Patent number: 8998511Abstract: In aligning ends of optical fibers, e.g. for performing a prealignment of ends of large mode area double-clad fibers (LMA-DCFs) in order to thereafter perform a core alignment process, in a fiber optic fusion splicer a best, optimum or near optimum position or setting of the optical system for observing the self-focusing effect is first determined and then the very alignment operation may be performed using the determined setting.

Patent number: 8824280Abstract: A system and method for implementation of a process that propagates a link status across a media converter system implemented in a telecom and/or data com network is provided. More specifically, the system comprise XAUI and PMA/PMD interfaces that support both a copper cable and the different types of SFP+/SFP fiber-optic pluggable modules for accessing a host system and a remote link partner, respectively. With the method, the link statuses at both the copper and fiber-optic link sides of the media converter system are being monitored, such that a change of link status at one side of the media converter system will automatically be propagated across the media converter system to the other side, by dynamically enabling or disabling a respective XAUI or PMD transmitter at the opposite side of a physical layer device (PHY) of the media converter system.Type: GrantFiled: June 17, 2010Date of Patent: September 2, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Wei-Ping Huang

Patent number: 8788722Abstract: A method handling a pluggable module selectable from a plurality of pluggable modules is executable at a media converter system of a network configuration. The method provides for automatically enabling of a disabled channel or disabling of an enabled channel of the media converter system when the pluggable module is attached to the media converter system, wherein the suggested channel enabling/disabling feature is executed on the basis of a correlation between module specific information extracted from the respective pluggable module and corresponding information extracted via the media converter system. An arrangement for executing the suggested method is also provided.Type: GrantFiled: June 17, 2010Date of Patent: July 22, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Wei-Ping Huang

Patent number: 8596888Abstract: In aligning ends of optical fibers, e.g. ends of large mode area double-clad fibers (LMA-DCFs), in a fiber optic fusion splicer the best position of the object plane of the optical system for observing images of the cores of the fiber ends are first determined by maximizing the contrast of the core image, in particular the core image peak in intensity profiles. The alignment process may be performed by adjusting the offset distance between the observed cores in some suitable way, e.g. by using a cascade technique. In e.g. a process for prealigning the fiber ends the self-focusing effect of optical fibers can be used to first determine the best object plane position for observing the self-focusing effect and then the very pre-alignment operation can be performed. This may extend the range of image analysis allowing e.g. that alignment, in particular core alignment, can be performed without requiring direct information showing the position of sides or edges of the claddings in captured pictures.Type: GrantFiled: December 29, 2006Date of Patent: December 3, 2013Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Wei-Ping Huang, Kjell Ahlstedt
