An optical fiber array unit of an optical connector includes an opposing pair of grooved plates holding at least three rows of optical fibers between them, with at least some of the optical fibers in each of the at least three rows touching two optical fibers of an adjacent one of the at least three rows. Each grooved plate of the opposing pair has an array of parallel fiber-holding grooves. In some implementations, a groove pitch of the array may be such that the cores of the optical fibers are located at nodes of a square lattice.

Optical fiber array connector device

An optical connector includes a fiber positioning assembly and a frame having two walls for supporting the fiber positioning assembly in a controlled vertical alignment relative to the frame. The fiber positioning assembly includes an optical fiber array disposed at a top surface of a support block for positioning between the walls, and a cap covering top portions of the optical fibers projecting from the block. The cap has a flat alignment surface resting upon the fiber top portions and extending laterally beyond the support block such that when the block is disposed between the walls, free portions of the alignment surface rest upon the walls to control the vertical alignment of the array. A single rail affixed to a bottom shelf of the frame, and a correspondingly dimensioned rectangular notch at the bottom of the support block, control the horizontal alignment of the array.

The present invention relates to high-strength high-toughness low-temperature thick-plate structural steel and a heat treatment method thereof. The steel is composed of the following components by weight percentage: C: 0.03-0.08%, Cr: 0.8-1.9%, Mn: 0.01-1.0%, Ni: 3.5-7%, Mo: 0.2-0.5%, V: 0.15-0.2%, Nb: 0.01-0.05%, Cu: 1.2-3.8%, Al: 0-0.5%, P: &#x3c;0.015%, S: &#x3c;0.010%, and Fe and inevitable impurities as balance. Compared with the prior art, a steel plate prepared in the present invention can be used at low temperature of &#x2212;20 to &#x2212;120&#xb0; C. and &#x2212;196&#xb0; C., maintains relatively high strength and certain toughness, and mainly resolves a technical problem that existing high-strength high-toughness quenched and tempered steel cannot meet equipment requirements in polar resource and energy development; transportation, etc.
