In SMF, the optical signal propagates in an area of about 10 µm, so to connect the fiber, it must be positioned with a high precision of better than about 1 µm.
Ntawm qhov tod tes, nyob rau hauv ib qho optical connector, sab nraud rog yuav ua los ntawm optical cable. Tshwj xeeb tshaj yog nyob rau hauv lub optical kev sib txuas lus network, cov optical connectors yog ntsia rau ntawm lub davhlau ya nyob twg board ntawm ib tug siab ceev, thiab lub xov tooj chaw ua hauj lwm ua txoj kab hloov ua hauj lwm txhua txhua hnub, yog li cov cables ntawm cov kab uas twb muaj lawm feem ntau hu rau lub sij hawm ua hauj lwm. Kev sib txuas kev ua tau zoo yuav tsum nyob ruaj khov txawm tias thaum quab yuam siv rau cable.
The optical connector housing is also elastically deformed through physical contact technology, pressing the ferrules together to maintain a stable connection. This deformation can reach several tens of μm, and it is difficult to ensure the positioning accuracy required for the above-mentioned SMF. To avoid this problem, a floating mechanism is employed, in which the ferrule holding the optical fiber floats, and the deformation of the outer casing does not affect the positioning of the optical fiber.
Raws li tau hais los saum toj no, lub cev kev sib cuag tshuab thiab ntab tshuab tsim nyob rau hauv Nyij Pooj tau los ua lub hauv paus rau cov khoom siv kho qhov muag txuas ntxiv, uas yog siv nyob rau hauv tam sim no mainstream SC-hom thiab LC- hom optical connectors.
