Fiber Optic Ribbon Cable

OFS (Norcross, GA) is expanding its AccuTube® “ribbon in loose tube” cable product line by offering the new AccuTube+ Rollable Ribbon (RR) Fiber Optic Cable. Available with 1728 and 3456 fibers, these cables can be installed in common 1¼” and 2” ducts, respectively. According to the manufacturer, the cables offer the significant time and cost savings benefits of 12-fiber mass fusion splicing, as compared with single fiber splicing, while getting the highest fiber density.

In a rollable ribbon cable, 12 fibers are connected intermittently by matrix material to form a very flexible ribbon, allowing the ribbons to be rolled into tight bundles, doubling the fiber density. These fibers can then be unrolled into a ribbon that can be spliced with traditional flat ribbon machines and procedures.

High Power Laser Diode Cooling Solutions

Curamik® CoolPerformance Plus is the latest cooling material from Rogers Corporation (Eschenbach, Germany). It is an advanced liquid-cooled material designed to dissipate large amounts of heat and provide reliable thermal management of high-power laser diodes operating at power levels to 200W or more.

CoolPerformance Plus coolers build upon the cooling approach employed in Rogers Curamik CoolPerformance coolers. Both types of coolers feature several layers of pure copper. The copper foils are formed into hermetic, three-dimensional microchannel or macrochannel water-cooled structures capable of dissipating large amounts of heat in small areas. In addition, they also have aluminum-nitride (AlN) isolation layers, which separate the cooling water channels from the electrical contacts of the laser diodes. They provide a close match in coefficient of thermal expansion (CTE), in the range of 6 to 7 ppm/K, between the copper cooling structures and the laser diode packages.

Optical Beam Alignment Tool

The new Light Aligner from Spectrolight (Irvine, CA) is a tool that solves the ubiquitous challenge of aligning a light beam through an optical system constructed on a breadboard or optical table. The Light Aligner is an anodized metal ruler with precision engraved fiducials and a series of 2.5 mm diameter through-holes. It utilizes a magnetic base that holds the ruler in a vertical orientation and enables its stable, temporary placement on any optical table, breadboard or ferrous metal surface. In use, the optical beam is passed through one of the holes at the appropriate height, and then the entire unit is moved as necessary to various positions in the optical system to verify that the beam alignment is being maintained.

The Light Aligner is available either with or without registration pins on its base, allowing for either complete freedom in its placement, or precise registration of a beam with the mounting hole pattern on the table or breadboard. The Light Aligner also uses a modular approach to provide maximum utility; a bolt-on extension doubles the height with no loss of precision. Both metric and imperial (inch) versions are available with standard lengths being 220 mm and 8.6 inches.
