SFP-Transceiver: whakaaro, momo, āhuatanga

Te whakapai ake hangarau tuku raraunga kua arahina ki te putanga o te whatunga muka-whatu, i te mea e tika ana ki te hono i te pūrere ki te whakamahi i ngā taputapu motuhake - SFP-transceiver. Kua whakakapi te taputapu atu cumbersome whakamahia i roto i te rārangi GBIC me aratuku ki te tere tarere ki runga ake i te 100 Mbit ia tuarua kōwae SFP.

iku'anga

E whakamahia SFP-transceivers rite taputapu priemoperedatochnogo. I roto i te mau parau te tahi atu, mahi ratou rite takawaenga i waenganui i te taura muka-whatu ranei unshielded rua whiria, me pūrere kāri whatunga - pana, pouara ranei pouwhanga. He iti rawa te painga matua o te tūhono kōwae. Nā ki tenei, SFP-transceiver ki te whanui o te 20 cm e taea hāngai ake ki te 20 i'ai.

Kei te whakamahia te taputapu mō te auau tiketike raraunga (neke atu i te 10 megabits ia rua) mo nga hangarau e whai ake nei: SDH me te muka Channel. I tua atu, taputapu noa, i taea ki te hapai i toru ngā momo o te haapurororaa tohu ko.

Momo o SFP-Transceiver

Tei runga i te mahi, pērā i te taura muka-whatu, me te te taputapu e whakamahia ana, e wehea kōwae SFP katoa rite ki te maha paearu:

1. Ko te auau whakawhiti raraunga. Toharite SFP-transceiver retransmits te tohu i 100 Mb / s, me 1 Gbit / s, paerewa SFP + XFP me - ki runga ki te 10 GB / s.
2. Ko te momo o te tūhono. SC-mokamoka whakamahia ki te hono i te taura kotahi-muka, te wahi puta te fariiraa me tuku o te mōhiohio i runga i te muka kotahi, a LC-tūhono - mō te rua-muka, te wahi i te fariiraa me tuku o tohu kawea i runga i te hongere.
3. Momo o te muka. Hei te hono ki te waea kotahi whakamahia te SM-transceiver me multimode - MM kōwae.
4. mana te nuinga o te tohu tuku. rerekē tēnei āhuatanga i roto i te whānuitanga 1310 nm, me 1550 nm mō hononga-aratau kotahi, a i roto i te 850 nm me 1310 nm mō taura multimode.

Ia transceiver SFP-whatu he tetahi pūtea, he whānui o te tohu fariiraa me te tuku ranei. Ki te wahi o te marama i roto i te taura, ko te tohu attenuated. Ko te rerekētanga i waenganui i te tawhiti mōrahi e te kōwae e taea ki te unga i te tohu, me te mana o te rere marama riro, a ka kua karangatia e pūtea whatu. Ēnei raraunga tohua i roto i te whārangi raraunga o te transceiver i DB.

Te mahi ki te kōwae

I roto i te whakawhiti raraunga E faatae mai SFP kōwae he marama tohu i roto i te tūāwhiorangi kitea (i reira he he taiaho motuhake mō tenei whakaaro i roto i te taputapu). Na reira tino rāhuitia ki te titiro ki te "kanohi" o te pūrere ki te karo kino ki te etine.

Hono SFP transceiver me kakahu he poroporo ringa, i muri i te tūhono i te reira ki te whare. Kore, ko te nāianei o te rere hiko kia tūkino i te taputapu.

I tua atu, he tairongo ki te puehu i te "mata" o te taiaho, na e kore e tango i te rakau tiaki i mua i tahuri i runga i te pūrere ki te whatunga. Hei roa te kōwae mahi, kia tupato e kore ki te tango i te taura i faufaa ore.

Tīpakonga Ture SFP-kōwae

Kōwhiri Me te SFP-transceiver i runga i nga āhuatanga o tō taura muka-whatu. He mea tika ki te arotahi ki runga i te torutoru take. Tuatahi, he mea e tika ana ki te tika te whakatau i te pūtea whatu. Ka tūtohu mātou te whakamahi i ngā pūrere motuhake. Hea i reira he kahore, ka taea e kitea e koe i roto i te uara o "āhua", he reira rawaka ki mohio te tawhiti i waenganui i te wāhi o te fariiraa me te tuku o runga ki te kiromita.

Tuarua, whakatau i te momo o te kohao i runga i te poari o tō pūrere whatunga. Me tīpakohia transceiver SFP Optical ki rite te raka taua. Kore, koe e kore noa e taea ki te whakamahi i te kōwae. I tēnei wā i runga i te mākete taea te kitea mea ki kēti o ngā momo e toru: Pātene, Mylar Ripa, Pera-papaki. Ka taea e koe te whakatau i te momo o ngā.
