Kodi module ya SFP ndi chiyani?
SFP ndiye chidule cha phukusi laling'ono pluggable. Ndi compact, yotentha pluggable Optical module ya telecommunication ndi deta kulankhulana ntchito. SFP Optical module ikhoza kuonedwa ngati mtundu wosinthidwa wa GBIC Optical module. Mosiyana ndi ma GBIC okhala ndi SC fiber interfaces, SFPs amabwera ndi LC interfaces (ngakhale palinso ma modules a SFP okhala ndi SC interfaces) ndipo ali ndi kukula kwa thupi pafupifupi theka la GBICs, kulola SFPs kusunga malo ambiri. SFP imalumikiza boardboard ya zida zama netiweki (mongama routers, masiwichi, zosinthira media, kapena zida zofananira) kupita ku zingwe zowunikira kapena zingwe. Nthawi yomweyo, SFP ndizomwe zimagwiritsidwa ntchito nthawi zambiri m'mafakitale omwe amathandizidwa ndi ambiri ogulitsa zida zamagetsi. Zapangidwa kuti zithandizire SONET, Gigabit Ethernet, Fiber Channel, ndi njira zina zoyankhulirana. Maonekedwewo akuwonetsedwa mu chithunzi chotsatirachi
Kukhazikika
SFP Optical module siyimayendetsedwa ndi dongosolo lililonse lovomerezeka, koma imayendetsedwa ndi mgwirizano wamayiko osiyanasiyana (MSA) pakati paopikisana nawo. SFP idapangidwa molingana ndi mawonekedwe a GBIC ndipo imakwaniritsa kuchuluka kwa doko kuposa GBIC (chiwerengero cha Optical module pa centimita m'mphepete mwa bolodi), chifukwa chake SFP imatchedwanso mini GBIC. Pulojekiti yaying'ono yokhudzana ndi gawo la Optical ili ndi kukula kofanana ndi SFP, koma imagulitsidwa ku bolodi ngati pini m'malo moyikamo kagawo kakang'ono kakhadi.
Komabe, pakugwiritsa ntchito, opanga zida zina zapaintaneti amagwiritsa ntchito makina ofunikira kuti athetse kuyanjana ndi "Universal" SFP, ndiko kuti, yonjezerani njira yotsimikizira ku firmware ya chipangizocho kuti chipangizocho chizitha kungoyambitsa gawo lake la Optical.
Mitundu yosiyanasiyana ya SFPs
Pali mitundu yambiri yosiyanasiyana ya ma transmitters ndi olandila ma module a SFP omwe amagulitsidwa pamsika lero. Njirayi imalola ogwiritsa ntchito kusankha gawo loyenera la Optical pa ulalo uliwonse wosiyana. Mwachitsanzo, mumitundu yamawonekedwe apano, kufalitsa kumatha kugawidwa munjira imodzi kapena ma multimode kutengera mitundu yosiyanasiyana ya ulusi.
Monga momwe tawonetsera pamwambapa, chithunzichi chikuwonetsa gawo limodzi la fiber la mawonekedwe a SC
Monga momwe tawonetsera pamwambapa, iyi ndi gawo lachiwiri la fiber pa mawonekedwe a LC
Chithunzi cha SFP
Kapangidwe kakapangidwe kake: makamaka amapangidwa ndi imodzi mwa (BOSA ya ulusi umodzi; TOSA + ROSA ya ulusi wapawiri), wophatikizidwa ndi bolodi la PCBA ndi chipolopolo, ndipo amakhala ndi mphete zokoka, zomangira, zotsegula, ndi mapulagi a rabara. Pofuna kusiyanitsa bwino mafunde osiyanasiyana otulutsa ndi kulandira mafunde kuchokera kumawonekedwe, mitundu yosiyanasiyana ya mphete yokoka nthawi zambiri imapangidwa kuti isiyanitse mitundu ya magawo a module. Mwachitsanzo, mu mawonekedwe a LC single fiber, mphete yokoka buluu ndi 1310nm, mphete yofiirira ndi 1490nm, ndi zina zotero.
Gawo la SFP lopangidwa ndi Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. ndi chinthu chogulitsidwa kwambiri. Kuphatikiza apo, palinso njira zolumikizirana zodziwika bwino za Optical module, pluggable Optical module, 1x9 Optical module, dual core Optical module ndi zinthu zina zamitundu yosiyanasiyana. Landirani aliyense amene akufunika kukhala ndi chidziwitso cha malonda. Shenzhen Haidwiwei Optoelectronics Technology Co., Ltd. ikhoza kukupatsani gulu laukadaulo laukadaulo kuti likutumikireni.
