Patent number: 6402389Abstract: The present invention relates to an angled opto-mechanical connector (10) and to a manufacturing process for the same. The connector (10) comprises a fixture (1) with straight and parallel grooves (2, 3) of two sizes running on the upper side of the fixture (1) from a first fixture side (1a) to a second fixture side (1b). A lid (4) is fastened above the fixture (1). Fibre ends (8a) of optical fibres (8) are placed in the capillaries which are formed between the smaller grooves (2) of the fixture and the lid (4) in such a way that they stick out through the side of the fixture (1b). A plastic capsule (11) encloses the fixture (1), the lid (4) and the fibres (8) completely or partially. The fibres (8) stick out from the plastic capsule (11) in a direction separated from that defined by the grooves of the fixture. The connector (10) can also have an opto-mechanical interface of the above mentioned type at its other end (10b).Type: GrantFiled: April 29, 1997Date of Patent: June 11, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Odd Steijer, Christer Moll, Bengt Lindström, Christian Vieider, Paul Eriksen, Jan-Åke Engstrand, Olle Larsson, Håkan Elderstig

Patent number: 6338983Abstract: In encapsulating an optocomponent, a leadframe is used for the electrical connection of the component, the leadframe having a flag, to which the main body of the optocomponent is attached. The flag is located asymmetrically at an outer edge of the leadframe and is, in the encapsulating operation, placed close to a sidewall in a mold cavity in a mold. In this way, an optical interface of standard type can be obtained in the wall of the capsule. Further, the flag is flexibly attached, by zigzag-shaped bridges, to other portions of the leadframe so that the flag and thus the optocomponent will have a possibility to be resiliently and flexibly displaced a little at the positioning thereof in the mold cavity in the mold in relation to the other portions of the leadframe, in particular to its outer frame portions and bridge portions.Type: GrantFiled: May 18, 2000Date of Patent: January 15, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Odd Steijer, Paul Eriksen

Patent number: 6326680Abstract: In manufacturing an encapsulated optocomponent, the optocomponent is embedded in a plastics material. The optocomponent has guide grooves on one of its surfaces in which guide pins are to extend so that the encapsulated optocomponent will obtain an optical interface of standard type. For the encapsulating operation guide pins are placed in a mold cavity in a mold half and the optocomponent is placed in the cavity in the mold, so that the guide pins are engaged in the guide grooves and ar accurately inserted therein. To achieve this effect, a resilient or elastic force such as from plunger is applied to the other side of the optocomponent, so that it is pressed with some force against the guide pins. The cavity in the mold is then closed by placing a second mold half on top after which the encapsulating material can be introduced in the closed cavity in the mold.Type: GrantFiled: August 6, 1999Date of Patent: December 4, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Odd Steijer, Hans-Christer Moll, Paul Eriksen, Jan-Åke Engstrand

Patent number: 6173098Abstract: The present invention relates to a manufacturing method for an opto-mechanical connector (10) and to the connector itself. The invention includes that a fixture (1) is manufactured with straight and parallel grooves (2,3) running on the upper side of the fixture (1) from a first fixture side (1a) to a second fixture side (1b), and which grooves (2,3) are intended partly for optical fibers and partly for guide pins.

Patent number: 6072229Abstract: In encapsulating an optocomponent a leadframe (51) is used for the electrical connection of the component, the leadframe having a flag (53), to which the main body of the optocomponent is attached. The flag (53) is located asymmetrically at an outer edge of the leadframe and is, in the encapsulating operation, placed close to a sidewall in a mould cavity in a mould. Thereby an optical interface of standard type can be obtained in the wall of the capsule. Further, the flag (53) is flexibly attached, by means of zigzag-shaped bridges (67), to other portions of the leadframe so that the flag and thus the optocomponent will have a possibility to be resiliently and flexibly displaced a little at the positioning thereof in the mould cavity in the mould in relation to the other portions of the leadframe, in particular to its outer frame portions (61) and bridge portions (59).Type: GrantFiled: June 30, 1997Date of Patent: June 6, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Odd Steijer, Paul Eriksen

Patent number: 6008455Abstract: At a signal transmission rate of 1 Gb/s, the "bit time" is 1 ns. This corresponds to a bit length in an optical fibre of 0.2 m. In view of the fact that skew shall not exceed one-tenth of a bit length, this means that length differences between different conductors in a transmission line may not exceed 2 cm. With the intention of minimizing the skew that would thus otherwise occur in a transmission line, the transmission line (1) and its conductors (2) have been joined to form a ribbon cable or flat cable where the length difference (5) between different conductors (2) in the transmission line does not exceed 2 cm. By providing transmission lines, such as rolled-up flat ribbon cables for instance, which have been previously cut to precise and appropriate lengths, such as lengths of 10, 20, 30 m for instance, with a largest length deviation between different conductors of .+-.1 cm, skew can be minimized when using the cables.Type: GrantFiled: January 27, 1997Date of Patent: December 28, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Bengt Lindstrom, Hans-Christer Moll, Odd Steijer

Patent number: 5985185Abstract: In encapsulating an optocomponent with a plastics material, an MT-connector compatible interface is obtained having bores for guide pins in the wall of the capsule and optical connection surfaces. These bores are obtained from mold cavity guide pins that are used for aligning the optocomponent in a mold cavity in a mold in the molding operation of the encapsulating material on top of the component. In order to achieve a good accuracy in the positioning of the component during the molding operation, the mold guide pins are as short as possible and end directly behind the component where they are supported by projections extending from each mold half. Thus, cavities are created extending straight through the capsule behind the component. The cavities allow that the guide pin bores are cleansed and that material residues are removed after the molding operation. Further, the cavities can be used for spring clamps for retaining the optocomponent capsule at an optical connector having a similar interface.Type: GrantFiled: July 14, 1997Date of Patent: November 16, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Odd Steijer, Hans-Christer Moll, Paul Eriksen, Jan-.ANG.ke Engstrand

Patent number: 5818990Abstract: An encapsulated optocomponent (1) comprises a single-crystal silicon wafer (3) and waveguides (9) located thereon, which at least partly are manufactured by means of process methods taken from the methods for manufacturing electronic integrated circuits. The waveguides (9) extend from an edge of the optoelectronic component (1) to an optoelectronic, active or passive component (11) attached to the surface of the silicon wafer (3). Over the region for connecting the waveguides (9) to the optoelectronic component (11) a transparent plastics material is molded (17), for instance an elastomer, having a refractive index adjusted to improve the optical coupling between the waveguides (9) and the optoelectronic component (11). The molding (17) covers advantageously all of said component (11) to also reduce thermal stresses between it and an exterior, protective layer (19) of a curable plastics material. The molded layer (17) can also cover the whole area of the waveguides (9) to form an upper cladding thereof.Type: GrantFiled: January 29, 1997Date of Patent: October 6, 1998Assignee: Telefonaktiebolaget LM EricssonInventors: Odd Steijer, Paul Eriksen, Hans Moll, Jan .ANG.ke Engstrand, Goran Palmskog, Mats Janson, Pia Tinghag
