Abstract: An optical transmitter/receiver unit having an optical connector with an optical device array block and a multi channel optical fiber block is presented. The optical device array block includes at least one optical device for converting an electric signal to an optical signal or for converting an optical signal to an electrical signal. The optical devices is mounted on a silicon optical bench having a series of grooves for inserting, attaching and aligning each optical device. The optical device array block can be optically coupled to a multi channel optical fiber block that includes at least one optical fiber for transmitting an optical signal, the optical fiber being mounted in V-shaped grooves on a silicon V block. The V-shaped grooves on the V-block and the mounting grooves on the silicon optical bench allow for accurate alignment of each optical fiber with corresponding optical devices.

Abstract: The present invention relates to a module for parallel transmission and reception of an optical signals, and particularly a miniaturized module with a fixed optical coupler and a detachable electric connector is disclosed. A miniaturized optical signal transmission module according to the present invention comprises an electrical connector for coupling electric signals to a circuit board; an array of optical devices coupled to metal leads, the array of optical devices converting between optical signals and the electric signals; an optical fiber array block fixedly and optically coupled to the array of optical devices for transmitting the optical signals, wherein the metal leads are detachably coupled to the electrical connector part. The optical module can be miniaturized so that the entire system can be miniaturized. Accordingly, many advantages according to the miniaturization of the entire system can be obtained.
