Rainbow Communications proposes to investigate MicroElectroMechanical System (MEMS) and double-layer nozzle based portable fiber-optic connector cleaners, which do not require the disassembly of connectors. Rainbow?_s proposed fiber-optic cleaner will include the following unique features. (1) Faster and more effective than cleaning swabs based on the double-layer nozzle to deliver compressed, filtered air and solvent, and suck them back to remove particles and contaminations; (2) No scratching to the connector surface because only air and solvent will contact the connector surfaces; (3) Applicable to all kinds of fiber-optic connectors, including MIL-T-29504 termini and standard fiber-optic connector ferrules based on changeable external needle of the proposed double-layer nozzle; (4) Fast and residue free as the solvent dries rapidly as well as vacuum sucking; (5) Lightweight
