    • A relation between a light input power monitor value of an optical transmission signal before passing through a fiber and an input signal amplitude monitor value is recorded in advance in a storage device. Next, actual optical-transmission-waveform is inputted into an optical receiver module, and then comparisons between a light input power monitor value and an input signal amplitude monitor value, and respective monitor values in the case without having the waveform distortion as described above are performed in an operation device to calculate a waveform distortion value. According to the waveform distortion level calculated herein, an optimum threshold value and an optimum phase adjusting value, at which receiver sensitivity is maximized, are calculated in the operation device to control a threshold-value adjusting circuit and a phase-value adjusting circuit, thereby a threshold value and a phase value that are optimum for an input distortion level can be established.

    • To provide economical high-speed optical communications through an optical module a silicon substrate with a ball lens and semiconductor luminescence element mounted thereon, and a laser driver IC are provided. A silicon subassembly includes a silicon substrate with a pyramidal cavity etched into the substrate near its edge. A ball lens is precision-mounted in the pyramidal cavity by bonding it at multiple points. This provides a high-strength connection and a small, inexpensive silicon substrate. Also provided on the silicon substrate is a semiconductor luminescence element and a slit on the opposite side of the ball lens. The slit enables collimated light emitted from the ball lens to be optically coupled without being blocked or reflected by the substrate. The semiconductor luminescence element and its laser driver IC are placed in close proximity to each other, and ribbon wires are kept short (approximately 300 &mgr;m) to reduce signal line impedance mismatch for high-speed transmission.
    • 为了通过光学模块提供经济的高速光通信,提供了安装有球透镜和半导体发光元件的硅衬底和激光驱动器IC。 硅子组件包括硅衬底,其具有在其边缘附近蚀刻到衬底中的锥体腔。 球形镜头通过在多个点处粘合而精确安装在锥体腔中。 这提供了高强度的连接和小的廉价的硅衬底。 在硅衬底上还设置半导体发光元件和在球透镜的相对侧上的狭缝。 狭缝使得从球形透镜发射的准直光被光学耦合,而不被基板阻挡或反射。 半导体发光元件及其激光驱动器IC彼此靠近放置,并且带状线保持短路(约300mum),以减少用于高速传输的信号线阻抗失配。

    • A signal processing circuit which enables an error bit to be set simply without causing an increase in the size of the circuit even if the packet size is changed and which enables realization of stable operation without the system stopping even if the value of the time stamp is impossible. A pre-reception processing circuit decides if a received packet is normally continuous or discontinuous from data in the DBC region of the CIP header. When deciding it is discontinuous, it sets an error bit ERM allocated to one bit of the upper significant 7 bits of the source packet header to “1”, and writes this in an FIFO. A post-reception processing circuit, when reading from the FIFO, outputs the data stored in the FIFO to the application side when the error bit ERM is “0” and resets the error bit and outputs a dummy error packet when the error bit EMR is “1”.
    • 一种信号处理电路,即使分组大小发生变化也能够简单地设定错误位而不引起电路尺寸的增加,即使时间戳的值为 不可能。 预接收处理电路判定所接收的分组是否正常连续或不连续的来自CIP头部的DBC区域中的数据。 当判定为不连续时,它将分配给源包头的高有效7位的一位的错误位ERM设置为“1”,并将其写入FIFO。 当从FIFO读取时,接收后处理电路当错误位ERM为“0”时将存储在FIFO中的数据输出到应用端,并且当错误位EMR为“0”时,复位错误位并输出虚拟错误包 “1”。
