About this file
This is a Salient Characteristics document that outlines the minimum specifications and technical requirements for a Fiber Optic Draw Tower system. The Naval Research Laboratory (NRL) seeks a fully turnkey silica fiber optic draw tower capable of drawing various fiber types including step index multimode, graded index multimode, single mode, microstructured photonic crystal fibers, and hollow core fibers. The system must fit within a 1-meter wide by 1-meter deep by 9-meter tall footprint and include a resistive, water-cooled furnace with a maximum temperature of 2,300°C, a preform feed mechanism, four independent channels of pressurization/vacuum control, two independent fiber coating systems with 365-nanometer LED UV curing capability, and two independent fiber coating measurement systems with data logging functionality.
The technical specifications require the draw tower to process preforms ranging from 10 to 50 millimeters in diameter (typically 12-30 millimeters) at speeds of 1 to 200 meters per minute, producing fiber diameters from 80 to 1,000 micrometers with a tolerance of ±0.1 micrometers. Additional capabilities include fiber draw tension monitoring (0-500 grams minimum), simultaneous fiber tapering with pressure variation programming, and a belt/caterpillar capstan system for silica cane and tube processing. The system must include software with full source code access to enable NRL personnel to add hardware and functionality modifications, potentially including classified or ITAR-restricted enhancements. All specifications are subject to change pending market survey and engineering review by NRL personnel.
