Chifukwa chiyani ma SFP Optical modules ali otchuka?

Voliyumu yaSFP Optical moduleimachepetsedwa ndi theka poyerekeza ndi voliyumu ya GBIC Optical module. Chiwerengero cha madoko a SFP pagawo lomwelo chidzakhala kawiri kuposa cha GBIC Optical module. SFP optical module yomweyi ili ndi plug-and-play mini optical fiber slot, yomwe imagwirizana ndi deta Ndi zofunika kwambiri pakatikati, SFP optical modules idzalowa m'malo mwa GBIC optical modules m'malo opangira deta m'tsogolomu.

Ma module a SFP odziwika bwino

Chifukwa ma module a SFP optical a GLC-BX-D ndi GLC-BX-U ndi amphamvu komanso omwe amafunidwa kwambiri, mitundu iwiriyi ya ma module optical imathandizira kuwunika kwa data, zomwe zimalola ogwiritsa ntchito kuyang'anira momwe ma module akuwonekera munthawi yeniyeni, monga. Kutentha kotsatira, kuwala Kutulutsa mphamvu, kuwala kolowetsa mphamvu, laser bias current, transceiver power supply voltage, ndi zina zotero. 1000BASE-BX10-D SFP Optical module yokhala ndi mtunda wa 10km, GLC-BX40-D SFP Optical module yokhala ndi mtunda wa 40km, ndi GLC-BX80-D SFP Optical module yokhala ndi mtunda wa 80km. pakati pa ogwiritsa ntchito.

SFP Optical module ili ndi zabwino zinayi izi:

1. Imathandizira kusinthana kotentha, komwe kungachepetse nthawi yoyika, kukonza ndi kuyang'anira;

2. Doko limasinthasintha;

3. Mapangidwe olimba amakulitsa kudalirika;

4. Thandizani ntchito ya digito optical monitoring (DOM).

Kugwiritsa ntchito kwa SFP Optical module

1. Mawaya amtaneti akutali 1000BASE-T SFP Optical module imathandizira 10/100/1000 adaptive ndi Auto MDI/MDIX, ndipo ingagwiritsidwe ntchito ndi gulu la 5 zingwe zolumikizira maukonde osatetezedwa; mtunda wotumizira ukhoza kufika 100m. The 1000BASE-SX SFP Optical module imagwirizana ndi IEEE 802.3z 1000BASE-SX, ndipo ingagwiritsidwe ntchito mu ulalo wa fiber multimode 50μm / 62.5μm wokhala ndi mtunda wopitilira 550m.

2. Mawaya amtaneti akutali 1000BASE-EX ndi 1000BASE-ZX SFP optical modules angagwiritsidwe ntchito ndi ma single-mode optical fibers ndipo ndi oyenera kufalitsa maukonde akutali. Mtunda wotumizira wa 1000BASE-EX SFP optical modules ukhoza kufika 40km, ndipo mtunda wotumizira wa 1000BASE-ZX SFP optical modules ukhoza kufika 80km.

Zindikirani: Pamene single-mode fiber (SMF) ikugwiritsidwa ntchito kwa mtunda waufupi, kuti mupewe kuchulukira kwa wolandila, cholumikizira cholumikizira chiyenera kuyikidwa mu ulalo. Pambuyo poyambitsa pulogalamu yomwe ili pamwambapa, kodi mukuwona kuti doko la SFP limatha kuthandizira ma module amagetsi a SFP ndi ma module a SFP optical port? Ziribe kanthu momwe madoko a SFP ndi ma SFP optical modules ali ndi kusinthasintha kwakukulu komanso kugwirizanitsa muzogwiritsira ntchito, Yankho lanu labwino kwambiri la Gigabit Ethernet.
