Kodi SFP module ndi chiyani?

SFP module ndi chipangizo cholumikizira chomwe chimasintha ma siginecha amagetsi a gigabit kukhala ma sign optical. Ndi gawo laling'ono lokhazikika la gigabit optical transceiver lomwe limatha kulumikizidwa mu SFP ya zida zama netiweki monga ma switch, ma routers, ndi zosinthira media. Dokoli limagwiritsidwa ntchito kulumikiza zingwe zamagetsi zamagetsi kapena zamkuwa potumiza deta. Nthawi zambiri timatha kuzipeza mu ma switch a Efaneti, ma routers, ma firewall ndi makadi olumikizira maukonde.

Kodi doko la SFP ndi chiyani?

Monga tafotokozera pamwambapa, madoko a SFP amapezeka mu zida zapaintaneti monga masiwichi, ma routers, osinthira media, ndi zina zambiri. Kodi mumadziwadi madoko a SFP? Doko la SFP limagwiritsidwa ntchito makamaka potembenuza ma siginecha komanso kutumiza ma data. Doko lake limagwirizana ndi IEEE 802.3ab muyezo (monga 1000BASE-T), ndipo mtunda wautali wotumizira ukhoza kufika 1000 Mbps (doko la SFP la switch limathandizira 100/1000 Mbps).

Ubwino wa doko la SFP

Doko la SFP ndi mawonekedwe otenthetsera a I/O (ponena za mawonekedwe olowera / zotulutsa), omwe amatha kusinthasintha mwamphamvu ndipo ndi oyenera pazinthu zosiyanasiyana, monga 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX kapena Madoko a 1000BASE -BX10-D/U amatha kusinthana, ndipo doko la SFP limagwirizana kumbuyo, kuchirikiza 10/100/1000Mbps.

SFP doko la Gigabit switch

Doko la SFP la switch ya Gigabit lingagwiritsidwe ntchito kukulitsa ntchito yosinthira maukonde onse polumikiza mitundu yosiyanasiyana ya ulusi wamaso (monga single-mode ndi multi-mode fiber) ndi ma jumpers a network (monga Cat5e ndi Cat6), koma doko la SFP la switch ya Gigabit The SFP Optical module iyenera kuyikidwa musanagwiritse ntchito, kenako gwiritsani ntchito ma fiber jumpers ndi ma network jumpers potumiza deta. Masiku ano, masinthidwe onse amakampani pamsika ali ndi madoko osachepera awiri a SFP, omwe amatha kupanga ma topologies amtundu wa mphete kapena nyenyezi pakati pa nyumba zosiyanasiyana, pansi kapena zigawo kudzera kulumikizidwa kwa zingwe monga ulusi wamaso ndi ma jumper a network.
