Hoʻohana ʻia nā hono rotary puluniu e hala i nā hōʻailona ʻōnika ma waena o nā interface rotating, keu no ka nui o ka ʻikepili, i loaʻa i nā koho hoʻokahi a me nā kahawai maha, hiki ke hoʻohui ʻia me nā apo paheʻe uila e hāʻawi i kahi kuapo rotational interface no nā ʻōnika optical a me ka mana uila . Hana ʻia nā FORJ ma 1300 nm to1550 nm nā nalu lōʻihi singlemode a me 850 nm a 1300 nm multimode type, kākoʻo i nā loulou ʻikepili lōʻihi ma lalo o ka haʻalulu nui a me ka haʻalulu a i ʻole nā ​​wahi ʻoʻoleʻa. Mālama ʻo FORJs i nā pono intrinsic ʻaʻole maʻalahi e hoʻohuli ʻia e ke kaiapuni a hoʻokō i ka lawe pono pono ʻia, ʻae nā kino ʻino i nā pigtails fiber a i ʻole ST, FC mau ʻaoʻao ma ka ʻaoʻao rotor a i ʻole ka ʻaoʻao stator.
