unpinned) MTP®/MPO Type B Cable (Cross over).

DAC (Direct attach copper) cables
Direct Attach Copper (DAC) cables are passive cables with a SFP module on each end. They offer robust connections over a short distance. Since this is a passive solution, it is very cost-effective and therefore ideal for interconnections within 1 rack.
DAC cables do not have DDM (Digital Diagnostics Monitoring), which means that information like temperature or signal strength is not available. Because of the simplicity of DAC cables, this is not an issue.
