An optical communications system and method are provided in which multiple parallel optical communications modules are mid-plane mounted on a PCB motherboard. Each module is connected to an optical fiber ribbon cable. The modules are configured to have very low profiles and/or to provide an angular coupling of the ribbon cable to the module. In both cases, the module configurations obviate the need to leave a significant amount of space between a module and the one behind it for the purpose of providing room for the ribbon cable to exit the module without the cable being bent beyond its minimum bend radius. This feature allows the module mounting density on the motherboard PCB to be very high and allows the modules to be mounted closer to their respective hub ICs, which increases mounting density and allows the modules to be mounted closer to their respective hub ICs.
