Abstract: The present invention provides a differential paired cable with compensation functions, including: a first wire; a second wire; a first insulating layer; a second insulating layer; a ground wire; and a shielding layer. By controlling at least one of a length difference between the first insulating layer and the second insulating layer exposed outside of the shielding layer to be greater than 0.1 mm, a diameter difference between the first wire and the second wire to be greater than 0.005 mm, and a length difference between a welding portion of the first wire and a welding portion of the second wire to be greater than 0.05 mm, a signal transmission rate of one of the first wire and the second wire is compensated, so as to reduce an intra pair skew of the differential paired cable.

Abstract: An energy storage battery system with overlapping copper buses is provided, including a casing, a plurality of battery modules, an upper cover, and a plurality of copper buses. The casing has a positive electrode and a negative electrode. The battery modules are arranged in the casing. The upper cover is disposed in the casing and located above the battery modules. The copper buses are disposed on the upper cover and are electrically connected to the battery modules, the positive electrode and the negative electrode. As such, the copper buses can be arranged according to the shape of the space of the upper cover, thereby achieving the effect of saving space. Furthermore, the copper buses are easy to install on the upper cover and do not require manual arrangement of cables, thereby effectively reducing the assembly process and man-hours.

Abstract: A transmission cable includes a conductor and a composite layer. The composite layer is formed by having an inner surface of an outer wrap layer adhered to an outer surface of an inner wrap layer with a glue material. The composite layer wraps the conductor and an inner surface of the inner wrap layer is in contact with an outer surface of the conductor. The inner wrap layer is made of polytetrafluoroethylene with a foaming degree of 65% to 77%, and the outer wrap layer is made of polyimide. The composite layer is made by drawing cable at a rate of 0.1-0.5 m/min and taping with an overlap percentage between 32% and 37% during a wrapping process.

Abstract: An optical transceiver system includes a PAM4 conversion device, a light emitting device, a light receiving device and an interface unit. The light emitting device is coupled to the PAM4 conversion device and receives a first PAM4 signal from the PAM4 conversion device. The light receiving device is coupled to the PAM4 conversion device and transmits a second PAM4 signal to the PAM4 conversion device. The interface unit is coupled to the PAM4 conversion device through an active electrical cable device and transmits a first NRZ signal to the PAM4 conversion device. The first NRZ signal is converted into the first PAM4 signal by the PAM4 conversion device, and the second PAM4 signal is converted into a second NRZ signal by the PAM4 conversion device, and the second NRZ signal is transmitted to the interface unit.
