Te whakataki taketake o te kōwae whatu
Ko te kōwae whatu he mea titoa he taputapu optoelectronic, iahiko mahi me nga atanga whatu. Ko nga taputapu optoelectronic e rua nga waahanga: te tuku me te whiwhi. I roto i te poto, ko te mahi o te kōwae whatu ko te huri i te tohu hiko ki te tohu whatu i te mutunga tuku. I muri i te tukunga o te tohu whatu i roto i te muka whatu, ka huri te mutunga whiwhi i te tohu whatu ki te tohu hiko.
Ko te waahanga tuku ko: ko te tohu hiko whakauru o tetahi reiti moka ka tukatukahia e te maramara puku o roto, katahi ka peia te laser semiconductor (LD) me te diode marama (LED) ki te whakaputa i te tohu whatu whakahuri o te reiti e rite ana. Ko te ara iahiko mana aunoa mana whatu o roto kua rite ki te pupuri i te mana tohu whatu whakaputa.
Ko te waahanga whiwhi: ko te waahanga whakauru tohu tohu me te reiti moka ka huri hei tohu hiko e te diode kitenga whatu, a ko te tohu hiko me te reiti moka e rite ana ka puta i muri i te preamplifier.
-Aria taketake o te kōwae whatu-
Ko te kōwae tauranga-optical te ingoa whānui o ngā kāwai kōwae rerekē, te tikanga e pā ana ki te kōwae whakauru whatu transceiver
-Mahi o te kōwae whatu-
Ko tana mahi he mohio noa ki te hurihanga i waenga i nga tohu tohu me nga tohu hiko.
-Hanga kōwae whatu-
I te nuinga o te wa ka titohia te kōwae whatu he kaiwhakawhiti whatu, kaiwhiwhi whatu, iahiko mahi me te atanga whatu (hiko).
I te kaikawe, ka tukatukahia e te maramara taraiwa te tohu hiko taketake, katahi ka peia te laser semiconductor (LD) me te diode maramara (LED) ki te whakaputa i te tohu whatu.
Ko te tauranga kei te pito whiwhi. Whai muri i te urunga mai o te tohu whatu, ka huri hei tohu hiko e te diode rapunga whatu, katahi ka whakaputa tohu hiko ma te preamplifier.
-Whakaraupapa aratau mata-
-Hitori whanaketanga o te aratau whatu-
-He kupu whakataki ki te takainga kōwae whatu-
He maha nga paerewa kapi mo nga waahanga whakaata, na te mea:
》He tere rawa te whanaketanga o te hangarau whakawhitiwhiti muka whatu. Kei te piki haere te tere o te kōwae whatu, kei te mimiti haere hoki te rōrahi, na ia tau, ka tukuna nga tapanga kapi hou.
tika He uaua ano hoki te hototahi i waenga i nga paerewa putunga hou me te tawhito.
》He kanorau nga ahuatanga tono o nga waahanga whatu. Rerekē tawhiti tuku, whakaritenga hōkaiipurangi, me nga waahi whakamahi, e rite ana ki nga momo momo muka whatu e whakamahia ana, he rereke ano nga momo waahanga.
Tauranga GBIC
Ko te GBIC ko Giga Bitrate Interface Converter.
I mua i te tau 2000, ko te GBIC te putunga kōwae whatu rongonui me te puka kōwae gigabit tino whakamahia.
Tauranga SFP
Na te nui o te GBIC, ka puta mai a SFP i muri mai ka timata ki te whakakapi i te GBIC.
SFP, te ingoa katoa o Small Form-Factor Pluggable, he kōwae whatu wera-swappable iti. Ko tona rahi iti e pa ana ki te kohinga GBIC. Ko te rahi o te SFP he haurua iti ake i te GBIC kōwae, ā, neke atu i te rua nga tau o nga tauranga ka taea te whirihora i runga i te papa kotahi. I runga i nga mahi, he iti noa te rereketanga i waenga i nga mea e rua, ka tautokohia e rua te whakauru wera. Ko te nui o te bandwidth e tautokohia ana e SFP ko 4Gbps
XFP waha
Ko te XFP he 10-Gigabit Small Form-Factor Pluggable, ka taea te mohio ki te titiro. He 10-Gigabit SFP.
