Fiber optic switch ndi chida chothamanga kwambiri chapaintaneti, chomwe chimatchedwanso fiber channel switch kapena SAN switch.Poyerekeza ndi masiwichi wamba, imagwiritsa ntchito chingwe cha fiber optic ngati cholumikizira.Ubwino wa kufala kwa fiber optical ndi liwiro lachangu komanso mphamvu zotsutsana ndi kusokoneza.Pali mitundu iwiri ikuluikulu ya masiwichi a fiber optic, imodzi ndi masinthidwe a FC omwe amagwiritsidwa ntchito kulumikiza posungira.Chinacho ndi chosinthira cha Efaneti, dokoli ndi mawonekedwe owoneka bwino, ndipo mawonekedwe ake ndi ofanana ndi mawonekedwe wamba amagetsi, koma mawonekedwe amtundu ndi wosiyana.

Popeza mulingo wa protocol wa Fiber Channel udapangidwa ndi ANSI (American Industrial Standards Protocol), ukadaulo wa Fiber Channel walandira chidwi chachikulu kuchokera kuzinthu zonse.Ndi kuchepa kwapang'onopang'ono kwa mtengo wa zida za fiber channel komanso kuwonekera kwapang'onopang'ono kwa kuchuluka kwa kufalikira, kudalirika kwakukulu, ndi zolakwika zochepa zaukadaulo wa fiber channel, anthu akuyang'ana kwambiri ukadaulo wa fiber channel.Ukadaulo wa Fiber Channel wakhala gawo lofunikira kwambiri pakukwaniritsidwa kwa ma network osungira.Kusintha kwa Fiber Channel kwakhalanso zida zoyambira zomwe zimapanga netiweki ya SAN, ndipo ili ndi malo ofunikira ndi ntchito.Kusintha kwa Fiber Channel ndi gawo lofunikira pamaneti osungira malo, ndipo magwiridwe ake amakhudza mwachindunji magwiridwe antchito a network yonse yosungira.Ukadaulo wa Fiber Channel uli ndi topology yosinthika, kuphatikiza topology ya point-to-point, switching topology ndi ring topology.Pomanga netiweki, switching topology ndiyomwe imagwiritsidwa ntchito kwambiri.

Pambuyo pa kusintha kwa Fiber Channel kutembenuka kwa serial-to-parallel, 10B / 8B decoding, bit synchronization ndi synchronization mawu ndi ntchito zina pa data yolandiridwa yothamanga kwambiri, imakhazikitsa ulalo ndi seva ndi chipangizo chosungira cholumikizidwa kwa icho, ndipo mutalandira deta Pambuyo poyang'ana tebulo lotumizira, tumizani kuchokera ku doko lofanana kupita ku chipangizo chogwirizana.Monga chithunzi cha data cha Ethernet, chithunzi cha data cha chipangizo cha Fiber Channel chimakhalanso ndi mawonekedwe ake okhazikika komanso olamulira ake omwe adalamulidwa kuti agwirizane nawo.Malinga ndi mitundu yosiyanasiyana ya mautumiki, masinthidwe a Fiber Channel alinso ndi njira zofananira zakumapeto-ku-kumapeto kapena njira zowongolera mayendetsedwe a buffer-to-buffer.Kuphatikiza apo, kusintha kwa Fiber Channel kumaperekanso ntchito ndi kasamalidwe monga ntchito ya mayina, nthawi ndi ntchito zina, komanso ntchito yoyang'anira.
