Ko te kaiwhakawhitiwhiti muka whatu he taputapu hurihuri whakaahua hiko me te whai hua e whai waahi nui ana ki te LAN ranu photoelectric maha-kawa. Inaianei, kia pai ake ai te kite me te whakakore i nga hapa hono, kei etahi o nga kaiwhakawhiti whatu whatu he hononga failover (LFP) me te hapa mamao (FEF) mahi whakaoho.
I mua i te whakauru tuatahi i te hononga failover (LFP) me te hapa mamao (FEF) mahi whakaoho o te muka transceivers, he mea tika ki te mohio ki te mahi o te transceivers muka i roto i te LAN.
Ko te whakawhiti muka whatu he tauranga hiko me nga tauranga whatu, e whakamahia nuitia ana hei hono i te tauranga whatuwhakawhitime te tauranga hikowhakawhiti, kia rite ki te ite i te huringa photoelectric i waenganui i nga whakaaro e rua. Ko nga korero e whai ake nei:
E tika ana, ko te mahi matua o te whakawhiti muka whatu ko te whakahaere i te huringa photoelectric, he piriti i waenga i nga taputapu e rua e kore e taea te korero tika, engari ko tana mahi he nui atu i tera.
Ina whakamahia takirua te whakawhiti muka, ko nga taura e whakamahia ana kei roto i te iti rawa e rua nga taura muka me nga taura e rua (e whakaatu ana i raro nei). Ko te uaua o tenei taura e arai atu ana ki te hononga failover (LFP) me te hapa tawhiti (FEF) mahi whakaoho o te whakawhiti muka.
Ko te hono failover (LFP) e pa ana ki nga taputapu whakawhitiwhiti e rua (whakawhitiwhiti,whakawhiti, pouara, me etahi atu), tetahi (proximal) hono hono, ka taea te tuku i te he o te hono ki tetahi atu taputapu (mamao) hei tauira, e rua nga whakawhiti muka A me te B, He he hononga hono tauranga whakawhiti, te hapa o te tauranga whakawhiti ki te tauranga marama, ka mutu nga raraunga tauranga; Kaore e taea e te kaiwhakawhitiwhiti B te whiwhi raraunga A, ka mohio he he hononga hono, ka mutu te tauranga B te tauranga marama me te raraunga tauranga. Ko te mahi whakaoho hono failover (LFP) ka taea e nga kaiwhakahaere whatunga te mohio tere me te mahi i nga hapa o te whatunga me te whakaiti i te mate i puta mai i nga hapa whatunga.
Ko te hapa Mamao (FEF) e pa ana ki te whakawhiti muka whatu B ka mutu te tauranga whatu o A transceiver te tuku raraunga ki te tauranga whatu o te whakawhiti B. Mena ka pai te mahi o tetahi atu taura, ka tukuna tonutia e te tauranga whatu o B transceiver te raraunga ki te tauranga whatu o A transceiver, ka rahua te whatunga. Ko te mahi whakaoho o te hapa tawhiti (FEF) e whakaatu ana i tenei raru.
Ko te korero i runga ake nei ko te whakamaramatanga o nga mahi transceiver LFP me FEF i kawea mai e Shenzhen HDV Phoelectronic Technology Co., LTD. Ko o maatau taputapu whatunga he raupapa ONU,OLTrangatū, raupapa kōwae whatu, nau mai ki te whakawhitiwhiti whakaaro.
