SFP-Transceiver: nufi, iri, siffofin

Inganta watsa bayanai fasahar ya kai ga zargin fiber-na gani cibiyar sadarwa, wanda shi ne dole a haɗa shi da na'urar yin amfani da musamman kayan aiki - SFP-transceiver. SFP kayayyaki sun maye gurbin da mafi amfani da tsauraran matakan kayan aiki amfani a cikin GBIC da kuma sadarwa Lines tare da gudun yawo fi 100 Mbit da na biyu.

SFP-radiyo suna amfani da kayan aiki priemoperedatochnogo. A wasu kalmomin, da suka yi aiki a matsayin shamaki tsakanin fiber-na gani na USB ko unshielded juya biyu, kuma cibiyar sadarwa katin na'urar - canji, na'ura mai ba da hanya tsakanin hanyoyin sadarwa ko modem. Babban amfani da module connector ne kadan. Saboda wannan, SFP-transceiver da nisa daga 20 cm iya saukar da har zuwa 20 ramummuka.

A kayan aiki da ake amfani da high data kudi (fiye da 10 megabits da na biyu) ga wadannan fasahar: SDH da Fiber Channel. Bugu da kari, kowa kayan aiki, wanda zai iya rike iri uku watsa shirye-shirye sigina.

Iri SFP-Transceiver

Dangane da aiki, kamar fiber-na gani na USB, kazalika da kayan aiki amfani, duk SFP kayayyaki an rarraba bisa ga dama sharudda:

1. The canja wurin bayanai kudi. Average SFP-transceiver retransmits da sigina a 100 Mb / s da kuma 1 Gbit / s, SFP + XFP matsayin da - har zuwa 10 Gb / s.
2. A irin haši. SC-Ramin amfani to connect guda-fiber na USB, inda da liyafar da kuma watsa bayanai auku a kan wanda fiber, kuma LC-connector - for biyu-fiber, inda liyafar da kuma watsa sakonni za'ayi a kan tashoshi.
3. Irin fiber. Don haɗi zuwa waya guda da ake amfani da SM-transceiver da multimode - MM kayayyaki.
4. Mai ikon da daukar kwayar cutar sigina. Wannan halayyar dabam a cikin kewayon 1310 nm da kuma 1550 nm for single-yanayin sadarwa, da kuma a cikin 850 nm da kuma 1310 nm for multimode igiyoyi.

Kowane SFP-Tantancewar transceiver yana da wani kasafin kudin, ko wani fanni na siginar liyafar da kuma watsa. Tare da nassi daga haske ta wurin na USB ne attenuated sigina. Bambanci tsakanin iyakar nesa da cewa a koyaushe ne iya aika wata sigina da kuma ikon da samu haske juyi, da ake kira Tantancewar kasafin kudin. Wadannan data nuna a cikin takardar bayanai na transceiver a DB.

Aiki tare da kayayyaki

A lokacin canja wurin bayanai SFP module fitarda wata sigina haske a cikin ganuwa bakan (akwai wani musamman Laser don wannan manufa ciki da kayan aiki). Saboda haka tsananin haramta a duba cikin "ido" na na'urar don kauce wa lalacewar da akan tantanin ido.

Danganta SFP transceiver dole ne sa a wuyan hannu munduwa, bayan da a haɗa shi da gidaje. In ba haka ba, yanzu na electrostatic sallama iya lalata nema.

Bugu da kari, da "ido" na Laser ne m zuwa turɓãya, don haka ba cire m inuwõyi kafin juya a kan na'urar da cibiyar sadarwa. Tsawanta da sabis module, ka mai da hankali ba to cire na USB daga unnecessarily.

Selection Dokokin SFP-kayayyaki

Zabi da SFP-transceiver dole ne daidai da halaye na your fiber-na gani na USB. Wajibi ne a mayar da hankali a kan 'yan batutuwa. Da fari dai, wajibi ne a daidai ƙayyade Tantancewar kasafin kudin. Mun bayar da shawarar yin amfani da musamman na'urorin. Inda akwai m, za ka iya gano darajar "kamar", shi ne isa ya san nesa tsakanin batu na liyafar da kuma watsa har zuwa wani kilometer.

Na biyu, sanin irin sakata a kan jirgin na cibiyar sadarwa na'urar. Tantancewar SFP transceiver dole ne a zabi tare da daidai da wannan kulle. In ba haka ba, za ka kawai ba zai iya yin amfani da koyaushe. A halin yanzu a kasuwa za a iya samu kida tare da latches na uku iri: Button, Mylar Tab, Bale-runguma. Za ka iya sanin da irin gani.
