The present invention discloses an optical communication module comprising a second mode supporting a data transfer of USB 3.0 standard and a third mode supporting a data transfer of USB 2.0 standard, and the second mode comprises A mode and B mode with a different power consumption and supported data rate, and a detect unit operative to detect idle state of the data traffic on the data path of USB 3.0 standard to determine to stay on the A mode or enter to the B mode automatically during operation in the second mode. The control circuitry can work in different modes to support different status of devices attachment and removal, different data rate of USB 2.0 and 3.0 standards; and it can real time monitor the data traffic to switch different modes to save power consumption. The present invention also discloses a USB cable and a processing method of data transfer for an optical communication module.

Optical communication module, universal serial bus cable with the same and processing method of data transfer thereof

A method for manufacturing a polymer miniature lens on a substrate with the lens forming pattern, and the liquid polymer is dispensed therein. The lens forming pattern having a periphery area and an interior area, most portion of the periphery area having a property of confining liquid polymer, while the interior area having at least one portion exposing the surface of the substrate; depositing liquid polymer onto the lens forming pattern; and curing the liquid polymer after the liquid polymer reaches equilibrium shape and is confined to the periphery area. The invention also discloses a collimator including the polymer miniature lens.
