Proton™ consistently achieves Telcordia compliant, singlemode UPC and APC finishes in a handheld and battery operated package. Proton™ incorporates the same Independent Suspension (IS) and optically aligned workholder design found in Krell’s Scepter™ Mass Production Polishing Systems. Proton™ can polish connectors sideways and at most orientations, permitting access to cabling in the tight confines of datacom wire closets, LAN cross-connects, and CATV fiber nodes. Proton™’s portability lends itself to various military and aerospace applications and networks in which field-deployed optical connectors are terminated or require servicing and repair. Mil-spec components and termini including M29504, LuxCis, ARINC 801, ELIO, MC5, RSC etc.
