Waa maxay sababta ay SFP modules indhaha u caan yihiin?

Mugga eemodule indhaha SFPwaxaa la dhimay kala bar marka loo eego mugga moduleka indhaha ee GBIC. Tirada dekedaha SFP ee isla gole ka mid ah waxay laba jibaar noqon doontaa moduleka indhaha ee GBIC. Isla moduleka indhaha ee SFP waxa uu leeyahay fur-iyo-ciyaar mini fiber fiber indhaha ah, kaas oo waafaqsan xogta Iyada oo shuruudaha cufnaanta sare ee xarunta, modules indhaha SFP ay bedeli doonaan modules indhaha GBIC ee xarumaha xogta mustaqbalka.

Qaybaha indhaha ee SFP ee caanka ah

Sababtoo ah qaybaha SFP ee GLC-BX-D iyo GLC-BX-U waa kuwo xoog badan oo aad loo raadsado, labadan nooc ee modules indhaha waxay taageeraan xogta kormeerka indhaha, taas oo u oggolaanaysa dadka isticmaala inay la socdaan waxqabadka modules-ka wakhtiga dhabta ah, sida heerkulka la socodka, iftiinka soo saarida awoodda, awoodda wax soo saarka indhaha, laser eexda hadda, transceiver danab korontada, iwm Intaa waxaa dheer, 1000BASE-BX10-D SFP module indhaha oo leh Masaafada gudbinta ee 10km, GLC-BX40-D SFP moduleka indhaha oo masaafo dhan 40km ah, iyo GLC-BX80-D SFP moduleka indhaha oo masaafo gudbin ah 80km ayaa sidoo kale caan ka ah isticmaalayaasha.

Qalabka indhaha ee SFP wuxuu leeyahay afar faa'iidooyin:

1. Waxay taageertaa isweydaarsiga kulul, kaas oo yarayn kara rakibidda, dayactirka iyo waqtiga maamulka;

2. Dekeddu waa dabacsan tahay;

3. Naqshadaynta adag waxay kor u qaadaysaa kalsoonida;

4. Taageerida shaqada kormeerka indhaha ee dhijitaalka ah (DOM).

Codsiga moduleka indhaha ee SFP

1. Xadhkaha shabakada fogaanta gaaban 1000BASE-T SFP module indhaha taageertaa 10/100/1000 laqabsiga iyo Auto MDI / MDIX, oo waxaa loo isticmaali karaa la category 5 xadhkaha balastar network aan gaashaan lahayn; fogaanta gudbinta waxay gaari kartaa 100m. Qalabka indhaha ee 1000BASE-SX SFP wuxuu la jaan qaadayaa heerka IEEE 802.3z 1000BASE-SX, waxaana loo isticmaali karaa 50μm/62.5μm multimode fiber link oo leh masaafada ugu badan ee gudbinta ee 550m.

2. Xadhkaha shabakada fogfog 1000BASE-EX iyo 1000BASE-ZX SFP modules indhaha waxaa loo isticmaali karaa fiilooyin muuqaal ah oo hal qaab ah waxayna ku habboon yihiin gudbinta shabakada fogaanta. Masaafada gudbinta ee 1000BASE-EX SFP modules indhaha waxay gaari kartaa 40km, masaafada gudbinta ee 1000BASE-ZX SFP modules indhaha waxay gaari kartaa 80km.

Fiiro gaar ah: Marka fibre-hal-mode (SMF) loo isticmaalo masaafo gaaban, si looga fogaado culeyska xad-dhaafka ah ee soo-dhoweynta, attenuator indhaha ayaa loo baahan yahay in la geliyo xiriirka. Hordhaca barnaamijka kore ka dib, miyaad aragtay in dekeda SFP ay taageeri karto labada qaybood ee dekeda korantada ee SFP iyo modules-ka dekeda indhaha ee SFP? Si kastaba ha ahaatee sida dekedaha SFP iyo modules indhaha SFP ay u leeyihiin dabacsanaan sare iyo waafaqsanaanta codsiyada la taaban karo, Xalkaaga ugu fiican ee Gigabit Ethernet.
