Abstract: A fiber optic connector assembly and method for venting gas inside in a fiber optic connector sub-assembly. The fiber optic connector assembly includes a connector sub-assembly including a ferrule and a ferrule holder having a passage extending therethrough. A stiffener tube having a tube body disposed about a portion of at least one optical fiber supports insertion of the optical fiber into the ferrule holder passage. The stiffener tube contains at least one opening in its tube body configured to vent gas trapped inside the stiffener tube during assembly. In this manner, the trapped gas does not form a gas pocket in the bonding agent, which could compromise bonding among the optical fiber, stiffener tube, and connector sub-assembly.

Abstract: A method and a corresponding system for characterizing the performance of a clock and data recovery circuit in a digital transceiver is presented. The method comprises phase modulating a jitter-free data signal by a testing signal having added data jitter and measuring the time the clock and data recovery system takes to achieve bit lock of a phase modulated signal. Data uncorrelated timing jitter corresponding to a user defined probability distribution is included in the jitter testing signal. Utilization of a variable probability distribution in generating data uncorrelated timing jitter, as provided by the present invention, allows for greater flexibility and accuracy in clock and data recovery circuit testing and characterization.

Abstract: A circuit for pre-emphasis in data serialization. The circuit has a signal delayline to incrementally delay a serialized signal, producing a delayed serialized signal. The circuit has a one bit generator circuit, which determines the interval between receipt of one bit and a second bit. The one bit generator circuit has a strobe delayline to incrementally delay a strobe signal, producing a delayed strobe signal, a logical gate to compare the delayed strobe signal with a second strobe signal, and a logical component to determine how long the delayed strobe signal was delayed before it matched the second strobe signal. The circuit also has a comparison gate to detect transition points in the serialized signal by comparing the delayed serialized signal with the serialized signal. The circuit also has a current source to provide increased current for the serialized signal at the detected transition points.

Abstract: Disclosed are methods that enable communications to be established regardless of the presence of communications blockers, e.g., firewalls and NATs, in the path between two computing devices. Two devices each establish communications with a rendezvous service. Through the service, the devices signal each other to set up direct, peer-to-peer communications between themselves. If the devices fail to establish direct communications, then they invoke a relay service that provides the illusion of direct communications. In another aspect, an originating device attempts to establish communications with a recipient, using an address and port number associated with the recipient. If that attempts fails, possibly because a firewall is blocking communications, then the originating device retries using a port normally held open by firewalls. If this attempt also fails, then the originating device invokes the services of a proxy to negotiate a port acceptable for use by the recipient and by any intervening firewalls.

Abstract translation: 公开了能够建立通信的方法，而不管在两个计算设备之间的路径中是否存在通信阻塞器，例如防火墙和NAT。 两个设备各自建立与会合服务的通信。 通过服务，设备相互信号，建立起彼此直接的对等通信。 如果设备无法建立直接通信，则调用中继服务，提供直接通信的错觉。 在另一方面，始发设备尝试使用与接收者相关联的地址和端口号与接收者建立通信。 如果尝试失败，可能是因为防火墙阻止通信，则始发设备将使用通常由防火墙打开的端口重试。 如果此尝试也失败，则始发设备调用代理服务以协商一个可接受的端口以供任何中间的防火墙使用。