Ka tango a XFP i tetahi kōwae rangatū hongere kotahi-tere katoa e hono ana e XFI (10Gb atanga rangatū), ka taea te whakakapi i a Xenpak me ona hua.
Tauranga SFP+
Ko te SFP+, he rite ki te XFP, he kōwae whatu 10G.
He rite te rahi o te SFP+ ki tera o te SFP. He iti ake i te XFP (he iti ake i te 30%), he iti ake hoki te kaha o te kaha (kua whakaitihia e etahi o nga mahi whakahaere tohu).
O SFP28
Ko te SFP me te tere o te 25Gbps na te mea he nui rawa te utu o nga waahanga 40G me 100G i taua wa, no reira i mahia tenei kaupapa whakawhiti whakararu.
QSFP/QSFP+/QSFP28/QSFP28-DD
Tapawhā Iti Puka-tauwehe Mono, wha-hongere atanga SFP. He maha nga hangarau matua pakeke i XFP kua whakamahia ki tenei hoahoa. Ka taea te wehea te QSFP ki te 4 kia rite ki te tere × 10G QSFP +, 4 × 25G QSFP28, 8 × 25G QSFP28-DD kōwae whatu, etc.
Tangohia te QSFP28 hei tauira, e pa ana ki te tauranga uru 4 × 25GE. Ka taea te whakamahi i te QSFP28 ki te whakapai ake i te 25G ki te 100G me te kore 40G, he tino ngawari te uaua o te taura me te whakaiti i nga utu.
QSFP/QSFP+/QSFP28/QSFP28-DD
Ko te QSFP-DD, i whakaturia i te Maehe 2016, e pa ana ki te "Double Density". Tāpirihia he rarangi hongere ki nga awa e 4 o te QSFP ka huri kia 8 nga hongere.
Ka taea te hototahi ki te kaupapa QSFP. Ka taea tonu te whakamahi i te waahanga QSFP28 taketake, me whakauru noa tetahi atu waahanga. Ko te maha o nga maihao koura o OSFP-DD he rua nga wa o te QSFP28.
Kei ia QSFP-DD te whakatakotoranga tohu 25Gbps NRZ, 50Gbps PAM4 ranei. Ma te PAM4, ka taea te tautoko ki te 400Gbps.
OSFP
OSFP, Octal Small Form Factor Pluggable, "O" e tu ana mo te "octal", i whakarewahia mana i te Whiringa-a-rangi 2016.
Kua hangaia ki te whakamahi i nga waahana hiko 8 ki te mohio ki te 400GbE (8 * 56GbE, engari ko te tohu 56GbE i hangaia e te laser 25G DML i raro i te whakarereketanga o PAM4), a he iti ake te rahi o tona rahi i te QSFP-DD. He pai ake te mahi tohanga wera o te miihini whatu me te transceiver me te hiko teitei ake.
CFP/CFP2/CFP4/CFP8
Centum gigabits Puka Mono, whakawehenga roangaru mātotoru kōwae whakawhitiwhiti whatu. Ka taea e te tere tuku te 100-400Gbpso
I hangaia te CFP i runga i te atanga SFP, he nui te rahi me te tautoko i te tuku raraunga 100Gbps. Ka taea e CFP te tautoko i te tohu 100G kotahi me te tohu 40G kotahi neke atu ranei.
Ko te rereketanga i waenga i te CFP, CFP2 me CFP4 he rōrahi. Ko te rōrahi o te CFP2 tetahi haurua o tera o te CFP, a ko te CFP4 tetahi hauwhā o te CFP. Ko te CFP8 he puka takai kua tohua mo te 400G, a ko tona rahi he rite ki te CFP2. Tautokohia nga reiti hongere 25Gbps me 50Gbps, me te mohio ki te reiti 400Gbps ma te 16x25G, 8x50 ranei atanga hiko.
