    • Cellular signals or other wireless signals/messages are introduced into a building or to an outside location by transmitting packets corresponding to those signals over a data network and low cost cables to designated locations within the data network. Once the designated packets containing the signals reach the destination, they are then broadcast over the air to a terminal capable of receiving the wireless message. In a first embodiment, an in-building gigabit Ethernet network, such as that currently existing presently in many buildings, is used to distribute radio signals indoors. Instead of transmitting the radio signals over the air from a repeater connected to a base station, coded baseband signals generated by the coding processor (e.g., a CDMA Modem Unit) in the base station are packetized and sent over the Ethernet network to radio processing equipment and antennas distributed throughout the building. The radio processing equipment strips the packet headers from the baseband signal packets so those signals can be broadcast via the antennas to one or more mobile terminals.
    • 蜂窝信号或其他无线信号/消息通过在数据网络上传送与这些信号相对应的数据包和低成本电缆到数据网络中的指定位置而被引入建筑物或外部位置。 一旦包含信号的指定分组到达目的地,则它们然后通过空中广播到能够接收无线消息的终端。 在第一实施例中,使用诸如目前在许多建筑物中当前存在的建筑物内的千兆以太网网络来在室内分配无线电信号。 代替从连接到基站的中继器通过空中传送无线电信号,由基站中的编码处理器(例如,CDMA调制解调器单元)生成的编码基带信号被分组并通过以太网发送到无线电处理设备 和分布在整个建筑物的天线。 无线电处理设备从基带信号分组剥离分组报头,从而可以经由天线将信号广播到一个或多个移动终端。

    • A multiple optical fiber connector is constructed from a unitary planar substrate having two surfaces with 1) multiple fiber holes and 2) plural alignment regions located in opposing relationship to each other along edges of the substrate, the multiple fiber holes and plural alignment regions being formed substantially perpendicular to and between the surfaces of the substrate using photolithographical techniques. Each optical fiber is permanently mounted through one of the holes in one surface of the substrate so that the end of each fiber is substantially flush with the other surface of the substrate. Alignment posts which are positioned against the alignment regions and mounted substantially perpendicular to the surfaces of the substrate are used to align optical fibers mounted in the substrate with optical fibers mounted in a substrate of a mating connector.

    • A Pockels cell driver useful to operate the Pockels cell as an optical shutter to select one or more laser pulses out of a train of laser pulses when the Pockels cell is placed between crossed polarizers. The Pockels cell is connected through a storage capacitor, of higher capacitance than the capacitance of the Pockels cell, directly to a high voltage source and is charged to high voltage. The cell is charged and the storage capacitor is discharged through a microwave triode which is triggered by an avalanche transistor switch circuit. By directly charging the Pockels cell, lower currents are used than with conventional Pockels cell drivers using transmission lines to connect to the Pockels cell and gas filled tubes to switch a pulse-forming line. The Pockels cell shutter can be operated to provide transmission intervals for the laser pulses of the order of a nanosecond at high repetition rates, up to 10 KHz, without jitter in the timing of the transmission interval and for long periods of time without frequent need for replacement of the microwave triode.
    • 普克尔斯单元驱动器可用于将普克尔斯单元作为光学快门来操作,以便当普克尔斯单元置于正交偏振器之间时,选择激光脉冲串中的一个或多个激光脉冲。 Pockels电池通过比Pockels电池电容高的电容器直接连接到高电压源并充电到高电压。 电池被充电,并且存储电容器通过由雪崩晶体管开关电路触发的微波三极管放电。 通过直接对Pockels电池充电,使用比传统的Pockels电池驱动器更低的电流,使用传输线连接到Pockels电池和充气管,以切换脉冲形成线。 可以操作Pockels单元快门,以提供高达10KHz的高重复频率的毫秒级的激光脉冲的传输间隔,而在传输间隔的定时和长时间段内没有抖动,而不需要频繁地 更换微波三极管。
