Malingana ndi kuyesera, Gigabit SFP optical module ikhoza kugwira ntchito pa 10 Gigabit SFP + doko, koma 10 Gigabit SFP + optical module sangathe kugwira ntchito pa doko la Gigabit SFP. Pamene Gigabit SFP optical module imayikidwa mu 10 Gigabit SFP + doko, liwiro la doko ili ndi 1G, osati 10G. Nthawi zina dokoli limatsekedwa pa liwiro la 1G mpaka mutatsitsansokusinthakapena kupereka malamulo ena. Chifukwa chake nthawi zambiri, SFP Optical module imatha kuyikidwa mu doko la SFP +.
Kuphatikiza apo, madoko a SFP + nthawi zambiri samathandizira kuthamanga pansi pa 1G. Ndiko kunena kuti, sitingathe kuyika 100BASE SFP Optical module pa SFP + port. M'malo mwake, pavutoli, zimadalira kwambiriSinthani Sinthanichitsanzo. Madoko ena a SFP + amatha kuthandizira SFP, ena satero. Mwachitsanzo, pafupifupi madoko onse a SFP + a Cisco CISCO onsemasiwichithandizirani ma module a SFP, ndi madoko ambiri a SFP + a Brocademasiwichithandizani SFP + yokha. Ngakhale nthawi zambiri zimakhala zotheka, ndizotetezeka kutsatira zomwe zaperekedwa ndiSinthaniwogulitsa.
10G SFP + sichingagwirizane ndi ma module a Gigabit SFP
Nthawi zambiri, titha kugwiritsa ntchito ma SFP optical modules mu SFP + ports, koma izi sizikutanthauza kuti SFP Optical modules yomwe imayikidwa mu SFP + ports ikhoza kuthandizira 1G. Mu ulalo wa fiber optical, ngati tigwirizanitsa SFP optical module ndi SFP + optical module, sizingagwire bwino! Pa vutoli, ngati mugwiritsa ntchito chingwe cha SFP + chothamanga kwambiri, sichingakhale chosagwirizana ndi Gigabit SFP.
Ma module a SFP ndi SFP + optical omwe amagwiritsidwa ntchito mu network cabling ndi data center yomanga chipinda cha makompyuta ayenera kuonetsetsa kuti liwiro lomwelo pamapeto onse a ulalo wa fiber. Mwachitsanzo, doko la SFP + pamapeto amodzi limagwiritsa ntchito 10G SFP + 1310nm 10KM LC DDM optical module, ndipo mapeto ena amagwiritsa ntchito mawonekedwe omwewo. Ma module a single-fiber optical ayenera kuphatikizidwa.
