34 very precise connectors ceramic ferrule singlemode or multimode. introduction this connector has a high precision ceramic ferrule in a cylindrical body. its spring-loaded free-floating ferrule and a screw- on mecha- nism with a precision anti-rotation key, ensure repeatable alignment with high performance physical contact, and reduce endface damage. suitable for both singlemode and multimode fibers in communication applications and instrumentation. available with pre-polished pc or apc ceramic ferrule. for 125?, 140? or 230? fibers 900? or 3mm boot for buffered fiber or cable. special versions are optimized for specific applications (see other pages) : polarization maintening fc ?asa?fc approuved for harsh environments main specifications insertion loss (typ) 0,15 db return loss (pc) < -45 db return loss (apc) typ.< -55 db temperature range -40? +85? cycles > 500 key 2,02 mm ?ide key?version 2,14mm on request standard single-mode connectors provide good characteristics in insertion and return loss. however, because the polarization ch a- racteristics of pm fibers are caused by stress, they are very sensitive to external stress. external stress can change the rota tional orien- tation of the optical axis and decrease extinction ratio.connectors for this type of fiber must provide a perfect rotationally aligned interface between the pm fibers without.additional stress. the pm connector performances must be better in : high quality materials, tight tolerances connector / adapter key. no internal sources of rotational looseness. tunable system to adjust alignment of optical axis / key connector. warning: stress can be induced during connectorization process, polishing, epoxy curing, bending and cabling...dont hesitate to contact us to have complete patchcord or pigtail on simplex cables or with 900? tight buffer. references fibers internal diameter (?) c1FC125JH03 singlemode pc 126 c1fc125jh02 singlemode apc 126 2553-2 gi 125 127 c1fc127jh04 gi 140 144 c1fc230jh02 hcs200 231 sleeve zirconium adaptors c1fc-rac-jh03 singlemode/multimode zirconium c1fc-rac-jh04 singlemode apc metal c1fc-rac-jh05 multimode fc connectors connectors for polarization maintening fibers
